]
</p>
Garage is an S3-compatible distributed object storage service
designed for self-hosting at a small-to-medium scale.
Garage is a lightweight S3-compatible distributed object store, with the following goals:
Garage is designed for storage clusters composed of nodes running
at different physical locations,
in order to easily provide a storage service that replicates data at these different
locations and stays available even when some servers are unreachable.
Garage also focuses on being lightweight, easy to operate, and highly resilient to
machine failures.
- As self-contained as possible
- Easy to set up
- Highly resilient to network failures, network latency, disk failures, sysadmin failures
- Relatively simple
- Made for multi-datacenter deployments
Garage is built by [Deuxfleurs](https://deuxfleurs.fr),
an experimental small-scale self hosted service provider,
which has been using it in production since its first release in 2020.
Non-goals include:
Learn more on our dedicated documentation pages:
- Extremely high performance
- Complete implementation of the S3 API
- Erasure coding (our replication model is simply to copy the data as is on several nodes, in different datacenters if possible)
- [Goals and use cases](https://garagehq.deuxfleurs.fr/documentation/design/goals/)
- [Features](https://garagehq.deuxfleurs.fr/documentation/reference-manual/features/)
- [Quick start](https://garagehq.deuxfleurs.fr/documentation/quick-start/)
Garage is entirely free software released under the terms of the AGPLv3.
Our main use case is to provide a distributed storage layer for small-scale self hosted services such as [Deuxfleurs](https://deuxfleurs.fr).

Garage has many API that you can rely on to build complex applications.
In this section, we reference the existing SDKs and give some code examples.
## ⚠️ DISCLAIMER
**K2V AND ADMIN SDK ARE TECHNICAL PREVIEWS**. The following limitations apply:
- The API is not complete, some actions are possible only through the `garage` binary
- The underlying admin API is not yet stable nor complete, it can breaks at any time
- The generator configuration is currently tweaked, the library might break at any time due to a generator change
- Because the API and the library are not stable, none of them are published in a package manager (npm, pypi, etc.)
- This code has not been extensively tested, some things might not work (please report!)
To have the best experience possible, please consider:
- Make sure that the version of the library you are using is pinned (`go.sum`, `package-lock.json`, `requirements.txt`).
- Before upgrading your Garage cluster, make sure that you can find a version of this SDK that works with your targeted version and that you are able to update your own code to work with this new version of the library.
- Join our Matrix channel at `#garage:deuxfleurs.fr`, say that you are interested by this SDK, and report any friction.
- If stability is critical, mirror this repository on your own infrastructure, regenerate the SDKs and upgrade them at your own pace.
## About the APIs
Code can interact with Garage through 3 different APIs: S3, K2V, and Admin.
Each of them has a specific scope.
### S3
De-facto standard, introduced by Amazon, designed to store blobs of data.
### K2V
A simple database API similar to RiakKV or DynamoDB.
Think a key value store with some additional operations.
Its design is inspired by Distributed Hash Tables (DHT).
More information:
- [In the reference manual](@/documentation/reference-manual/k2v.md)
### Administration
Garage operations can also be automated through a REST API.
We are currently building this SDK for [Python](@/documentation/build/python.md#admin-api), [Javascript](@/documentation/build/javascript.md#administration) and [Golang](@/documentation/build/golang.md#administration).
More information:
- [In the reference manual](@/documentation/reference-manual/admin-api.md)

### Using Minio SDK
First install the SDK:
```bash
pip3 install minio
```
Then instantiate a client object using garage root domain, api key and secret:
```python
import minio
client = minio.Minio(
"your.domain.tld",
"GKyourapikey",
"abcd[...]1234",
# Force the region, this is specific to garage
region="region",
)
```
Then use all the standard S3 endpoints as implemented by the Minio SDK:
```
# List buckets
print(client.list_buckets())
# Put an object containing 'content' to /path in bucket named 'bucket':
content = b"content"
client.put_object(
"bucket",
"path",
io.BytesIO(content),
len(content),
)
# Read the object back and check contents
data = client.get_object("bucket", "path").read()
assert data == content
```
For further documentation, see the Minio SDK

## Admin API
You need at least Python 3.6, pip, and setuptools.
Because the python package is in a subfolder, the command is a bit more complicated than usual:
```bash
pip3 install --user 'git+https://git.deuxfleurs.fr/garage-sdk/garage-admin-sdk-python'
```
Now, let imagine you have a fresh Garage instance running on localhost, with the admin API configured on port 3903 with the bearer `s3cr3t`:
```python
import garage_admin_sdk
from garage_admin_sdk.apis import *
from garage_admin_sdk.models import *
configuration = garage_admin_sdk.Configuration(
host = "http://localhost:3903/v0",
access_token = "s3cr3t"
)
# Init APIs
api = garage_admin_sdk.ApiClient(configuration)
nodes, layout, keys, buckets = NodesApi(api), LayoutApi(api), KeyApi(api), BucketApi(api)
# Display some info on the node
status = nodes.get_nodes()
print(f"running garage {status.garage_version}, node_id {status.node}")
# Change layout of this node
current = layout.get_layout()
layout.add_layout({
status.node: NodeClusterInfo(
zone = "dc1",
capacity = 1,
tags = [ "dev" ],
)
})
layout.apply_layout(LayoutVersion(
version = current.version + 1
))
# Create key, allow it to create buckets
kinfo = keys.add_key(AddKeyRequest(name="openapi"))
allow_create = UpdateKeyRequestAllow(create_bucket=True)
keys.update_key(kinfo.access_key_id, UpdateKeyRequest(allow=allow_create))
# Create a bucket, allow key, set quotas
binfo = buckets.create_bucket(CreateBucketRequest(global_alias="documentation"))
binfo = buckets.allow_bucket_key(AllowBucketKeyRequest(
bucket_id=binfo.id,
access_key_id=kinfo.access_key_id,
permissions=AllowBucketKeyRequestPermissions(read=True, write=True, owner=True),
))
binfo = buckets.update_bucket(binfo.id, UpdateBucketRequest(
quotas=UpdateBucketRequestQuotas(max_size=19029801,max_objects=1500)))
# Display key
print(f"""
cluster ready
key id is {kinfo.access_key_id}
secret key is {kinfo.secret_access_key}
bucket {binfo.global_aliases[0]} contains {binfo.objects}/{binfo.quotas.max_objects} objects
""")
```

Backups are essential for disaster recovery but they are not trivial to manage.
Using Garage as your backup target will enable you to scale your storage as needed while ensuring high availability.
## Borg Backup
Borg Backup is very popular among the backup tools but it is not yet compatible with the S3 API.
We recommend using any other tool listed in this guide because they are all compatible with the S3 API.
If you still want to use Borg, you can use it with `rclone mount`.
## Restic
Create your key and bucket:
```bash
garage key new my-key
garage bucket create backup
garage bucket allow backup --read --write --key my-key
```
Then register your Key ID and Secret key in your environment:
```bash
export AWS_ACCESS_KEY_ID=GKxxx
export AWS_SECRET_ACCESS_KEY=xxxx
```
Configure restic from environment too:
```bash
export RESTIC_REPOSITORY="s3:http://localhost:3900/backups"
echo "Generated password (save it safely): $(openssl rand -base64 32)"
export RESTIC_PASSWORD=xxx # copy paste your generated password here
```
Do not forget to save your password safely (in your password manager or print it). It will be needed to decrypt your backups.
Now you can use restic:
```bash
# Initialize the bucket, must be run once
restic init
# Backup your PostgreSQL database
# (We suppose your PostgreSQL daemon is stopped for all commands)
restic backup /var/lib/postgresql
# Show backup history
restic snapshots
# Backup again your PostgreSQL database, it will be faster as only changes will be uploaded
restic backup /var/lib/postgresql
# Show backup history (again)
restic snapshots
# Restore a backup
# (79766175 is the ID of the snapshot you want to restore)
mv /var/lib/postgresql /var/lib/postgresql.broken
restic restore 79766175 --target /var/lib/postgresql
```
Restic has way more features than the ones presented here.
You can discover all of them by accessing its documentation from the link below.
*External links:* [Restic Documentation > Amazon S3](https://restic.readthedocs.io/en/stable/030_preparing_a_new_repo.html#amazon-s3)
## Duplicity
*External links:* [Duplicity > man](https://duplicity.gitlab.io/duplicity-web/vers8/duplicity.1.html) (scroll to "URL Format" and "A note on Amazon S3")
## Duplicati
*External links:* [Duplicati Documentation > Storage Providers](https://duplicati.readthedocs.io/en/latest/05-storage-providers/#s3-compatible)
The following fields need to be specified:
```
Storage Type: S3 Compatible
Use SSL: [ ] # Only if you have SSL
Server: Custom server url (s3.garage.localhost:3900)
Bucket name: bucket-name
Bucket create region: Custom region value (garage) # Or as you've specified in garage.toml
AWS Access ID: Key ID from "garage key info key-name"
AWS Access Key: Secret key from "garage key info key-name"
Client Library to use: Minio SDK
```
Click `Test connection` and then no when asked `The bucket name should start with your username, prepend automatically?`. Then it should say `Connection worked!`.
## knoxite
*External links:* [Knoxite Documentation > Storage Backends](https://knoxite.com/docs/storage-backends/#amazon-s3)
## kopia
*External links:* [Kopia Documentation > Repositories](https://kopia.io/docs/repositories/#amazon-s3)
To create the Kopia repository, you need to specify the region, the HTTP(S) endpoint, the bucket name and the access keys.
For instance, if you have an instance of garage running on `https://garage.example.com`:
```
kopia repository create s3 --region=garage --bucket=mybackups --access-key=KEY_ID --secret-access-key=SECRET_KEY --endpoint=garage.example.com
```
Or if you have an instance running on localhost, without TLS:
```
kopia repository create s3 --region=garage --bucket=mybackups --access-key=KEY_ID --secret-access-key=SECRET_KEY --endpoint=localhost:3900 --disable-tls
```
After the repository has been created, check that everything works as expected:
```
kopia repository validate-provider
```
You can then run all the standard kopia commands: `kopia snapshot create`, `kopia mount`...
Everything should work out-of-the-box.

title = "Exposing buckets as websites"
weight = 25
+++
## Configuring a bucket for website access
There are three methods to expose buckets as website:
1. using the PutBucketWebsite S3 API call, which is allowed for access keys that have the owner permission bit set
2. from the Garage CLI, by an adminstrator of the cluster
3. using the Garage administration API
The `PutBucketWebsite` API endpoint [is documented](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketWebsite.html) in the official AWS docs.
This endpoint can also be called [using `aws s3api`](https://docs.aws.amazon.com/cli/latest/reference/s3api/put-bucket-website.html) on the command line.
The website configuration supported by Garage is only a subset of the possibilities on Amazon S3: redirections are not supported, only the index document and error document can be specified.
If you want to expose your bucket as a website from the CLI, use this simple command:
```bash
garage bucket website --allow my-website
```
Now it will be **publicly** exposed on the web endpoint (by default listening on port 3902).
## How exposed websites work
Our website serving logic is as follow:
- Supports only static websites (no support for PHP or other languages)
- Does not support directory listing
- The index file is defined per-bucket and can be specified in the `PutBucketWebsite` call
or on the CLI using the `--index-document` parameter (default: `index.html`)
- A custom error document for 404 errors can be specified in the `PutBucketWebsite` call
or on the CLI using the `--error-document` parameter
Now we need to infer the URL of your website through your bucket name.
Let assume:
- we set `root_domain = ".web.example.com"` in `garage.toml` ([ref](@/documentation/reference-manual/configuration.md#root_domain))
- our bucket name is `garagehq.deuxfleurs.fr`.
Our bucket will be served if the Host field matches one of these 2 values (the port is ignored):
- `garagehq.deuxfleurs.fr.web.example.com`: you can dedicate a subdomain to your users (here `web.example.com`).
- `garagehq.deuxfleurs.fr`: your users can bring their own domain name, they just need to point them to your Garage cluster.
You can try this logic locally, without configuring any DNS, thanks to `curl`:
```bash
# prepare your test
echo hello world > /tmp/index.html
mc cp /tmp/index.html garage/garagehq.deuxfleurs.fr
curl -H 'Host: garagehq.deuxfleurs.fr' http://localhost:3902
# should print "hello world"
curl -H 'Host: garagehq.deuxfleurs.fr.web.example.com' http://localhost:3902
# should also print "hello world"
```
Now that you understand how website logic works on Garage, you can:
- make the website endpoint listens on port 80 (instead of 3902)
- use iptables to redirect the port 80 to the port 3902:
`iptables -t nat -A PREROUTING -p tcp -dport 80 -j REDIRECT -to-port 3902`
- or configure a [reverse proxy](@/documentation/cookbook/reverse-proxy.md) in front of Garage to add TLS (HTTPS), CORS support, etc.
You can also take a look at [Website Integration](@/documentation/connect/websites.md) to see how you can add Garage to your workflow.

title = "Compiling Garage from source"
weight = 10
+++
Garage is a standard Rust project. First, you need `rust` and `cargo`. For instance on Debian:
```bash
sudo apt-get update
sudo apt-get install -y rustc cargo
```
You can also use [Rustup](https://rustup.rs/) to setup a Rust toolchain easily.
In addition, you will need a full C toolchain. On Debian-based distributions, it can be installed as follows:
```bash
sudo apt-get update
sudo apt-get install build-essential
```
## Building from source from the Gitea repository
The primary location for Garage's source code is the
[Gitea repository](https://git.deuxfleurs.fr/Deuxfleurs/garage),
which contains all of the released versions as well as the code
for the developpement of the next version.
Clone the repository and enter it as follows:
```bash
git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
cd garage
```
If you wish to build a specific version of Garage, check out the corresponding tag. For instance:
```bash
git tag # List available tags
git checkout v0.8.0 # Change v0.8.0 with the version you wish to build
```
Otherwise you will be building a developpement build from the `main` branch
that includes all of the changes to be released in the next version.
Be careful that such a build might be unstable or contain bugs,
and could be incompatible with nodes that run stable versions of Garage.
Finally, build Garage with the following command:
```bash
cargo build --release
```
The binary built this way can now be found in `target/release/garage`.
You may simply copy this binary to somewhere in your `$PATH` in order to
have the `garage` command available in your shell, for instance:
```bash
sudo cp target/release/garage /usr/local/bin/garage
```
If you are planning to develop Garage,
you might be interested in producing debug builds, which compile faster but run slower:
this can be done by removing the `--release` flag, and the resulting build can then
be found in `target/debug/garage`.
## List of available Cargo feature flags
Garage supports a number of compilation options in the form of Cargo feature flags,
which can be used to provide builds adapted to your system and your use case.
To produce a build with a given set of features, invoke the `cargo build` command
as follows:
```bash
# This will build the default feature set plus feature1, feature2 and feature3
cargo build --release --features feature1,feature2,feature3
# This will build ONLY feature1, feature2 and feature3
cargo build --release --no-default-features \
--features feature1,feature2,feature3
```
The following feature flags are available in v0.8.0:
| Feature flag | Enabled | Description |
| ------------ | ------- | ----------- |
| `bundled-libs` | *by default* | Use bundled version of sqlite3, zstd, lmdb and libsodium |
| `system-libs` | optional | Use system version of sqlite3, zstd, lmdb and libsodium<br>if available (exclusive with `bundled-libs`, build using<br>`cargo build --no-default-features --features system-libs`) |
| `k2v` | optional | Enable the experimental K2V API (if used, all nodes on your<br>Garage cluster must have it enabled as well) |
| `kubernetes-discovery` | optional | Enable automatic registration and discovery<br>of cluster nodes through the Kubernetes API |
| `metrics` | *by default* | Enable collection of metrics in Prometheus format on the admin API |
| `telemetry-otlp` | optional | Enable collection of execution traces using OpenTelemetry |
| `sled` | *by default* | Enable using Sled to store Garage's metadata |

Garage can also be deployed on a kubernetes cluster via helm chart.
## Deploying
Firstly clone the repository:
```bash
git clone https://git.deuxfleurs.fr/Deuxfleurs/garage
cd garage/scripts/helm
```
Deploy with default options:
```bash
helm install --create-namespace --namespace garage garage ./garage
```
Or deploy with custom values:
```bash
helm install --create-namespace --namespace garage garage ./garage -f values.override.yaml
```
After deploying, cluster layout must be configured manually as described in [Creating a cluster layout](@/documentation/quick-start/_index.md#creating-a-cluster-layout). Use the following command to access garage CLI:
```bash
kubectl exec --stdin --tty -n garage garage-0 -- ./garage status
```
## Overriding default values
All possible configuration values can be found with:
```bash
helm show values ./garage
```
This is an example `values.overrride.yaml` for deploying in a microk8s cluster with a https s3 api ingress route:
```yaml
garage:
# Use only 2 replicas per object
replicationMode: "2"
# Start 4 instances (StatefulSets) of garage
replicaCount: 4
# Override default storage class and size
persistence:
meta:
storageClass: "openebs-hostpath"
size: 100Mi
data:
storageClass: "openebs-hostpath"
size: 1Gi
ingress:
s3:
api:
enabled: true
className: "public"
annotations:
cert-manager.io/cluster-issuer: "letsencrypt-prod"
nginx.ingress.kubernetes.io/proxy-body-size: 500m
hosts:
- host: s3-api.my-domain.com
paths:
- path: /
pathType: Prefix
tls:
- secretName: garage-ingress-cert
hosts:
- s3-api.my-domain.com
```
## Removing
```bash
helm delete --namespace garage garage
```
Note that this will leave behind custom CRD `garagenodes.deuxfleurs.fr`, which must be removed manually if desired.

title = "Monitoring Garage"
weight = 40
+++
Garage exposes some internal metrics in the Prometheus data format.
This page explains how to exploit these metrics.
## Setting up monitoring
### Enabling the Admin API endpoint
If you have not already enabled the [administration API endpoint](@/documentation/reference-manual/admin-api.md), do so by adding the following lines to your configuration file:
```toml
[admin]
api_bind_addr = "0.0.0.0:3903"
```
This will allow anyone to scrape Prometheus metrics by fetching
`http://localhost:3093/metrics`. If you want to restrict access
to the exported metrics, set the `metrics_token` configuration value
to a bearer token to be used when fetching the metrics endpoint.
### Setting up Prometheus and Grafana
Add a scrape config to your Prometheus daemon to scrape metrics from
all of your nodes:
```yaml
scrape_configs:
- job_name: 'garage'
static_configs:
- targets:
- 'node1.mycluster:3903'
- 'node2.mycluster:3903'
- 'node3.mycluster:3903'
```
If you have set a metrics token in your Garage configuration file,
add the following lines in your Prometheus scrape config:
```yaml
authorization:
type: Bearer
credentials: 'your metrics token'
```
To visualize the scraped data in Grafana,
you can either import our [Grafana dashboard for Garage](https://git.deuxfleurs.fr/Deuxfleurs/garage/raw/branch/main/script/telemetry/grafana-garage-dashboard-prometheus.json)
or make your own.
We detail below the list of exposed metrics and their meaning.

title = "Configuring a reverse proxy"
weight = 30
+++
The main reason to add a reverse proxy in front of Garage is to provide TLS to your users and serve multiple web services on port 443.
In production you will likely need your certificates signed by a certificate authority.
The most automated way is to use a provider supporting the [ACME protocol](https://datatracker.ietf.org/doc/html/rfc8555)
such as [Let's Encrypt](https://letsencrypt.org/), [ZeroSSL](https://zerossl.com/) or [Buypass Go SSL](https://www.buypass.com/ssl/products/acme).
If you are only testing Garage, you can generate a self-signed certificate to follow the documentation:
```bash
openssl req \
-new \
-x509 \
-keyout /tmp/garage.key \
-out /tmp/garage.crt \
-nodes \
-subj "/C=XX/ST=XX/L=XX/O=XX/OU=XX/CN=localhost/emailAddress=X@X.XX" \
-addext "subjectAltName = DNS:localhost, IP:127.0.0.1"
cat /tmp/garage.key /tmp/garage.crt > /tmp/garage.pem
```
Be careful as you will need to allow self signed certificates in your client.
For example, with minio, you must add the `--insecure` flag.
An example:
```bash
mc ls --insecure garage/
```
## socat (only for testing purposes)
If you want to test Garage with a TLS frontend, socat can do it for you in a single command:
```bash
socat \
"openssl-listen:443,\
reuseaddr,\
fork,\
verify=0,\
cert=/tmp/garage.pem" \
tcp4-connect:localhost:3900
```
## Nginx
Nginx is a well-known reverse proxy suitable for production.
We do the configuration in 3 steps: first we define the upstream blocks ("the backends")
then we define the server blocks ("the frontends") for the S3 endpoint and finally for the web endpoint.
The following configuration blocks can be all put in the same `/etc/nginx/sites-available/garage.conf`.
To make your configuration active, run `ln -s /etc/nginx/sites-available/garage.conf /etc/nginx/sites-enabled/`.
If you directly put the instructions in the root `nginx.conf`, keep in mind that these configurations must be enclosed inside a `http { }` block.
And do not forget to reload nginx with `systemctl reload nginx` or `nginx -s reload`.
### Exposing the S3 endpoints
First, we need to tell to nginx how to access our Garage cluster.
Because we have multiple nodes, we want to leverage all of them by spreading the load.
In nginx, we can do that with the `upstream` directive.
Then in a `server` directive, we define the vhosts, the TLS certificates and the proxy rule.
A possible configuration:
```nginx
upstream s3_backend {
# If you have a garage instance locally.
server 127.0.0.1:3900;
# You can also put your other instances.
server 192.168.1.3:3900;
# Domain names also work.
server garage1.example.com:3900;
# A "backup" server is only used if all others have failed.
server garage-remote.example.com:3900 backup;
# You can assign weights if you have some servers
# that can serve more requests than others.
server garage2.example.com:3900 weight=2;
}
server {
listen [::]:443 http2 ssl;
ssl_certificate /tmp/garage.crt;
ssl_certificate_key /tmp/garage.key;
# You need multiple server names here:
# - s3.garage.tld is used for path-based s3 requests
# - *.s3.garage.tld is used for vhost-based s3 requests
server_name s3.garage.tld *.s3.garage.tld;
location / {
proxy_pass http://s3_backend;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
# Disable buffering to a temporary file.
proxy_max_temp_file_size 0;
}
}
```
### Exposing the web endpoint
To better understand the logic involved, you can refer to the [Exposing buckets as websites](/cookbook/exposing_websites.html) section.
Otherwise, the configuration is very similar to the S3 endpoint.
You must only adapt `upstream` with the web port instead of the s3 port and change the `server_name` and `proxy_pass` entry
A possible configuration:
```nginx
upstream web_backend {
server 127.0.0.1:3902;
server 192.168.1.3:3902;
server garage1.example.com:3902;
server garage2.example.com:3902 weight=2;
}
server {
listen [::]:443 http2 ssl;
ssl_certificate /tmp/garage.crt;
ssl_certificate_key /tmp/garage.key;
# You need multiple server names here:
# - *.web.garage.tld is used for your users wanting a website without reserving a domain name
# - example.com, my-site.tld, etc. are reserved domain name by your users that chose to host their website as a garage's bucket
server_name *.web.garage.tld example.com my-site.tld;
location / {
proxy_pass http://web_backend;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
}
}
```
## Apache httpd
@TODO
## Traefik v2
We will see in this part how to set up a reverse proxy with [Traefik](https://docs.traefik.io/).
Here is [a basic configuration file](https://doc.traefik.io/traefik/https/acme/#configuration-examples):
```toml
[entryPoints]
[entryPoints.web]
address = ":80"
[entryPoints.websecure]
address = ":443"
[certificatesResolvers.myresolver.acme]
email = "your-email@example.com"
storage = "acme.json"
[certificatesResolvers.myresolver.acme.httpChallenge]
# used during the challenge
entryPoint = "web"
```
### Add Garage service
To add Garage on Traefik you should declare a new service using its IP address (or hostname) and port:
```toml
[http.services]
[http.services.my_garage_service.loadBalancer]
[[http.services.my_garage_service.loadBalancer.servers]]
url = "http://xxx.xxx.xxx.xxx"
port = 3900
```
It's possible to declare multiple Garage servers as back-ends:
```toml
[http.services]
[[http.services.my_garage_service.loadBalancer.servers]]
url = "http://xxx.xxx.xxx.xxx"
port = 3900
[[http.services.my_garage_service.loadBalancer.servers]]
url = "http://yyy.yyy.yyy.yyy"
port = 3900
[[http.services.my_garage_service.loadBalancer.servers]]
url = "http://zzz.zzz.zzz.zzz"
port = 3900
```
Traefik can remove unhealthy servers automatically with [a health check configuration](https://doc.traefik.io/traefik/routing/services/#health-check):
```
[http.services]
[http.services.my_garage_service.loadBalancer]
[http.services.my_garage_service.loadBalancer.healthCheck]
path = "/"
interval = "60s"
timeout = "5s"
```
### Adding a website
To add a new website, add the following declaration to your Traefik configuration file:
```toml
[http.routers]
[http.routers.my_website]
rule = "Host(`yoururl.example.org`)"
service = "my_garage_service"
entryPoints = ["web"]
```
Enable HTTPS access to your website with the following configuration section ([documentation](https://doc.traefik.io/traefik/https/overview/)):
```toml
...
entryPoints = ["websecure"]
[http.routers.my_website.tls]
certResolver = "myresolver"
...
```
### Adding gzip compression
Add the following configuration section [to compress response](https://doc.traefik.io/traefik/middlewares/http/compress/) using [gzip](https://developer.mozilla.org/en-US/docs/Glossary/GZip_compression) before sending them to the client:
```toml
[http.routers]
[http.routers.my_website]
...
middlewares = ["gzip_compress"]
...
[http.middlewares]
[http.middlewares.gzip_compress.compress]
```
### Add caching response
Traefik's caching middleware is only available on [entreprise version](https://doc.traefik.io/traefik-enterprise/middlewares/http-cache/), however the freely-available [Souin plugin](https://github.com/darkweak/souin#tr%C3%A6fik-container) can also do the job. (section to be completed)
### Complete example
```toml
[entryPoints]
[entryPoints.web]
address = ":80"
[entryPoints.websecure]
address = ":443"
[certificatesResolvers.myresolver.acme]
email = "your-email@example.com"
storage = "acme.json"
[certificatesResolvers.myresolver.acme.httpChallenge]
# used during the challenge
entryPoint = "web"
[http.routers]
[http.routers.my_website]
rule = "Host(`yoururl.example.org`)"
service = "my_garage_service"
middlewares = ["gzip_compress"]
entryPoints = ["websecure"]
[http.services]
[http.services.my_garage_service.loadBalancer]
[http.services.my_garage_service.loadBalancer.healthCheck]
path = "/"
interval = "60s"
timeout = "5s"
[[http.services.my_garage_service.loadBalancer.servers]]
url = "http://xxx.xxx.xxx.xxx"
[[http.services.my_garage_service.loadBalancer.servers]]
url = "http://yyy.yyy.yyy.yyy"
[[http.services.my_garage_service.loadBalancer.servers]]
url = "http://zzz.zzz.zzz.zzz"
[http.middlewares]
[http.middlewares.gzip_compress.compress]
```
## Caddy
Your Caddy configuration can be as simple as:
```caddy
s3.garage.tld, *.s3.garage.tld {
reverse_proxy localhost:3900 192.168.1.2:3900 example.tld:3900
}
*.web.garage.tld {
reverse_proxy localhost:3902 192.168.1.2:3900 example.tld:3900
}
admin.garage.tld {
reverse_proxy localhost:3903
}
```
But at the same time, the `reverse_proxy` is very flexible.
For a production deployment, you should [read its documentation](https://caddyserver.com/docs/caddyfile/directives/reverse_proxy) as it supports features like DNS discovery of upstreams, load balancing with checks, streaming parameters, etc.

title = "Upgrading Garage"
weight = 60
+++
Garage is a stateful clustered application, where all nodes are communicating together and share data structures.
It makes upgrade more difficult than stateless applications so you must be more careful when upgrading.
On a new version release, there is 2 possibilities:
- protocols and data structures remained the same ➡️ this is a **straightforward upgrade**
- protocols or data structures changed ➡️ this is an **advanced upgrade**
You can quickly now what type of update you will have to operate by looking at the version identifier.
Following the [SemVer ](https://semver.org/) terminology, if only the *patch* number changed, it will only need a straightforward upgrade.
Example: an upgrade from v0.6.0 from v0.6.1 is a straightforward upgrade.
If the *minor* or *major* number changed however, you will have to do an advanced upgrade. Example: from v0.6.1 to v0.7.0.
Migrations are designed to be run only between contiguous versions (from a *major*.*minor* perspective, *patches* can be skipped).
Example: migrations from v0.6.1 to v0.7.0 and from v0.6.0 to v0.7.0 are supported but migrations from v0.5.0 to v0.7.0 are not supported.
## Straightforward upgrades
Straightforward upgrades do not imply cluster downtime.
Before upgrading, you should still read [the changelog](https://git.deuxfleurs.fr/Deuxfleurs/garage/releases) and ideally test your deployment on a staging cluster before.
When you are ready, start by checking the health of your cluster.
You can force some checks with `garage repair`, we recommend at least running `garage repair --all-nodes --yes` that is very quick to run (less than a minute).
You will see that the command correctly terminated in the logs of your daemon.
Finally, you can simply upgrades nodes one by one.
For each node: stop it, install the new binary, edit the configuration if needed, restart it.
## Advanced upgrades
Advanced upgrades will imply cluster downtime.
Before upgrading, you must read [the changelog](https://git.deuxfleurs.fr/Deuxfleurs/garage/releases) and you must test your deployment on a staging cluster before.
From a high level perspective, an advanced upgrade looks like this:
1. Make sure the health of your cluster is good (see `garage repair`)
2. Disable API access (comment the configuration in your reverse proxy)
3. Check that your cluster is idle
4. Stop the whole cluster
5. Backup the metadata folder of all your nodes, so that you will be able to restore it quickly if the upgrade fails (blocks being immutable, they should not be impacted)
6. Install the new binary, update the configuration
7. Start the whole cluster
8. If needed, run the corresponding migration from `garage migrate`
9. Make sure the health of your cluster is good
10. Enable API access (uncomment the configuration in your reverse proxy)
11. Monitor your cluster while load comes back, check that all your applications are happy with this new version
We write guides for each advanced upgrade, they are stored under the "Working Documents" section of this documentation.

title = "Administration API"
weight = 60
+++
The Garage administration API is accessible through a dedicated server whose
listen address is specified in the `[admin]` section of the configuration
file (see [configuration file
reference](@/documentation/reference-manual/configuration.md))
**WARNING.** At this point, there is no comittement to stability of the APIs described in this document.
We will bump the version numbers prefixed to each API endpoint at each time the syntax
or semantics change, meaning that code that relies on these endpoint will break
when changes are introduced.
The Garage administration API was introduced in version 0.7.2, this document
does not apply to older versions of Garage.
## Access control
The admin API uses two different tokens for acces control, that are specified in the config file's `[admin]` section:
- `metrics_token`: the token for accessing the Metrics endpoint (if this token
is not set in the config file, the Metrics endpoint can be accessed without
access control);
- `admin_token`: the token for accessing all of the other administration
endpoints (if this token is not set in the config file, access to these
endpoints is disabled entirely).
These tokens are used as simple HTTP bearer tokens. In other words, to
authenticate access to an admin API endpoint, add the following HTTP header
to your request:
```
Authorization: Bearer <token>
```
## Administration API endpoints
### Metrics-related endpoints
#### Metrics `GET /metrics`
Returns internal Garage metrics in Prometheus format.
### Cluster operations
These endpoints are defined on a dedicated [Redocly page](https://garagehq.deuxfleurs.fr/api/garage-admin-v0.html). You can also download its [OpenAPI specification](https://garagehq.deuxfleurs.fr/api/garage-admin-v0.yml).
Requesting the API from the command line can be as simple as running:
```bash
curl -H 'Authorization: Bearer s3cr3t' http://localhost:3903/v0/status | jq
```
For more advanced use cases, we recommend using a SDK.

```
The following gives details about each available configuration option.
## Available configuration options
### `metadata_dir`
The directory in which Garage will store its metadata. This contains the node identifier,
the network configuration and the peer list, the list of buckets and keys as well
as the index of all objects, object version and object blocks.
Store this folder on a fast SSD drive if possible to maximize Garage's performance.
### `data_dir`
The directory in which Garage will store the data blocks of objects.
This folder can be placed on an HDD. The space available for `data_dir`
should be counted to determine a node's capacity
when [adding it to the cluster layout](@/documentation/cookbook/real-world.md).
### `db_engine` (since `v0.8.0`)
By default, Garage uses the Sled embedded database library
to store its metadata on-disk. Since `v0.8.0`, Garage can use alternative storage backends as follows:
| DB engine | `db_engine` value | Database path |
| --------- | ----------------- | ------------- |
| [Sled](https://sled.rs) | `"sled"` | `<metadata_dir>/db/` |
| [LMDB](https://www.lmdb.tech) | `"lmdb"` | `<metadata_dir>/db.lmdb/` |
| [Sqlite](https://sqlite.org) | `"sqlite"` | `<metadata_dir>/db.sqlite` |
Performance characteristics of the different DB engines are as follows:
- Sled: the default database engine, which tends to produce
large data files and also has performance issues, especially when the metadata folder
is on a traditionnal HDD and not on SSD.
- LMDB: the recommended alternative on 64-bit systems,
much more space-efficiant and slightly faster. Note that the data format of LMDB is not portable
between architectures, so for instance the Garage database of an x86-64
node cannot be moved to an ARM64 node. Also note that, while LMDB can technically be used on 32-bit systems,
this will limit your node to very small database sizes due to how LMDB works; it is therefore not recommended.
- Sqlite: Garage supports Sqlite as a storage backend for metadata,
however it may have issues and is also very slow in its current implementation,
so it is not recommended to be used for now.
It is possible to convert Garage's metadata directory from one format to another with a small utility named `convert_db`,
which can be downloaded at the following locations:
[for amd64](https://garagehq.deuxfleurs.fr/_releases/convert_db/amd64/convert_db),
[for i386](https://garagehq.deuxfleurs.fr/_releases/convert_db/i386/convert_db),
[for arm64](https://garagehq.deuxfleurs.fr/_releases/convert_db/arm64/convert_db),
[for arm](https://garagehq.deuxfleurs.fr/_releases/convert_db/arm/convert_db).
The `convert_db` utility is used as folows:
```
convert-db -a <input db engine> -i <input db path> \
-b <output db engine> -o <output db path>
```
Make sure to specify the full database path as presented in the table above,
and not just the path to the metadata directory.
### `block_size`
Garage splits stored objects in consecutive chunks of size `block_size`
(except the last one which might be smaller). The default size is 1MB and
should work in most cases. We recommend increasing it to e.g. 10MB if
you are using Garage to store large files and have fast network connections
between all nodes (e.g. 1gbps).
If you are interested in tuning this, feel free to do so (and remember to
report your findings to us!). When this value is changed for a running Garage
installation, only files newly uploaded will be affected. Previously uploaded
files will remain available. This however means that chunks from existing files
will not be deduplicated with chunks from newly uploaded files, meaning you
might use more storage space that is optimally possible.
### `sled_cache_capacity`
This parameter can be used to tune the capacity of the cache used by
[sled](https://sled.rs), the database Garage uses internally to store metadata.
Tune this to fit the RAM you wish to make available to your Garage instance.
This value has a conservative default (128MB) so that Garage doesn't use too much
RAM by default, but feel free to increase this for higher performance.
### `sled_flush_every_ms`
This parameters can be used to tune the flushing interval of sled.
Increase this if sled is thrashing your SSD, at the risk of losing more data in case
of a power outage (though this should not matter much as data is replicated on other
nodes). The default value, 2000ms, should be appropriate for most use cases.
### `replication_mode`
Garage supports the following replication modes:
- `none` or `1`: data stored on Garage is stored on a single node. There is no
redundancy, and data will be unavailable as soon as one node fails or its
network is disconnected. Do not use this for anything else than test
deployments.
- `2`: data stored on Garage will be stored on two different nodes, if possible
in different zones. Garage tolerates one node failure, or several nodes
failing but all in a single zone (in a deployment with at least two zones),
before losing data. Data remains available in read-only mode when one node is
down, but write operations will fail.
- `2-dangerous`: a variant of mode `2`, where written objects are written to
the second replica asynchronously. This means that Garage will return `200
OK` to a PutObject request before the second copy is fully written (or even
before it even starts being written). This means that data can more easily
be lost if the node crashes before a second copy can be completed. This
also means that written objects might not be visible immediately in read
operations. In other words, this mode severely breaks the consistency and
durability guarantees of standard Garage cluster operation. Benefits of
this mode: you can still write to your cluster when one node is
unavailable.
- `3`: data stored on Garage will be stored on three different nodes, if
possible each in a different zones. Garage tolerates two node failure, or
several node failures but in no more than two zones (in a deployment with at
least three zones), before losing data. As long as only a single node fails,
or node failures are only in a single zone, reading and writing data to
Garage can continue normally.
- `3-degraded`: a variant of replication mode `3`, that lowers the read
quorum to `1`, to allow you to read data from your cluster when several
nodes (or nodes in several zones) are unavailable. In this mode, Garage
does not provide read-after-write consistency anymore. The write quorum is
still 2, ensuring that data successfully written to Garage is stored on at
least two nodes.
- `3-dangerous`: a variant of replication mode `3` that lowers both the read
and write quorums to `1`, to allow you to both read and write to your
cluster when several nodes (or nodes in several zones) are unavailable. It
is the least consistent mode of operation proposed by Garage, and also one
that should probably never be used.
Note that in modes `2` and `3`,
if at least the same number of zones are available, an arbitrary number of failures in
any given zone is tolerated as copies of data will be spread over several zones.
**Make sure `replication_mode` is the same in the configuration files of all nodes.
Never run a Garage cluster where that is not the case.**
The quorums associated with each replication mode are described below:
| `replication_mode` | Number of replicas | Write quorum | Read quorum | Read-after-write consistency? |
| ------------------ | ------------------ | ------------ | ----------- | ----------------------------- |
| `none` or `1` | 1 | 1 | 1 | yes |
| `2` | 2 | 2 | 1 | yes |
| `2-dangerous` | 2 | 1 | 1 | NO |
| `3` | 3 | 2 | 2 | yes |
| `3-degraded` | 3 | 2 | 1 | NO |
| `3-dangerous` | 3 | 1 | 1 | NO |
Changing the `replication_mode` between modes with the same number of replicas
(e.g. from `3` to `3-degraded`, or from `2-dangerous` to `2`), can be done easily by
just changing the `replication_mode` parameter in your config files and restarting all your
Garage nodes.
It is also technically possible to change the replication mode to a mode with a
different numbers of replicas, although it's a dangerous operation that is not
officially supported. This requires you to delete the existing cluster layout
and create a new layout from scratch, meaning that a full rebalancing of your
cluster's data will be needed. To do it, shut down your cluster entirely,
delete the `custer_layout` files in the meta directories of all your nodes,
update all your configuration files with the new `replication_mode` parameter,
restart your cluster, and then create a new layout with all the nodes you want
to keep. Rebalancing data will take some time, and data might temporarily
appear unavailable to your users. It is recommended to shut down public access
to the cluster while rebalancing is in progress. In theory, no data should be
lost as rebalancing is a routine operation for Garage, although we cannot
guarantee you that everything will go right in such an extreme scenario.
### `compression_level`
Zstd compression level to use for storing blocks.
Values between `1` (faster compression) and `19` (smaller file) are standard compression
levels for zstd. From `20` to `22`, compression levels are referred as "ultra" and must be
used with extra care as it will use lot of memory. A value of `0` will let zstd choose a
default value (currently `3`). Finally, zstd has also compression designed to be faster
than default compression levels, they range from `-1` (smaller file) to `-99` (faster
compression).
If you do not specify a `compression_level` entry, Garage will set it to `1` for you. With
this parameters, zstd consumes low amount of cpu and should work faster than line speed in
most situations, while saving some space and intra-cluster
bandwidth.
If you want to totally deactivate zstd in Garage, you can pass the special value `'none'`. No
zstd related code will be called, your chunks will be stored on disk without any processing.
Compression is done synchronously, setting a value too high will add latency to write queries.
This value can be different between nodes, compression is done by the node which receive the
API call.
### `rpc_secret`
Garage uses a secret key that is shared between all nodes of the cluster
in order to identify these nodes and allow them to communicate together.
This key should be specified here in the form of a 32-byte hex-encoded
random string. Such a string can be generated with a command
such as `openssl rand -hex 32`.
### `rpc_bind_addr`
The address and port on which to bind for inter-cluster communcations
(reffered to as RPC for remote procedure calls).
The port specified here should be the same one that other nodes will used to contact
the node, even in the case of a NAT: the NAT should be configured to forward the external
port number to the same internal port nubmer. This means that if you have several nodes running
behind a NAT, they should each use a different RPC port number.
### `rpc_public_addr`
The address and port that other nodes need to use to contact this node for
RPC calls. **This parameter is optional but recommended.** In case you have
a NAT that binds the RPC port to a port that is different on your public IP,
this field might help making it work.
### `bootstrap_peers`
A list of peer identifiers on which to contact other Garage peers of this cluster.
These peer identifiers have the following syntax:
```
<node public key>@<node public IP or hostname>:<port>
```
In the case where `rpc_public_addr` is correctly specified in the
configuration file, the full identifier of a node including IP and port can
be obtained by running `garage node id` and then included directly in the
`bootstrap_peers` list of other nodes. Otherwise, only the node's public
key will be returned by `garage node id` and you will have to add the IP
yourself.
## The `[consul_discovery]` section
Garage supports discovering other nodes of the cluster using Consul. For this
to work correctly, nodes need to know their IP address by which they can be
reached by other nodes of the cluster, which should be set in `rpc_public_addr`.
### `consul_http_addr` and `service_name`
The `consul_http_addr` parameter should be set to the full HTTP(S) address of the Consul server.
### `service_name`
`service_name` should be set to the service name under which Garage's
RPC ports are announced.
### `client_cert`, `client_key`
TLS client certificate and client key to use when communicating with Consul over TLS. Both are mandatory when doing so.
### `ca_cert`
TLS CA certificate to use when communicating with Consul over TLS.
### `tls_skip_verify`
Skip server hostname verification in TLS handshake.
`ca_cert` is ignored when this is set.
## The `[kubernetes_discovery]` section
Garage supports discovering other nodes of the cluster using kubernetes custom
resources. For this to work, a `[kubernetes_discovery]` section must be present
with at least the `namespace` and `service_name` parameters.
### `namespace`
`namespace` sets the namespace in which the custom resources are
configured.
### `service_name`
`service_name` is added as a label to the advertised resources to
filter them, to allow for multiple deployments in a single namespace.
### `skip_crd`
`skip_crd` can be set to true to disable the automatic creation and
patching of the `garagenodes.deuxfleurs.fr` CRD. You will need to create the CRD
manually.
## The `[s3_api]` section
### `api_bind_addr`
The IP and port on which to bind for accepting S3 API calls.
This endpoint does not suport TLS: a reverse proxy should be used to provide it.
### `s3_region`
Garage will accept S3 API calls that are targetted to the S3 region defined here.
API calls targetted to other regions will fail with a AuthorizationHeaderMalformed error
message that redirects the client to the correct region.
### `root_domain` {#root_domain}
The optionnal suffix to access bucket using vhost-style in addition to path-style request.
Note path-style requests are always enabled, whether or not vhost-style is configured.
Configuring vhost-style S3 required a wildcard DNS entry, and possibly a wildcard TLS certificate,
but might be required by softwares not supporting path-style requests.
If `root_domain` is `s3.garage.eu`, a bucket called `my-bucket` can be interacted with
using the hostname `my-bucket.s3.garage.eu`.
## The `[s3_web]` section
Garage allows to publish content of buckets as websites. This section configures the
behaviour of this module.
### `bind_addr`
The IP and port on which to bind for accepting HTTP requests to buckets configured
for website access.
This endpoint does not suport TLS: a reverse proxy should be used to provide it.
### `root_domain`
The optionnal suffix appended to bucket names for the corresponding HTTP Host.
For instance, if `root_domain` is `web.garage.eu`, a bucket called `deuxfleurs.fr`
will be accessible either with hostname `deuxfleurs.fr.web.garage.eu`
or with hostname `deuxfleurs.fr`.
## The `[admin]` section
Garage has a few administration capabilities, in particular to allow remote monitoring. These features are detailed below.
### `api_bind_addr`
If specified, Garage will bind an HTTP server to this port and address, on
which it will listen to requests for administration features.
See [administration API reference](@/documentation/reference-manual/admin-api.md) to learn more about these features.
### `metrics_token` (since version 0.7.2)
The token for accessing the Metrics endpoint. If this token is not set in
the config file, the Metrics endpoint can be accessed without access
control.
You can use any random string for this value. We recommend generating a random token with `openssl rand -hex 32`.
### `admin_token` (since version 0.7.2)
The token for accessing all of the other administration endpoints. If this
token is not set in the config file, access to these endpoints is disabled
entirely.
You can use any random string for this value. We recommend generating a random token with `openssl rand -hex 32`.
### `trace_sink`
Optionnally, the address of an Opentelemetry collector. If specified,
Garage will send traces in the Opentelemetry format to this endpoint. These
trace allow to inspect Garage's operation when it handles S3 API requests.

### S3 API
The main goal of Garage is to provide an object storage service that is compatible with the
[S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html) from Amazon Web Services.
We try to adhere as strictly as possible to the semantics of the API as implemented by Amazon
and other vendors such as Minio or CEPH.
Of course Garage does not implement the full span of API endpoints that AWS S3 does;
the exact list of S3 features implemented by Garage can be found [on our S3 compatibility page](@/documentation/reference-manual/s3-compatibility.md).
### Geo-distribution
Garage allows you to store copies of your data in multiple geographical locations in order to maximize resilience
to adverse events, such as network/power outages or hardware failures.
This allows Garage to run very well even at home, using consumer-grade Internet connectivity
(such as FTTH) and power, as long as cluster nodes can be spawned at several physical locations.
Garage exploits knowledge of the capacity and physical location of each storage node to design
a storage plan that best exploits the available storage capacity while satisfying the geo-distributed replication constraint.
To learn more about geo-distributed Garage clusters,
read our documentation on [setting up a real-world deployment](@/documentation/cookbook/real-world.md).
### Standalone/self-contained
Garage is extremely simple to deploy, and does not depend on any external service to run.
This makes setting up and administering storage clusters, we hope, as easy as it could be.
### Flexible topology
A Garage cluster can very easily evolve over time, as storage nodes are added or removed.
Garage will automatically rebalance data between nodes as needed to ensure the desired number of copies.
Read about cluster layout management [here](@/documentation/reference-manual/layout.md).
### No RAFT slowing you down
It might seem strange to tout the absence of something as a desirable feature,
but this is in fact a very important point! Garage does not use RAFT or another
consensus algorithm internally to order incoming requests: this means that all requests
directed to a Garage cluster can be handled independently of one another instead
of going through a central bottleneck (the leader node).
As a consequence, requests can be handled much faster, even in cases where latency
between cluster nodes is important (see our [benchmarks](@/documentation/design/benchmarks/index.md) for data on this).
This is particularly usefull when nodes are far from one another and talk to one other through standard Internet connections.
### Several replication modes
Garage supports a variety of replication modes, with 1 copy, 2 copies or 3 copies of your data,
and with various levels of consistency, in order to adapt to a variety of usage scenarios.
Read our reference page on [supported replication modes](@/documentation/reference-manual/configuration.md#replication-mode)
to select the replication mode best suited to your use case (hint: in most cases, `replication_mode = "3"` is what you want).
### Web server for static websites
A storage bucket can easily be configured to be served directly by Garage as a static web site.
Domain names for multiple websites directly map to bucket names, making it easy to build
a platform for your users to autonomously build and host their websites over Garage.
Surprisingly, none of the other alternative S3 implementations we surveyed (such as Minio
or CEPH) support publishing static websites from S3 buckets, a feature that is however
directly inherited from S3 on AWS.
Read more on our [dedicated documentation page](@/documentation/cookbook/exposing-websites.md).
### Bucket names as aliases
In Garage, a bucket may have several names, known as aliases.
Aliases can easily be added and removed on demand:
this allows to easily rename buckets if needed
without having to copy all of their content, something that cannot be done on AWS.
For buckets served as static websites, having multiple aliases for a bucket can allow
exposing the same content under different domain names.
Garage also supports bucket aliases which are local to a single user:
this allows different users to have different buckets with the same name, thus avoiding naming collisions.
This can be helpfull for instance if you want to write an application that creates per-user buckets with always the same name.
This feature is totally invisible to S3 clients and does not break compatibility with AWS.
### Cluster administration API
Garage provides a fully-fledged REST API to administer your cluster programatically.
Functionality included in the admin API include: setting up and monitoring
cluster nodes, managing access credentials, and managing storage buckets and bucket aliases.
A full reference of the administration API is available [here](@/documentation/reference-manual/admin-api.md).
### Metrics and traces
Garage makes some internal metrics available in the Prometheus data format,
which allows you to build interactive dashboards to visualize the load and internal state of your storage cluster.
For developpers and performance-savvy administrators,
Garage also supports exporting traces of what it does internally in OpenTelemetry format.
This allows to monitor the time spent at various steps of the processing of requests,
in order to detect potential performance bottlenecks.
### Kubernetes and Nomad integrations
Garage can automatically discover other nodes in the cluster thanks to integration
with orchestrators such as Kubernetes and Nomad (when used with Consul).
This eases the configuration of your cluster as it removes one step where nodes need
to be manually connected to one another.
### Support for changing IP addresses
As long as all of your nodes don't change their IP address at the same time,
Garage should be able to tolerate nodes with changing/dynamic IP addresses,
as nodes will regularly exchange the IP addresses of their peers and try to
reconnect using newer addresses when existing connections are broken.
### K2V API (experimental)
As part of an ongoing research project, Garage can expose an experimental key/value storage API called K2V.
K2V is made for the storage and retrieval of many small key/value pairs that need to be processed in bulk.
This completes the S3 API with an alternative that can be used to easily store and access metadata
related to objects stored in an S3 bucket.
In the context of our research project, [Aérogramme](https://aerogramme.deuxfleurs.fr),
K2V is used to provide metadata and log storage for operations on encrypted e-mail storage.
Learn more on the specification of K2V [here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/k2v/doc/drafts/k2v-spec.md)
and on how to enable it in Garage [here](@/documentation/reference-manual/k2v.md).

+++
Starting with version 0.7.2, Garage introduces an optionnal feature, K2V,
which is an alternative storage API designed to help efficiently store
many small values in buckets (in opposition to S3 which is more designed
to store large blobs).
K2V is currently disabled at compile time in all builds, as the
specification is still subject to changes. To build a Garage version with
K2V, the Cargo feature flag `k2v` must be activated. Special builds with
the `k2v` feature flag enabled can be obtained from our download page under
"Extra builds": such builds can be identified easily as their tag name ends
with `-k2v` (example: `v0.7.2-k2v`).
The specification of the K2V API can be found
[here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/k2v/doc/drafts/k2v-spec.md).
This document also includes a high-level overview of K2V's design.
The K2V API uses AWSv4 signatures for authentification, same as the S3 API.
The AWS region used for signature calculation is always the same as the one
defined for the S3 API in the config file.
## Enabling and using K2V
To enable K2V, download and run a build that has the `k2v` feature flag
enabled, or produce one yourself. Then, add the following section to your
configuration file:
```toml
[k2v_api]
api_bind_addr = "<ip>:<port>"
```
Please select a port number that is not already in use by another API
endpoint (S3 api, admin API) or by the RPC server.
We provide an early-stage K2V client library for Rust which can be imported by adding the following to your `Cargo.toml` file:
```toml
k2v-client = { git = "https://git.deuxfleurs.fr/Deuxfleurs/garage.git" }
```
There is also a simple CLI utility which can be built from source in the
following way:
```sh
git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
cd garage/src/k2v-client
cargo build --features cli --bin k2v-cli
```
The CLI utility is self-documented, run `k2v-cli --help` to learn how to use
it. There is also a short README.md in the `src/k2v-client` folder with some
instructions.

| [Presigned URLs](https://docs.aws.amazon.com/AmazonS3/latest/userguide/ShareObjectPreSignedURL.html) | ✅ Implemented | ❌| ✅ | ✅ | ✅(❓) |
*Note:* OpenIO does not says if it supports presigned URLs. Because it is part
of signature v4 and they claim they support it without additional precisions,
we suppose that OpenIO supports presigned URLs.
## Endpoint implementation
All endpoints that are missing on Garage will return a 501 Not Implemented.
Some `x-amz-` headers are not implemented.
### Core endoints
| Endpoint | Garage | [Openstack Swift](https://docs.openstack.org/swift/latest/s3_compat.html) | [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/s3/) | [Riak CS](https://docs.riak.com/riak/cs/2.1.1/references/apis/storage/s3/index.html) | [OpenIO](https://docs.openio.io/latest/source/arch-design/s3_compliancy.html) |
|------------------------------|----------------------------------|-----------------|---------------|---------|-----|
| [CreateBucket](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateBucket.html) | ✅ Implemented | ✅ | ✅ | ✅ | ✅ |

| [ListBuckets](https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListBuckets.html) | ✅ Implemented | ❌| ✅ | ✅ | ✅ |
| [HeadObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_HeadObject.html) | ✅ Implemented | ✅ | ✅ | ✅ | ✅ |
| [CopyObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CopyObject.html) | ✅ Implemented | ✅ | ✅ | ✅ | ✅ |
| [DeleteObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteObject.html) | ✅ Implemented | ✅ | ✅ | ✅ | ✅ |
| [DeleteObjects](https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteObjects.html) | ✅ Implemented | ✅ | ✅ | ✅ | ✅ |
| [GetObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html) | ✅ Implemented | ✅ | ✅ | ✅ | ✅ |
| [ListObjects](https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjects.html) | ✅ Implemented (see details below) | ✅ | ✅ | ✅ | ❌|

| [PutObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutObject.html) | ✅ Implemented | ✅ | ✅ | ✅ | ✅ |
**ListObjects:** Implemented, but there isn't a very good specification of what
`encoding-type=url` covers so there might be some encoding bugs. In our
implementation the url-encoded fields are in the same in ListObjects as they
are in ListObjectsV2.
*Note: Ceph API documentation is incomplete and lacks at least HeadBucket and UploadPartCopy,
but these endpoints are documented in [Red Hat Ceph Storage - Chapter 2. Ceph Object Gateway and the S3 API](https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/4/html/developer_guide/ceph-object-gateway-and-the-s3-api)*
### Multipart Upload endpoints
| Endpoint | Garage | [Openstack Swift](https://docs.openstack.org/swift/latest/s3_compat.html) | [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/s3/) | [Riak CS](https://docs.riak.com/riak/cs/2.1.1/references/apis/storage/s3/index.html) | [OpenIO](https://docs.openio.io/latest/source/arch-design/s3_compliancy.html) |
|------------------------------|----------------------------------|-----------------|---------------|---------|-----|

| [UploadPartCopy](https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPartCopy.html) | ✅ Implemented | ✅ | ✅ | ✅ | ✅ |
Our implementation of Multipart Upload is currently a bit more restrictive than Amazon's one in some edge cases.
For more information, please refer to our [issue tracker](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/204).
### Website endpoints
| Endpoint | Garage | [Openstack Swift](https://docs.openstack.org/swift/latest/s3_compat.html) | [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/s3/) | [Riak CS](https://docs.riak.com/riak/cs/2.1.1/references/apis/storage/s3/index.html) | [OpenIO](https://docs.openio.io/latest/source/arch-design/s3_compliancy.html) |
|------------------------------|----------------------------------|-----------------|---------------|---------|-----|
| [DeleteBucketWebsite](https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteBucketWebsite.html) | ✅ Implemented | ❌| ❌| ❌| ❌|
| [GetBucketWebsite](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketWebsite.html) | ✅ Implemented | ❌ | ❌| ❌| ❌|
| [PutBucketWebsite](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketWebsite.html) | ⚠ Partially implemented (see below)| ❌| ❌| ❌| ❌|
| [DeleteBucketCors](https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteBucketCors.html) | ✅ Implemented | ❌| ✅ | ❌| ✅ |

| [PutBucketCors](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketCors.html) | ✅ Implemented | ❌| ✅ | ❌| ✅ |
**PutBucketWebsite:** Implemented, but only stores the index document suffix and the error document path. Redirects are not supported.
*Note: Ceph radosgw has some support for static websites but it is different from the Amazon one. It also does not implement its configuration endpoints.*
### ACL, Policies endpoints
Amazon has 2 access control mechanisms in S3: ACL (legacy) and policies (new one).
Garage implements none of them, and has its own system instead, built around a per-access-key-per-bucket logic.
See Garage CLI reference manual to learn how to use Garage's permission system.

| [PutObjectAcl](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutObjectAcl.html) | ❌ Missing | ✅ | ✅ | ✅ | ✅ |
*Notes:* Riak CS only supports a subset of the policy configuration.
### Versioning, Lifecycle endpoints
Garage does not (yet) support object versioning.
If you need this feature, please [share your use case in our dedicated issue](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/166).
| Endpoint | Garage | [Openstack Swift](https://docs.openstack.org/swift/latest/s3_compat.html) | [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/s3/) | [Riak CS](https://docs.riak.com/riak/cs/2.1.1/references/apis/storage/s3/index.html) | [OpenIO](https://docs.openio.io/latest/source/arch-design/s3_compliancy.html) |

| [PutBucketVersioning](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketVersioning.html) | ❌ Missing | ❌| ✅| ❌| ✅|
**GetBucketVersioning:** Stub implementation (Garage does not yet support versionning so this always returns "versionning not enabled").
### Replication endpoints
Please open an issue if you have a use case for replication.
| Endpoint | Garage | [Openstack Swift](https://docs.openstack.org/swift/latest/s3_compat.html) | [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/s3/) | [Riak CS](https://docs.riak.com/riak/cs/2.1.1/references/apis/storage/s3/index.html) | [OpenIO](https://docs.openio.io/latest/source/arch-design/s3_compliancy.html) |

| [PutBucketReplication](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketReplication.html) | ❌ Missing | ❌| ⚠ | ❌| ❌|
*Note: Ceph documentation briefly says that Ceph supports
[replication through the S3 API](https://docs.ceph.com/en/latest/radosgw/multisite-sync-policy/#s3-replication-api)
but with some limitations.
Additionaly, replication endpoints are not documented in the S3 compatibility page so I don't know what kind of support we can expect.*
### Locking objects
Amazon defines a concept of [object locking](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-lock.html) that can be achieved either through a Retention period or a Legal hold.

### (Server-side) encryption
We think that you can either encrypt your server partition or do client-side encryption, so we did not implement server-side encryption for Garage.
Please open an issue if you have a use case.
| Endpoint | Garage | [Openstack Swift](https://docs.openstack.org/swift/latest/s3_compat.html) | [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/s3/) | [Riak CS](https://docs.riak.com/riak/cs/2.1.1/references/apis/storage/s3/index.html) | [OpenIO](https://docs.openio.io/latest/source/arch-design/s3_compliancy.html) |

In return, this system is a bit harder to configure.
We show how it is still possible to configure Garage with Peertube, allowing you to spread the load and the bandwidth usage on the Garage cluster.
Starting from version 5.0, Peertube also supports improving the security for private videos by not exposing them directly
but relying on a single control point in the Peertube instance. This is based on S3 per-object and prefix ACL, which are not currently supported
in Garage, so this feature is unsupported. While this technically impedes security for private videos, it is not a blocking issue and could be
a reasonable trade-off for some instances.

## Mastodon
Mastodon natively supports the S3 protocol to store media files, and it works out-of-the-box with Garage.
You will need to expose your Garage bucket as a website: that way, media files will be served directly from Garage.
### Performance considerations
Mastodon tends to store many small objects over time: expect hundreds of thousands of objects,
with average object size ranging from 50 KB to 150 KB.
As such, your Garage cluster should be configured appropriately for good performance:
- use Garage v0.8.0 or higher with the [LMDB database engine](@documentation/reference-manual/configuration.md#db-engine-since-v0-8-0).
With the default Sled database engine, your database could quickly end up taking tens of GB of disk space.
- the Garage database should be stored on a SSD
### Creating your bucket
This is the usual Garage setup:
```bash
garage key new --name mastodon-key
garage bucket create mastodon-data
garage bucket allow mastodon-data --read --write --key mastodon-key
```
Note the Key ID and Secret Key.
### Exposing your bucket as a website
Create a DNS name to serve your media files, such as `my-social-media.mydomain.tld`.
This name will be publicly exposed to the users of your Mastodon instance: they
will load images directly from this DNS name.
As [documented here](@/documentation/cookbook/exposing-websites.md),
add this DNS name as alias to your bucket, and expose it as a website:
```bash
garage bucket alias mastodon-data my-social-media.mydomain.tld
garage bucket website --allow mastodon-data
```
Then you will likely need to [setup a reverse proxy](@/documentation/cookbook/reverse-proxy.md)
in front of it to serve your media files over HTTPS.
### Cleaning up old media files before migration
Mastodon instance quickly accumulate a lot of media files from the federation.
Most of them are not strictly necessary because they can be fetched again from
other servers. As such, it is highly recommended to clean them up before
migration, this will greatly reduce the migration time.
From the [official Mastodon documentation](https://docs.joinmastodon.org/admin/tootctl/#media):
```bash
$ RAILS_ENV=production bin/tootctl media remove --days 3
$ RAILS_ENV=production bin/tootctl media remove-orphans
$ RAILS_ENV=production bin/tootctl preview_cards remove --days 15
```
Here is a typical disk usage for a small but multi-year instance after cleanup:
```bash
$ RAILS_ENV=production bin/tootctl media usage
Attachments: 5.67 GB (1.14 GB local)
Custom emoji: 295 MB (0 Bytes local)
Preview cards: 154 MB
Avatars: 3.77 GB (127 KB local)
Headers: 8.72 GB (242 KB local)
Backups: 0 Bytes
Imports: 1.7 KB
Settings: 0 Bytes
```
Unfortunately, [old avatars and headers cannot currently be cleaned up](https://github.com/mastodon/mastodon/issues/9567).
### Migrating your data
Data migration should be done with an efficient S3 client.
The [minio client](@documentation/connect/cli.md#minio-client) is a good choice
thanks to its mirror mode:
```bash
mc mirror ./public/system/ garage/mastodon-data
```
Here is a typical bucket usage after all data has been migrated:
```bash
$ garage bucket info mastodon-data
Size: 20.3 GiB (21.8 GB)
Objects: 175968
```
### Configuring Mastodon
In your `.env.production` configuration file:
```bash
S3_ENABLED=true
# Internal access to Garage
S3_ENDPOINT=http://my-garage-instance.mydomain.tld:3900
S3_REGION=garage
S3_BUCKET=mastodon-data
# Change this (Key ID and Secret Key of your Garage key)
AWS_ACCESS_KEY_ID=GKe88df__CHANGETHIS__c5145
AWS_SECRET_ACCESS_KEY=a2f7__CHANGETHIS__77fcfcf7a58f47a4aa4431f2e675c56da37821a1070000
# What name gets exposed to users (HTTPS is implicit)
S3_ALIAS_HOST=my-social-media.mydomain.tld
```
For more details, see the [reference Mastodon documentation](https://docs.joinmastodon.org/admin/config/#cdn).
Restart all Mastodon services and everything should now be using Garage!
You can check the URLs of images in the Mastodon web client, they should start
with `https://my-social-media.mydomain.tld`.
### Last migration sync
After Mastodon is successfully using Garage, you can run a last sync from the local filesystem to Garage:
```bash
mc mirror --newer-than "3h" ./public/system/ garage/mastodon-data
```

sftpgo initprovider
```
Then you can directly launch the daemon that will listen by default on `:8080 (http)` and `:2022 (ssh)`:
```
sftpgo serve
```
Go to the admin web interface (http://[::1]:8080/web/admin/), create the required admin account, then create a user account.
Choose a username (eg: `ada`) and a password.
In the filesystem section, choose:
- Storage: AWS S3 (Compatible)
- Bucket: *your bucket name*
- Region: `garage` (or the one you defined in `config.toml`)
- Access key: *your access key*
- Access secret: *your secret key*
- Endpoint: *your endpoint*, eg. `https://garage.example.tld`, note that the protocol (`https` here) must be specified. Non standard ports and `http` have not been tested yet.
- Keep the default values for other fields
- Tick "Use path-style addressing". It should work without ticking it if you have correctly configured your instance to use URL vhost-style.
Now you can access your bucket through SFTP:
```
sftp -P2022 ada@[::1]
ls
```

# Exposing buckets as websites
You can expose your bucket as a website with this simple command:
```bash
garage bucket website --allow my-website
```
Now it will be **publicly** exposed on the web endpoint (by default listening on port 3902).
Our website serving logic is as follow:
- Supports only static websites (no support for PHP or other languages)
- Does not support directory listing
- The index is defined in your `garage.toml`. ([ref](/reference_manual/configuration.html#index))
Now we need to infer the URL of your website through your bucket name.
Let assume:
- we set `root_domain = ".web.example.com"` in `garage.toml` ([ref](/reference_manual/configuration.html#root_domain))
- our bucket name is `garagehq.deuxfleurs.fr`.
Our bucket will be served if the Host field matches one of these 2 values (the port is ignored):
- `garagehq.deuxfleurs.fr.web.example.com`: you can dedicate a subdomain to your users (here `web.example.com`).
- `garagehq.deuxfleurs.fr`: your users can bring their own domain name, they just need to point them to your Garage cluster.
You can try this logic locally, without configuring any DNS, thanks to `curl`:
```bash
# prepare your test
echo hello world > /tmp/index.html
mc cp /tmp/index.html garage/garagehq.deuxfleurs.fr
curl -H 'Host: garagehq.deuxfleurs.fr' http://localhost:3902
# should print "hello world"
curl -H 'Host: garagehq.deuxfleurs.fr.web.example.com' http://localhost:3902
# should also print "hello world"
```
Now that you understand how website logic works on Garage, you can:
- make the website endpoint listens on port 80 (instead of 3902)
- use iptables to redirect the port 80 to the port 3902:
`iptables -t nat -A PREROUTING -p tcp -dport 80 -j REDIRECT -to-port 3902`
- or configure a [reverse proxy](reverse_proxy.html) in front of Garage to add TLS (HTTPS), CORS support, etc.
You can also take a look at [Website Integration](/connect/websites.html) to see how you can add Garage to your workflow.

# Compiling Garage from source
Garage is a standard Rust project.
First, you need `rust` and `cargo`.
For instance on Debian:
```bash
sudo apt-get update
sudo apt-get install -y rustc cargo
```
You can also use [Rustup](https://rustup.rs/) to setup a Rust toolchain easily.
## Using source from `crates.io`
Garage's source code is published on `crates.io`, Rust's official package repository.
This means you can simply ask `cargo` to download and build this source code for you:
```bash
cargo install garage
```
That's all, `garage` should be in `$HOME/.cargo/bin`.
You can add this folder to your `$PATH` or copy the binary somewhere else on your system.
For instance:
```bash
sudo cp $HOME/.cargo/bin/garage /usr/local/bin/garage
```
## Using source from the Gitea repository
The primary location for Garage's source code is the
[Gitea repository](https://git.deuxfleurs.fr/Deuxfleurs/garage).
Clone the repository and build Garage with the following commands:
```bash
git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
cd garage
cargo build
```
Be careful, as this will make a debug build of Garage, which will be extremely slow!
To make a release build, invoke `cargo build --release` (this takes much longer).
The binaries built this way are found in `target/{debug,release}/garage`.

Note that Garage will **always** store the three copies of your data on nodes at different
locations. This means that in the case of this small example, the available capacity
of the cluster is in fact only 1.5 TB, because nodes in Brussels can't store more than that.
This also means that nodes in Paris and London will be under-utilized.
To make better use of the available hardware, you should ensure that the capacity
available in the different locations of your cluster is roughly the same.
For instance, here, the Mercury node could be moved to Brussels; this would allow the cluster
to store 2 TB of data in total.
### Best practices
- If you have fast dedicated networking between all your nodes, and are planing to store
very large files, bump the `block_size` configuration parameter to 10 MB
(`block_size = 10485760`).
- Garage stores its files in two locations: it uses a metadata directory to store frequently-accessed
small metadata items, and a data directory to store data blocks of uploaded objects.
Ideally, the metadata directory would be stored on an SSD (smaller but faster),
and the data directory would be stored on an HDD (larger but slower).
- For the data directory, Garage already does checksumming and integrity verification,
so there is no need to use a filesystem such as BTRFS or ZFS that does it.
We recommend using XFS for the data partition, as it has the best performance.
EXT4 is not recommended as it has more strict limitations on the number of inodes,
which might cause issues with Garage when large numbers of objects are stored.
- If you only have an HDD and no SSD, it's fine to put your metadata alongside the data
on the same drive. Having lots of RAM for your kernel to cache the metadata will
help a lot with performance. Make sure to use the LMDB database engine,
instead of Sled, which suffers from quite bad performance degradation on HDDs.
Sled is still the default for legacy reasons, but is not recommended anymore.
- For the metadata storage, Garage does not do checksumming and integrity
verification on its own. If you are afraid of bitrot/data corruption,
put your metadata directory on a BTRFS partition. Otherwise, just use regular
EXT4 or XFS.
- Having a single server with several storage drives is currently not very well
supported in Garage ([#218](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/218)).
For an easy setup, just put all your drives in a RAID0 or a ZFS RAIDZ array.
If you're adventurous, you can try to format each of your disk as
a separate XFS partition, and then run one `garage` daemon per disk drive,
or use something like [`mergerfs`](https://github.com/trapexit/mergerfs) to merge
all your disks in a single union filesystem that spreads load over them.

# Configuring a reverse proxy
The main reason to add a reverse proxy in front of Garage is to provide TLS to your users and serve multiple web services on port 443.
In production you will likely need your certificates signed by a certificate authority.
The most automated way is to use a provider supporting the [ACME protocol](https://datatracker.ietf.org/doc/html/rfc8555)
such as [Let's Encrypt](https://letsencrypt.org/), [ZeroSSL](https://zerossl.com/) or [Buypass Go SSL](https://www.buypass.com/ssl/products/acme).
If you are only testing Garage, you can generate a self-signed certificate to follow the documentation:
```bash
openssl req \
-new \
-x509 \
-keyout /tmp/garage.key \
-out /tmp/garage.crt \
-nodes \
-subj "/C=XX/ST=XX/L=XX/O=XX/OU=XX/CN=localhost/emailAddress=X@X.XX" \
-addext "subjectAltName = DNS:localhost, IP:127.0.0.1"
cat /tmp/garage.key /tmp/garage.crt > /tmp/garage.pem
```
Be careful as you will need to allow self signed certificates in your client.
For example, with minio, you must add the `--insecure` flag.
An example:
```bash
mc ls --insecure garage/
```
## socat (only for testing purposes)
If you want to test Garage with a TLS frontend, socat can do it for you in a single command:
```bash
socat \
"openssl-listen:443,\
reuseaddr,\
fork,\
verify=0,\
cert=/tmp/garage.pem" \
tcp4-connect:localhost:3900
```
## Nginx
Nginx is a well-known reverse proxy suitable for production.
We do the configuration in 3 steps: first we define the upstream blocks ("the backends")
then we define the server blocks ("the frontends") for the S3 endpoint and finally for the web endpoint.
The following configuration blocks can be all put in the same `/etc/nginx/sites-available/garage.conf`.
To make your configuration active, run `ln -s /etc/nginx/sites-available/garage.conf /etc/nginx/sites-enabled/`.
If you directly put the instructions in the root `nginx.conf`, keep in mind that these configurations must be enclosed inside a `http { }` block.
And do not forget to reload nginx with `systemctl reload nginx` or `nginx -s reload`.
### Exposing the S3 endpoints
First, we need to tell to nginx how to access our Garage cluster.
Because we have multiple nodes, we want to leverage all of them by spreading the load.
In nginx, we can do that with the `upstream` directive.
Then in a `server` directive, we define the vhosts, the TLS certificates and the proxy rule.
A possible configuration:
```nginx
upstream s3_backend {
# if you have a garage instance locally
server 127.0.0.1:3900;
# you can also put your other instances
server 192.168.1.3:3900;
# domain names also work
server garage1.example.com:3900;
# you can assign weights if you have some servers
# that are more powerful than others
server garage2.example.com:3900 weight=2;
}
server {
listen [::]:443 http2 ssl;
ssl_certificate /tmp/garage.crt;
ssl_certificate_key /tmp/garage.key;
# You need multiple server names here:
# - s3.garage.tld is used for path-based s3 requests
# - *.s3.garage.tld is used for vhost-based s3 requests
server_name s3.garage.tld *.s3.garage.tld;
location / {
proxy_pass http://s3_backend;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
}
}
```
## Exposing the web endpoint
To better understand the logic involved, you can refer to the [Exposing buckets as websites](/cookbook/exposing_websites.html) section.
Otherwise, the configuration is very similar to the S3 endpoint.
You must only adapt `upstream` with the web port instead of the s3 port and change the `server_name` and `proxy_pass` entry
A possible configuration:
```nginx
upstream web_backend {
server 127.0.0.1:3902;
server 192.168.1.3:3902;
server garage1.example.com:3902;
server garage2.example.com:3902 weight=2;
}
server {
listen [::]:443 http2 ssl;
ssl_certificate /tmp/garage.crt;
ssl_certificate_key /tmp/garage.key;
# You need multiple server names here:
# - *.web.garage.tld is used for your users wanting a website without reserving a domain name
# - example.com, my-site.tld, etc. are reserved domain name by your users that chose to host their website as a garage's bucket
server_name *.web.garage.tld example.com my-site.tld;
location / {
proxy_pass http://web_backend;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
}
}

## Request routing logic
Data retrieval requests to Garage endpoints (S3 API and websites) are resolved
to an individual object in a bucket. Since objects are replicated to multiple nodes
Garage must ensure consistency before answering the request.
### Using quorum to ensure consistency
Garage ensures consistency by attempting to establish a quorum with the
data nodes responsible for the object. When a majority of the data nodes
have provided metadata on a object Garage can then answer the request.
When a request arrives Garage will, assuming the recommended 3 replicas, perform the following actions:
- Make a request to the two preferred nodes for object metadata
- Try the third node if one of the two initial requests fail
- Check that the metadata from at least 2 nodes match
- Check that the object hasn't been marked deleted
- Answer the request with inline data from metadata if object is small enough
- Or get data blocks from the preferred nodes and answer using the assembled object
Garage dynamically determines which nodes to query based on health, preference, and
which nodes actually host a given data. Garage has no concept of "primary" so any
healthy node with the data can be used as long as a quorum is reached for the metadata.
### Node health
Garage keeps a TCP session open to each node in the cluster and periodically pings them. If a connection
cannot be established, or a node fails to answer a number of pings, the target node is marked as failed.
Failed nodes are not used for quorum or other internal requests.
### Node preference
Garage prioritizes which nodes to query according to a few criteria:
- A node always prefers itself if it can answer the request
- Then the node prioritizes nodes in the same zone
- Finally the nodes with the lowest latency are prioritized
For further reading on the cluster structure look at the [gateway](@/documentation/cookbook/gateways.md)
and [cluster layout management](@/documentation/reference-manual/layout.md) pages.

# Data resiliency for everyone
Garage is an **open-source** distributed **storage service** you can **self-host** to fullfill many needs:
<p align="center" style="text-align:center; margin-bottom: 5rem;">
<img alt="Summary of the possible usages with a related icon: host a website, store media and backup target" src="img/usage.svg" />

</p>
Garage implements the **[Amazon S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html)** and thus is already **compatible** with many applications:
<p align="center" style="text-align:center; margin-bottom: 8rem;">
<img alt="Garage is already compatible with Nextcloud, Mastodon, Matrix Synapse, Cyberduck, RClone and Peertube" src="img/software.svg" />

Garage provides **data resiliency** by **replicating** data 3x over **distant** servers:

## Keeping requirements low
We worked hard to keep requirements as low as possible as we target the largest possible public.
* **CPU:** any x86\_64 CPU from the last 10 years, ARMv7 or ARMv8.
* **RAM:** 1GB
* **Disk Space:** at least 16GB
* **Network:** 200ms or less, 50 Mbps or more
* **Heterogeneous hardware:** build a cluster with whatever second-hand machines are available
*For the network, as we do not use consensus algorithms like Paxos or Raft, Garage is not as latency sensitive.*
*Thanks to Rust and its zero-cost abstractions, we keep CPU and memory low.*

Let's start your Garage journey!
In this chapter, we explain how to deploy Garage as a single-node server
and how to interact with it.
## What is Garage?
Before jumping in, you might be interested in reading the following pages:

## Configuring and starting Garage
### Generating a first configuration file
## Writing a first configuration file
This first configuration file should allow you to get started easily with the simplest
possible Garage deployment.
**Save it as `/etc/garage.toml`.**
You can also store it somewhere else, but you will have to specify `-c path/to/garage.toml`
at each invocation of the `garage` binary (for example: `garage -c ./garage.toml server`, `garage -c ./garage.toml status`).
We will create it with the following command line
to generate unique and private secrets for security reasons:
```bash
cat > garage.toml <<EOF
```toml
metadata_dir = "/tmp/meta"
data_dir = "/tmp/data"
db_engine = "lmdb"
replication_mode = "none"
rpc_bind_addr = "[::]:3901"
rpc_public_addr = "127.0.0.1:3901"
rpc_secret = "$(openssl rand -hex 32)"
rpc_secret = "1799bccfd7411eddcf9ebd316bc1f5287ad12a68094e1c6ac6abde7e6feae1ec"

@ -71,26 +55,12 @@ root_domain = ".s3.garage.localhost"
bind_addr = "[::]:3902"

api_bind_addr = "[::]:3904"
[admin]
api_bind_addr = "0.0.0.0:3903"
admin_token = "$(openssl rand -base64 32)"
EOF
```
Now that your configuration file has been created, you can put
it in the right place. By default, garage looks at **`/etc/garage.toml`.**
The `rpc_secret` value provided above is just an example. It will work, but in
order to secure your cluster you will need to use another one. You can generate
such a value with `openssl rand -hex 32`.
You can also store it somewhere else, but you will have to specify `-c path/to/garage.toml`
at each invocation of the `garage` binary (for example: `garage -c ./garage.toml server`, `garage -c ./garage.toml status`).
As you can see, the `rpc_secret` is a 32 bytes hexadecimal string.
You can regenerate it with `openssl rand -hex 32`.
If you target a cluster deployment with multiple nodes, make sure that
you use the same value for all nodes.
As you can see in the `metadata_dir` and `data_dir` parameters, we are saving Garage's data
in `/tmp` which gets erased when your system reboots. This means that data stored on this

## Uploading and downlading from Garage
To download and upload files on garage, we can use a third-party tool named `awscli`.
We recommend the use of MinIO Client to interact with Garage files (`mc`).
Instructions to install it and use it are provided on the
[MinIO website](https://docs.min.io/docs/minio-client-quickstart-guide.html).
Before reading the following, you need a working `mc` command on your path.
Note that on certain Linux distributions such as Arch Linux, the Minio client binary
is called `mcli` instead of `mc` (to avoid name clashes with the Midnight Commander).
### Install and configure `awscli`
#### Configure `mc`
If you have python on your system, you can install it with:
You need your access key and secret key created above.
We will assume you are invoking `mc` on the same machine as the Garage server,
your S3 API endpoint is therefore `http://127.0.0.1:3900`.
For this whole configuration, you must set an alias name: we chose `my-garage`, that you will used for all commands.
Adapt the following command accordingly and run it:
```bash
python -m pip install --user awscli
mc alias set \
my-garage \
http://127.0.0.1:3900 \
<access key> \
<secret key> \
--api S3v4
```
Now that `awscli` is installed, you must configure it to talk to your Garage instance,
with your key. There are multiple ways to do that, the simplest one is to create a file
named `~/.awsrc` with this content:
You must also add an environment variable to your configuration to
inform MinIO of our region (`garage` by default, corresponding to the `s3_region` parameter
in the configuration file).
The best way is to add the following snippet to your `$HOME/.bash_profile`
or `$HOME/.bashrc` file:
```bash
export AWS_ACCESS_KEY_ID=xxxx # put your Key ID here
export AWS_SECRET_ACCESS_KEY=xxxx # put your Secret key here
export AWS_DEFAULT_REGION='garage'
export AWS_ENDPOINT='http://localhost:3900'
function aws { command aws --endpoint-url $AWS_ENDPOINT $@ ; }
aws --version
export MC_REGION=garage
```
Now, each time you want to use `awscli` on this target, run:
#### Use `mc`
You can not list buckets from `mc` currently.
But the following commands and many more should work:
```bash
source ~/.awsrc
mc cp image.png my-garage/nextcloud-bucket
mc cp my-garage/nextcloud-bucket/image.png .
mc ls my-garage/nextcloud-bucket
mc mirror localdir/ my-garage/another-bucket
```
*You can create multiple files with different names if you
have multiple Garage clusters or different keys.
Switching from one cluster to another is as simple as
sourcing the right file.*
### Example usage of `awscli`
```bash
# list buckets
aws s3 ls
# list objects of a bucket
aws s3 ls s3://my_files
# copy from your filesystem to garage
aws s3 cp /proc/cpuinfo s3://my_files/cpuinfo.txt
# copy from garage to your filesystem
aws s3 cp s3/my_files/cpuinfo.txt /tmp/cpuinfo.txt
```
Note that you can use `awscli` for more advanced operations like
creating a bucket, pre-signing a request or managing your website.
[Read the full documentation to know more](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/s3/index.html).
Some features are however not implemented like ACL or policy.

[s3_web]
bind_addr = "[::]:3902"
root_domain = ".web.garage"
index = "index.html"
```
The following gives details about each available configuration option.
## Available configuration options
#### `metadata_dir`
The directory in which Garage will store its metadata. This contains the node identifier,
the network configuration and the peer list, the list of buckets and keys as well
as the index of all objects, object version and object blocks.
Store this folder on a fast SSD drive if possible to maximize Garage's performance.
#### `data_dir`
The directory in which Garage will store the data blocks of objects.
This folder can be placed on an HDD. The space available for `data_dir`
should be counted to determine a node's capacity
when [configuring it](../getting_started/05_cluster.md).
#### `block_size`
Garage splits stored objects in consecutive chunks of size `block_size`
(except the last one which might be smaller). The default size is 1MB and
should work in most cases. If you are interested in tuning this, feel free
to do so (and remember to report your findings to us!). If this value is
changed for a running Garage installation, only files newly uploaded will be
affected. Previously uploaded files will remain available. This however
means that chunks from existing files will not be deduplicated with chunks
from newly uploaded files, meaning you might use more storage space that is
optimally possible.
#### `replication_mode`
Garage supports the following replication modes:
- `none` or `1`: data stored on Garage is stored on a single node. There is no redundancy,
and data will be unavailable as soon as one node fails or its network is disconnected.
Do not use this for anything else than test deployments.
- `2`: data stored on Garage will be stored on two different nodes, if possible in different
zones. Garage tolerates one node failure before losing data. Data should be available
read-only when one node is down, but write operations will fail.
Use this only if you really have to.
- `3`: data stored on Garage will be stored on three different nodes, if possible each in
a different zones.
Garage tolerates two node failure before losing data. Data should be available
read-only when two nodes are down, and writes should be possible if only a single node
is down.
Note that in modes `2` and `3`,
if at least the same number of zones are available, an arbitrary number of failures in
any given zone is tolerated as copies of data will be spread over several zones.
**Make sure `replication_mode` is the same in the configuration files of all nodes.
Never run a Garage cluster where that is not the case.**
Changing the `replication_mode` of a cluster might work (make sure to shut down all nodes
and changing it everywhere at the time), but is not officially supported.
### `compression_level`
Zstd compression level to use for storing blocks.
Values between `1` (faster compression) and `19` (smaller file) are standard compression
levels for zstd. From `20` to `22`, compression levels are referred as "ultra" and must be
used with extra care as it will use lot of memory. A value of `0` will let zstd choose a
default value (currently `3`). Finally, zstd has also compression designed to be faster
than default compression levels, they range from `-1` (smaller file) to `-99` (faster
compression).
If you do not specify a `compression_level` entry, garage will set it to `1` for you. With
this parameters, zstd consumes low amount of cpu and should work faster than line speed in
most situations, while saving some space and intra-cluster
bandwidth.
If you want to totally deactivate zstd in garage, you can pass the special value `'none'`. No
zstd related code will be called, your chunks will be stored on disk without any processing.
Compression is done synchronously, setting a value too high will add latency to write queries.
This value can be different between nodes, compression is done by the node which receive the
API call.
#### `rpc_secret`
Garage uses a secret key that is shared between all nodes of the cluster
in order to identify these nodes and allow them to communicate together.
This key should be specified here in the form of a 32-byte hex-encoded
random string. Such a string can be generated with a command
such as `openssl rand -hex 32`.
#### `rpc_bind_addr`
The address and port on which to bind for inter-cluster communcations
(reffered to as RPC for remote procedure calls).
The port specified here should be the same one that other nodes will used to contact
the node, even in the case of a NAT: the NAT should be configured to forward the external
port number to the same internal port nubmer. This means that if you have several nodes running
behind a NAT, they should each use a different RPC port number.
#### `rpc_public_addr`
The address and port that other nodes need to use to contact this node for
RPC calls. **This parameter is optional but recommended.** In case you have
a NAT that binds the RPC port to a port that is different on your public IP,
this field might help making it work.
#### `bootstrap_peers`
A list of peer identifiers on which to contact other Garage peers of this cluster.
These peer identifiers have the following syntax:
```
<node public key>@<node public IP or hostname>:<port>
```
In the case where `rpc_public_addr` is correctly specified in the
configuration file, the full identifier of a node including IP and port can
be obtained by running `garage node id` and then included directly in the
`bootstrap_peers` list of other nodes. Otherwise, only the node's public
key will be returned by `garage node id` and you will have to add the IP
yourself.
#### `consul_host` and `consul_service_name`
Garage supports discovering other nodes of the cluster using Consul.
This works only when nodes are announced in Consul by an orchestrator such as Nomad,
as Garage is not able to announce itself.
The `consul_host` parameter should be set to the hostname of the Consul server,
and `consul_service_name` should be set to the service name under which Garage's
RPC ports are announced.
#### `sled_cache_capacity`
This parameter can be used to tune the capacity of the cache used by
[sled](https://sled.rs), the database Garage uses internally to store metadata.
Tune this to fit the RAM you wish to make available to your Garage instance.
More cache means faster Garage, but the default value (128MB) should be plenty
for most use cases.
#### `sled_flush_every_ms`
This parameters can be used to tune the flushing interval of sled.
Increase this if sled is thrashing your SSD, at the risk of losing more data in case
of a power outage (though this should not matter much as data is replicated on other
nodes). The default value, 2000ms, should be appropriate for most use cases.
## The `[s3_api]` section
#### `api_bind_addr`
The IP and port on which to bind for accepting S3 API calls.
This endpoint does not suport TLS: a reverse proxy should be used to provide it.
#### `s3_region`
Garage will accept S3 API calls that are targetted to the S3 region defined here.
API calls targetted to other regions will fail with a AuthorizationHeaderMalformed error
message that redirects the client to the correct region.
#### `root_domain`
The optionnal suffix to access bucket using vhost-style in addition to path-style request.
Note path-style requests are always enabled, whether or not vhost-style is configured.
Configuring vhost-style S3 required a wildcard DNS entry, and possibly a wildcard TLS certificate,
but might be required by softwares not supporting path-style requests.
If `root_domain` is `s3.garage.eu`, a bucket called `my-bucket` can be interacted with
using the hostname `my-bucket.s3.garage.eu`.
## The `[s3_web]` section
Garage allows to publish content of buckets as websites. This section configures the
behaviour of this module.
#### `bind_addr`
The IP and port on which to bind for accepting HTTP requests to buckets configured
for website access.
This endpoint does not suport TLS: a reverse proxy should be used to provide it.
#### `root_domain`
The optionnal suffix appended to bucket names for the corresponding HTTP Host.
For instance, if `root_domain` is `web.garage.eu`, a bucket called `deuxfleurs.fr`
will be accessible either with hostname `deuxfleurs.fr.web.garage.eu`
or with hostname `deuxfleurs.fr`.
#### `index`
The name of the index file to return for requests ending with `/` (usually `index.html`).

# Creating and updating a cluster layout
The cluster layout in Garage is a table that assigns to each node a role in
the cluster. The role of a node in Garage can either be a storage node with
a certain capacity, or a gateway node that does not store data and is only
used as an API entry point for faster cluster access.

3. Check once again that your cluster is healty. Run again `garage repair --all-nodes --yes tables` which is quick.
Also check your queues are empty, run `garage stats` to query them.
4. Turn off Garage v0.6
5. Backup the metadata folder of all your nodes: `cd /var/lib/garage ; tar -acf meta-v0.6.tar.zst meta/`
6. Install Garage v0.7, edit the configuration if you plan to use OpenTelemetry or the Kubernetes integration
7. Turn on Garage v0.7
8. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`
9. Your upgraded cluster should be in a working state. Re-enable API and Web
access and check that everything went well.
10. Monitor your cluster in the next hours to see if it works well under your production load, report any issue.

**This guide explains how to migrate to 0.8 if you have an existing 0.7 cluster.
We don't recommend trying to migrate to 0.8 directly from 0.6 or older.**
**We make no guarantee that this migration will work perfectly:
back up all your data before attempting it!**
Garage v0.8 introduces new data tables that allow the counting of objects in buckets in order to implement bucket quotas.
A manual migration step is required to first count objects in Garage buckets and populate these tables with accurate data.
The migration steps are as follows:
1. Disable API and web access. Garage v0.7 does not support disabling
these endpoints but you can change the port number or stop your reverse proxy for instance.
2. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`,
check the logs and check that all data seems to be synced correctly between
nodes. If you have time, do additional checks (`scrub`, `block_refs`, etc.)
3. Check that queues are empty: run `garage stats` to query them or inspect metrics in the Grafana dashboard.
4. Turn off Garage v0.7
5. **Backup the metadata folder of all your nodes!** For instance, use the following command
if your metadata directory is `/var/lib/garage/meta`: `cd /var/lib/garage ; tar -acf meta-v0.7.tar.zst meta/`
6. Install Garage v0.8
7. **Before starting Garage v0.8**, run the offline migration step: `garage offline-repair --yes object_counters`.
This can take a while to run, depending on the number of objects stored in your cluster.
8. Turn on Garage v0.8
9. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`.
Wait for a full table sync to run.
10. Your upgraded cluster should be in a working state. Re-enable API and Web
access and check that everything went well.
11. Monitor your cluster in the next hours to see if it works well under your production load, report any issue.

## Testing Garage
Currently, we have the following tests:
- some unit tests spread around the codebase
- integration tests written in Rust (`src/garage/test`) to check that Garage operations perform correctly
- integration test for compatibility with external tools (`script/test-smoke.sh`)
We have also tried `minio/mint` but it fails a lot and for now we haven't gotten a lot from it.
In the future:
1. We'd like to have a systematic way of testing with `minio/mint`,
it would add value to Garage by providing a compatibility score and reference that can be trusted.
2. We'd also like to do testing with Jepsen in some way.
## How to instrument Garagae
We should try to test in least invasive ways, i.e. minimize the impact of the testing framework on Garage's source code. This means for example:
- Not abstracting IO/nondeterminism in the source code
- Not making `garage` a shared library (launch using `execve`, it's perfectly fine)
Instead, we should focus on building a clean outer interface for the `garage` binary,
for example loading configuration using environnement variables instead of the configuration file if that's helpfull for writing the tests.
There are two reasons for this:
- Keep the soure code clean and focused
- Test something that is as close as possible as the true garage that will actually be running
Reminder: rules of simplicity, concerning changes to Garage's source code.
Always question what we are doing.
Never do anything just because it looks nice or because we "think" it might be usefull at some later point but without knowing precisely why/when.
Only do things that make perfect sense in the context of what we currently know.

Testing is a research field on its own.
About testing distributed systems:
- [Jepsen](https://jepsen.io/) is a testing framework designed to test distributed systems. It can mock some part of the system like the time and the network.
- [FoundationDB Testing Approach](https://www.micahlerner.com/2021/06/12/foundationdb-a-distributed-unbundled-transactional-key-value-store.html#what-is-unique-about-foundationdbs-testing-framework). They chose to abstract "all sources of nondeterminism and communication are abstracted, including network, disk, time, and pseudo random number generator" to be able to run tests by simulating faults.

Misc:
- [mutagen](https://github.com/llogiq/mutagen) - mutation testing is a way to assert our test quality by mutating the code and see if the mutation makes the tests fail
- [fuzzing](https://rust-fuzz.github.io/book/) - cargo supports fuzzing, it could be a way to test our software reliability in presence of garbage data.
