af261e1789 Fix a bug when a migration is followed by a rebalance
Nodes would stabilize on different encoding formats for the values,
some having the pre-migration format and some having the post-migration
format. This would be reflected in the Merkle trees never converging
and thus having an infinite resync loop.

b4592a00fe Implement ListMultipartUploads (#171)
Implement ListMultipartUploads, also refactor ListObjects and ListObjectsV2.

It took me some times as I wanted to propose the following things:
  - Using an iterator instead of the loop+goto pattern. I find it easier to read and it should enable some optimizations. For example, when consuming keys of a common prefix, we do many [redundant checks](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/main/src/api/s3_list.rs#L125-L156) while the only thing to do is to [check if the following key is still part of the common prefix](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/feature/s3-multipart-compat/src/api/s3_list.rs#L476).
  - Try to name things (see ExtractionResult and RangeBegin enums) and to separate concerns (see ListQuery and Accumulator)
  - An IO closure to make unit tests possibles.
  - Unit tests, to track regressions and document how to interact with the code
  - Integration tests with `s3api`. In the future, I would like to move them in Rust with the aws rust SDK.

Merging of the logic of ListMultipartUploads and ListObjects was not a goal but a consequence of the previous modifications.

Some points that we might want to discuss:
  - ListObjectsV1, when using pagination and delimiters, has a weird behavior (it lists multiple times the same prefix) with `aws s3api` due to the fact that it can not use our optimization to skip the whole prefix. It is independant from my refactor and can be tested with the commented `s3api` tests in `test-smoke.sh`. It probably has the same weird behavior on the official AWS S3 implementation.
  - Considering ListMultipartUploads, I had to "abuse" upload id marker to support prefix skipping. I send an `upload-id-marker` with the hardcoded value `include` to emulate your "including" token.
  - Some ways to test ListMultipartUploads with existing software (my tests are limited to s3api for now).

New buckets for 0.6.0: small changes
- Fix bucket delete

- fix merge of bucket creation date

- Replace deletable with option in aliases
    Rationale: if two aliases point to conflicting bucket, resolving
    by making an arbitrary choice risks making data accessible when it
    shouldn't be. We'd rather resolve to deleting the alias until
    someone puts it back.

c4ac8835d3 add proper request router for s3 api (#163)
fix #161

Current request router was organically grown, and is getting messier and messier with each addition.
This router cover exaustively existing API endpoints (with exceptions listed in [#161(comment)](Deuxfleurs/garage#161 (comment)) either because new and old api endpoint can't feasabily be differentied, or it's more lambda than s3).

Improve how node roles are assigned in Garage
- change the terminology: the network configuration becomes the role
  table, the configuration of a nodes becomes a node's role
- the modification of the role table takes place in two steps: first,
  changes are staged in a CRDT data structure. Then, once the user is
  happy with the changes, they can commit them all at once (or revert
  them).
- update documentation
- fix tests
- implement smarter partition assignation algorithm

This patch breaks the format of the network configuration: when
migrating, the cluster will be in a state where no roles are assigned.
All roles must be re-assigned and commited at once. This migration
should not pose an issue.

Testing
-------
How are we going to test that our replication method works correctly?
We will have to introduce lots of dummy data and then add/remove nodes many times.
Attaining S3 compatibility
--------------------------
- test multipart uploads
- get ranges
- fix sync not working in some cases ? (when starting from empty?)
- api_server following the S3 semantics for head/get/put/list/delete: verify more that it works as intended
- PUT requests: verify content-md5 if provided
- possibly other necessary endpoints ?
Lower priority
--------------
- less a priority: hinted handoff
- repair: re-propagate block ref table to rc
- FIXME in rpc_server when garage shuts down and futures can be interrupted
(tokio::spawn should be replaced by a new function background::spawn_joinable)

Instead, we build our own rustChannel object with the recommended API of rust-overlay. rustc was built with musl < 1.2.0 and nix shipped musl >= 1.2.0 which lead to compilation breakage.

## Nextcloud
Nextcloud is a popular file synchronisation and backup service.
By default, Nextcloud stores its data on the local filesystem.
If you want to expand your storage to aggregate multiple servers, Garage is the way to go.
A S3 backend can be configured in two ways on Nextcloud, either as Primary Storage or as an External Storage.
Primary storage will store all your data on S3, in an opaque manner, and will provide the best performances.
External storage enable you to select which data will be stored on S3, your file hierarchy will be preserved in S3, but it might be slower.
In the following, we cover both methods but before reading our guide, we suppose you have done some preliminary steps.
First, we expect you have an already installed and configured Nextcloud instance.
Second, we suppose you have created a key and a bucket.
As a reminder, you can create a key for your nextcloud instance as follow:
```bash
garage key new --name nextcloud-key
```
Keep the Key ID and the Secret key in a pad, they will be needed later.
Then you can create a bucket and give read/write rights to your key on this bucket with:
```bash
garage bucket create nextcloud
garage bucket allow nextcloud --read --write --key nextcloud-key
```
### Primary Storage
Now edit your Nextcloud configuration file to enable object storage.
On my installation, the config. file is located at the following path: `/var/www/nextcloud/config/config.php`.
We will add a new root key to the `$CONFIG` dictionnary named `objectstore`:
```php
<?php
$CONFIG = array(
/* your existing configuration */
'objectstore' => [
'class' => '\\OC\\Files\\ObjectStore\\S3',
'arguments' => [
'bucket' => 'nextcloud', // Your bucket name, must be created before
'autocreate' => false, // Garage does not support autocreate
'key' => 'xxxxxxxxx', // The Key ID generated previously
'secret' => 'xxxxxxxxx', // The Secret key generated previously
'hostname' => '127.0.0.1', // Can also be a domain name, eg. garage.example.com
'port' => 3900, // Put your reverse proxy port or your S3 API port
'use_ssl' => false, // Set it to true if you have a TLS enabled reverse proxy
'region' => 'garage', // Garage has only one region named "garage"
'use_path_style' => true // Garage supports only path style, must be set to true
],
],
```
That's all, your Nextcloud will store all your data to S3.
To test your new configuration, just reload your Nextcloud webpage and start sending data.
*External link:* [Nextcloud Documentation > Primary Storage](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/primary_storage.html)
### External Storage
**From the GUI.** Activate the "External storage support" app from the "Applications" page (click on your account icon on the top right corner of your screen to display the menu). Go to your parameters page (also located below your account icon). Click on external storage (or the corresponding translation in your language).
[![Screenshot of the External Storage form](cli-nextcloud-gui.png)](cli-nextcloud-gui.png)
*Click on the picture to zoom*
Add a new external storage. Put what you want in "folder name" (eg. "shared"). Select "Amazon S3". Keep "Access Key" for the Authentication field.
In Configuration, put your bucket name (eg. nextcloud), the host (eg. 127.0.0.1), the port (eg. 3900 or 443), the region (garage). Tick the SSL box if you have put an HTTPS proxy in front of garage. You must tick the "Path access" box and you must leave the "Legacy authentication (v2)" box empty. Put your Key ID (eg. GK...) and your Secret Key in the last two input boxes. Finally click on the tick symbol on the right of your screen.
Now go to your "Files" app and a new "linked folder" has appeared with the name you chose earlier (eg. "shared").
*External link:* [Nextcloud Documentation > External Storage Configuration GUI](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage_configuration_gui.html)
**From the CLI.** First install the external storage application:
```bash
php occ app:install files_external
```
Then add a new mount point with:
```bash
php occ files_external:create \
-c bucket=nextcloud \
-c hostname=127.0.0.1 \
-c port=3900 \
-c region=garage \
-c use_ssl=false \
-c use_path_style=true \
-c legacy_auth=false \
-c key=GKxxxx \
-c secret=xxxx \
shared amazons3 amazons3::accesskey
```
Adapt the `hostname`, `port`, `use_ssl`, `key`, and `secret` entries to your configuration.
Do not change the `use_path_style` and `legacy_auth` entries, other configurations are not supported.
*External link:* [Nextcloud Documentation > occ command > files external](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/occ_command.html#files-external-label)
## Peertube
Peertube proposes a clever integration of S3 by directly exposing its endpoint instead of proxifying requests through the application.
In other words, Peertube is only responsible of the "control plane" and offload the "data plane" to Garage.
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.
### Create resources in Garage
Create a key for Peertube:
```bash
garage key new --name peertube-key
```
Keep the Key ID and the Secret key in a pad, they will be needed later.
We need two buckets, one for normal videos (named peertube-video) and one for webtorrent videos (named peertube-playlist).
```bash
garage bucket create peertube-video
garage bucket create peertube-playlist
```
Now we allow our key to read and write on these buckets:
```
garage bucket allow peertube-playlists --read --write --owner --key peertube-key
garage bucket allow peertube-videos --read --write --owner --key peertube-key
```
We also need to expose these buckets publicly to serve their content to users:
```bash
garage bucket website --allow peertube-playlists
garage bucket website --allow peertube-videos
```
Finally, we must allow Cross-Origin Resource Sharing (CORS).
CORS are required by your browser to allow requests triggered from the peertube website (eg. peertube.tld) to your bucket's domain (eg. peertube-videos.web.garage.tld)
```bash
export CORS='{"CORSRules":[{"AllowedHeaders":["*"],"AllowedMethods":["GET"],"AllowedOrigins":["*"]}]}'
aws --endpoint http://s3.garage.localhost s3api put-bucket-cors --bucket peertube-playlists --cors-configuration $CORS
aws --endpoint http://s3.garage.localhost s3api put-bucket-cors --bucket peertube-videos --cors-configuration $CORS
```
These buckets are now accessible on the web port (by default 3902) with the following URL: `http://<bucket><root_domain>:<web_port>` where the root domain is defined in your configuration file (by default `.web.garage`). So we have currently the following URLs:
* http://peertube-playlists.web.garage:3902
* http://peertube-videos.web.garage:3902
Make sure you (will) have a corresponding DNS entry for them.
### Configure Peertube
You must edit the file named `config/production.yaml`, we are only modifying the root key named `object_storage`:
```yaml
object_storage:
enabled: true
# Put localhost only if you have a garage instance running on that node
endpoint: 'http://localhost:3900' # or "garage.example.com" if you have TLS on port 443
# Garage supports only one region for now, named garage
region: 'garage'
credentials:
access_key_id: 'GKxxxx'
secret_access_key: 'xxxx'
max_upload_part: 2GB
streaming_playlists:
bucket_name: 'peertube-playlist'
# Keep it empty for our example
prefix: ''
# You must fill this field to make Peertube use our reverse proxy/website logic
base_url: 'http://peertube-playlists.web.garage.localhost' # Example: 'https://mirror.example.com'
# Same settings but for webtorrent videos
videos:
bucket_name: 'peertube-video'
prefix: ''
# You must fill this field to make Peertube use our reverse proxy/website logic
base_url: 'http://peertube-videos.web.garage.localhost'
```
### That's all
Everything must be configured now, simply restart Peertube and try to upload a video.
Peertube will start by serving the video from its own domain while it is encoding.
Once the encoding is done, the video is uploaded to Garage.
You can now reload the page and see in your browser console that data are fetched directly from your bucket.
*External link:* [Peertube Documentation > Remote Storage](https://docs.joinpeertube.org/admin-remote-storage)
## Mastodon
https://docs.joinmastodon.org/admin/config/#cdn
## Matrix
Matrix is a chat communication protocol. Its main stable server implementation, [Synapse](https://matrix-org.github.io/synapse/latest/), provides a module to store media on a S3 backend. Additionally, a server independent media store supporting S3 has been developped by the community, it has been made possible thanks to how the matrix API has been designed and will work with implementations like Conduit, Dendrite, etc.
### synapse-s3-storage-provider (synapse only)
Supposing you have a working synapse installation, you can add the module with pip:
```bash
pip3 install --user git+https://github.com/matrix-org/synapse-s3-storage-provider.git
```
Now create a bucket and a key for your matrix instance (note your Key ID and Secret Key somewhere, they will be needed later):
```bash
garage key new --name matrix-key
garage bucket create matrix
garage bucket allow matrix --read --write --key matrix-key
```
Then you must edit your server configuration (eg. `/etc/matrix-synapse/homeserver.yaml`) and add the `media_storage_providers` root key:
```yaml
media_storage_providers:
- module: s3_storage_provider.S3StorageProviderBackend
store_local: True # do we want to store on S3 media created by our users?
store_remote: True # do we want to store on S3 media created
# by users of others servers federated to ours?
store_synchronous: True # do we want to wait that the file has been written before returning?
config:
bucket: matrix # the name of our bucket, we chose matrix earlier
region_name: garage # only "garage" is supported for the region field
endpoint_url: http://localhost:3900 # the path to the S3 endpoint
access_key_id: "GKxxx" # your Key ID
secret_access_key: "xxxx" # your Secret Key
```
Note that uploaded media will also be stored locally and this behavior can not be deactivated, it is even required for
some operations like resizing images.
In fact, your local filesysem is considered as a cache but without any automated way to garbage collect it.
We can build our garbage collector with `s3_media_upload`, a tool provided with the module.
If you installed the module with the command provided before, you should be able to bring it in your path:
```
PATH=$HOME/.local/bin/:$PATH
command -v s3_media_upload
```
Now we can write a simple script (eg `~/.local/bin/matrix-cache-gc`):
```bash
#!/bin/bash
## CONFIGURATION ##
AWS_ACCESS_KEY_ID=GKxxx
AWS_SECRET_ACCESS_KEY=xxxx
S3_ENDPOINT=http://localhost:3900
S3_BUCKET=matrix
MEDIA_STORE=/var/lib/matrix-synapse/media
PG_USER=matrix
PG_PASS=xxxx
PG_DB=synapse
PG_HOST=localhost
PG_PORT=5432
## CODE ##
PATH=$HOME/.local/bin/:$PATH
cat > database.yaml <<EOF
user: $PG_USER
password: $PG_PASS
database: $PG_DB
host: $PG_HOST
port: $PG_PORT
EOF
s3_media_upload update-db 1d
s3_media_upload --no-progress check-deleted $MEDIA_STORE
s3_media_upload --no-progress upload $MEDIA_STORE $S3_BUCKET --delete --endpoint-url $S3_ENDPOINT
```
This script will list all the medias that were not accessed in the 24 hours according to your database.
It will check if, in this list, the file still exists in the local media store.
For files that are still in the cache, it will upload them to S3 if they are not already present (in case of a crash or an initial synchronisation).
Finally, the script will delete these files from the cache.
Make this script executable and check that it works:
```bash
chmod +x $HOME/.local/bin/matrix-cache-gc
matrix-cache-gc
```
Add it to your crontab. Open the editor with:
```bash
crontab -e
```
And add a new line. For example, to run it every 10 minutes:
```cron
*/10 * * * * $HOME/.local/bin/matrix-cache-gc
```

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`.

title = "Browsing tools"
weight = 20
+++
Browsing tools allow you to query the S3 API without too many abstractions.
These tools are particularly suitable for debug, backups, website deployments or any scripted task that need to handle data.
| Name | Status | Note |
|------|--------|------|
| [Minio client](#minio-client) | ✅ | Recommended |
| [AWS CLI](#aws-cli) | ✅ | Recommended |
| [rclone](#rclone) | ✅ | |
| [s3cmd](#s3cmd) | ✅ | |
| [(Cyber)duck](#cyberduck) | ✅ | |
| [WinSCP (libs3)](#winscp) | ✅ | No instructions yet |
## Minio client
Use the following command to set an "alias", i.e. define a new S3 server to be
used by the Minio client:
```bash
mc alias set \
garage \
<endpoint> \
<access key> \
<secret key> \
--api S3v4
```
Remember that `mc` is sometimes called `mcli` (such as on Arch Linux), to avoid conflicts
with Midnight Commander.
Some commands:
```bash
# list buckets
mc ls garage/
# list objets in a bucket
mc ls garage/my_files
# copy from your filesystem to garage
mc cp /proc/cpuinfo garage/my_files/cpuinfo.txt
# copy from garage to your filesystem
mc cp garage/my_files/cpuinfo.txt /tmp/cpuinfo.txt
# mirror a folder from your filesystem to garage
mc mirror --overwrite ./book garage/garagehq.deuxfleurs.fr
```
## AWS CLI
Create a file named `~/.aws/credentials` and put:
```toml
[default]
aws_access_key_id=xxxx
aws_secret_access_key=xxxx
```
Then a file named `~/.aws/config` and put:
```toml
[default]
region=garage
```
Now, supposing Garage is listening on `http://127.0.0.1:3900`, you can list your buckets with:
```bash
aws --endpoint-url http://127.0.0.1:3900 s3 ls
```
Passing the `--endpoint-url` parameter to each command is annoying but AWS developers do not provide a corresponding configuration entry.
As a workaround, you can redefine the aws command by editing the file `~/.bashrc`:
```
function aws { command aws --endpoint-url http://127.0.0.1:3900 $@ ; }
```
*Do not forget to run `source ~/.bashrc` or to start a new terminal before running the next commands.*
Now you can simply run:
```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
```
## `rclone`
`rclone` can be configured using the interactive assistant invoked using `rclone config`.
You can also configure `rclone` by writing directly its configuration file.
Here is a template `rclone.ini` configuration file (mine is located at `~/.config/rclone/rclone.conf`):
```ini
[garage]
type = s3
provider = Other
env_auth = false
access_key_id = <access key>
secret_access_key = <secret key>
region = <region>
endpoint = <endpoint>
force_path_style = true
acl = private
bucket_acl = private
```
Now you can run:
```bash
# list buckets
rclone lsd garage:
# list objects of a bucket aggregated in directories
rclone lsd garage:my-bucket
# copy from your filesystem to garage
echo hello world > /tmp/hello.txt
rclone copy /tmp/hello.txt garage:my-bucket/
# copy from garage to your filesystem
rclone copy garage:quentin.divers/hello.txt .
# see all available subcommands
rclone help
```
**Advice with rclone:** use the `--fast-list` option when accessing buckets with large amounts of objects.
This will tremendously accelerate operations such as `rclone sync` or `rclone ncdu` by reducing the number
of ListObjects calls that are made.
## `s3cmd`
Here is a template for the `s3cmd.cfg` file to talk with Garage:
```ini
[default]
access_key = <access key>
secret_key = <secret key>
host_base = <endpoint without http(s)://>
host_bucket = <same as host_base>
use_https = <False or True>
```
And use it as follow:
```bash
# List buckets
s3cmd ls
# s3cmd objects inside a bucket
s3cmd ls s3://my-bucket
# copy from your filesystem to garage
echo hello world > /tmp/hello.txt
s3cmd put /tmp/hello.txt s3://my-bucket/
# copy from garage to your filesystem
s3cmd get s3://my-bucket/hello.txt hello.txt
```
## Cyberduck & duck {#cyberduck}
Both Cyberduck (the GUI) and duck (the CLI) have a concept of "Connection Profiles" that contain some presets for a specific provider.
We wrote the following connection profile for Garage:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Protocol</key>
<string>s3</string>
<key>Vendor</key>
<string>garage</string>
<key>Scheme</key>
<string>https</string>
<key>Description</key>
<string>GarageS3</string>
<key>Default Hostname</key>
<string>127.0.0.1</string>
<key>Default Port</key>
<string>4443</string>
<key>Hostname Configurable</key>
<false/>
<key>Port Configurable</key>
<false/>
<key>Username Configurable</key>
<true/>
<key>Username Placeholder</key>
<string>Access Key ID (GK...)</string>
<key>Password Placeholder</key>
<string>Secret Key</string>
<key>Properties</key>
<array>
<string>s3service.disable-dns-buckets=true</string>
</array>
<key>Region</key>
<string>garage</string>
<key>Regions</key>
<array>
<string>garage</string>
</array>
</dict>
</plist>
```
*Note: If your garage instance is configured with vhost access style, you can remove `s3service.disable-dns-buckets=true`.*
### Instructions for the GUI
Copy the connection profile, and save it anywhere as `garage.cyberduckprofile`.
Then find this file with your file explorer and double click on it: Cyberduck will open a connection wizard for this profile.
Simply follow the wizard and you should be done!
### Instuctions for the CLI
To configure duck (Cyberduck's CLI tool), start by creating its folder hierarchy:
```
mkdir -p ~/.duck/profiles/
```
Then, save the connection profile for Garage in `~/.duck/profiles/garage.cyberduckprofile`.
To set your credentials in `~/.duck/credentials`, use the following commands to generate the appropriate string:
```bash
export AWS_ACCESS_KEY_ID="GK..."
export AWS_SECRET_ACCESS_KEY="..."
export HOST="s3.garage.localhost"
export PORT="4443"
export PROTOCOL="https"
cat > ~/.duck/credentials <<EOF
$PROTOCOL\://$AWS_ACCESS_KEY_ID@$HOST\:$PORT=$AWS_SECRET_ACCESS_KEY
EOF
```
And finally, I recommend appending a small wrapper to your `~/.bashrc` to avoid setting the username on each command (do not forget to replace `GK...` by your access key):
```bash
function duck { command duck --username GK... $@ ; }
```
Finally, you can then use `duck` as follow:
```bash
# List buckets
duck --list garage:/
# List objects in a bucket
duck --list garage:/my-files/
# Download an object
duck --download garage:/my-files/an-object.txt /tmp/object.txt
# Upload an object
duck --upload /tmp/object.txt garage:/my-files/another-object.txt
# Delete an object
duck --delete garage:/my-files/an-object.txt
```
## WinSCP (libs3) {#winscp}
*No instruction yet. You can find ones in french [in our wiki](https://wiki.deuxfleurs.fr/fr/Guide/Garage/WinSCP).*

If you are developping a new application, you may want to use Garage to store your user's media.
The S3 API that Garage uses is a standard REST API, so as long as you can make HTTP requests,
you can query it. You can check the [S3 REST API Reference](https://docs.aws.amazon.com/AmazonS3/latest/API/API_Operations_Amazon_Simple_Storage_Service.html) from Amazon to learn more.
Developping your own wrapper around the REST API is time consuming and complicated.
Instead, there are some libraries already avalaible.
Some of them are maintained by Amazon, some by Minio, others by the community.

**WARNING! Garage is not POSIX compatible.
Mounting S3 buckets as filesystems will not provide POSIX compatibility.
If you are not careful, you will lose or corrupt your data.**
Do not use these FUSE filesystems to store any database files (eg. MySQL, Postgresql, Mongo or sqlite),
any daemon cache (dovecot, openldap, gitea, etc.),
and more generally any software that use locking, advanced filesystems features or make any synchronisation assumption.
Ideally, avoid these solutions at all for any serious or production use.
## rclone mount
rclone uses the same configuration when used [in CLI](@/documentation/connect/cli.md) and mount mode.
We suppose you have the following entry in your `rclone.ini` (mine is located in `~/.config/rclone/rclone.conf`):
```toml
[garage]

access_key_id = <access key>
secret_access_key = <secret key>
region = <region>
endpoint = <endpoint>
force_path_style = true
acl = private
bucket_acl = private
```
Then you can mount and access any bucket as follow:
```bash
# mount the bucket
mkdir /tmp/my-bucket
rclone mount --daemon garage:my-bucket /tmp/my-bucket
# set your working directory to the bucket
cd /tmp/my-bucket
# create a file
echo hello world > hello.txt
# access the file
cat hello.txt
# unmount the bucket
cd
fusermount -u /tmp/my-bucket

Whether you need to store and serve binary packages or source code, you may want to deploy a tool referred as a repository or registry.
Garage can also help you serve this content.
| Name | Status | Note |
|------|--------|------|
| [Gitea](#gitea) | ✅ | |
| [Docker](#docker) | ✅ | Requires garage >= v0.6.0 |
| [Nix](#nix) | ✅ | |
| [Gitlab](#gitlab) | ❓ | Not yet tested |
## Gitea
You can use Garage with Gitea to store your [git LFS](https://git-lfs.github.com/) data, your users' avatar, and their attachements.
You can configure a different target for each data type (check `[lfs]` and `[attachment]` sections of the Gitea documentation) and you can provide a default one through the `[storage]` section.
Let's start by creating a key and a bucket (your key id and secret will be needed later, keep them somewhere):
```bash
garage key new --name gitea-key
garage bucket create gitea
garage bucket allow gitea --read --write --key gitea-key
```
Then you can edit your configuration (by default `/etc/gitea/conf/app.ini`):
```ini
[storage]
STORAGE_TYPE=minio
MINIO_ENDPOINT=localhost:3900
MINIO_ACCESS_KEY_ID=GKxxx
MINIO_SECRET_ACCESS_KEY=xxxx
MINIO_BUCKET=gitea
MINIO_LOCATION=garage
MINIO_USE_SSL=false
```
You can also pass this configuration through environment variables:
```bash
GITEA__storage__STORAGE_TYPE=minio
GITEA__storage__MINIO_ENDPOINT=localhost:3900
GITEA__storage__MINIO_ACCESS_KEY_ID=GKxxx
GITEA__storage__MINIO_SECRET_ACCESS_KEY=xxxx
GITEA__storage__MINIO_BUCKET=gitea
GITEA__storage__MINIO_LOCATION=garage
GITEA__storage__MINIO_USE_SSL=false
```
Then restart your gitea instance and try to upload a custom avatar.
If it worked, you should see some content in your gitea bucket (you must configure your `aws` command before):
```
$ aws s3 ls s3://gitea/avatars/
2021-11-10 12:35:47 190034 616ba79ae2b84f565c33d72c2ec50861
```
*External link:* [Gitea Documentation > Configuration Cheat Sheet](https://docs.gitea.io/en-us/config-cheat-sheet/)
## Docker
Create a bucket and a key for your docker registry, then create `config.yml` with the following content:
```yml
version: 0.1
http:
addr: 0.0.0.0:5000
secret: asecretforlocaldevelopment
debug:
addr: localhost:5001
storage:
s3:
accesskey: GKxxxx
secretkey: yyyyy
region: garage
regionendpoint: http://localhost:3900
bucket: docker
secure: false
v4auth: true
rootdirectory: /
```
Replace the `accesskey`, `secretkey`, `bucket`, `regionendpoint` and `secure` values by the one fitting your deployment.
Then simply run the docker registry:
```bash
docker run \
--net=host \
-v `pwd`/config.yml:/etc/docker/registry/config.yml \
registry:2
```
*We started a plain text registry but docker clients require encrypted registries. You must either [setup TLS](https://docs.docker.com/registry/deploying/#run-an-externally-accessible-registry) on your registry or add `--insecure-registry=localhost:5000` to your docker daemon parameters.*
*External link:* [Docker Documentation > Registry storage drivers > S3 storage driver](https://docs.docker.com/registry/storage-drivers/s3/)
## Nix
Nix has no repository in its terminology: instead, it breaks down this concept in 2 parts: binary cache and channel.
**A channel** is a set of `.nix` definitions that generate definitions for all the software you want to serve.
Because we do not want all our clients to compile all these derivations by themselves,
we can compile them once and then serve them as part of our **binary cache**.
It is possible to use a **binary cache** without a channel, you only need to serve your nix definitions
through another support, like a git repository.
As a first step, we will need to create a bucket on Garage and enabling website access on it:
```bash
garage key new --name nix-key
garage bucket create nix.example.com
garage bucket allow nix.example.com --read --write --key nix-key
garage bucket website nix.example.com --allow
```
If you need more information about exposing buckets as websites on Garage,
check [Exposing buckets as websites](@/documentation/cookbook/exposing-websites.md)
and [Configuring a reverse proxy](@/documentation/cookbook/reverse-proxy.md).
Next, we want to check that our bucket works:
```bash
echo nix repo > /tmp/index.html
mc cp /tmp/index.html garage/nix/
rm /tmp/index.html
curl https://nix.example.com
# output: nix repo
```
### Binary cache
To serve binaries as part of your cache, you need to sign them with a key specific to nix.
You can generate the keypair as follow:
```bash
nix-store --generate-binary-cache-key <name> cache-priv-key.pem cache-pub-key.pem
```
You can then manually sign the packages of your store with the following command:
```bash
nix sign-paths --all -k cache-priv-key.pem
```
Setting a key in `nix.conf` will do the signature at build time automatically without additional commands.
Edit the `nix.conf` of your builder:
```toml
secret-key-files = /etc/nix/cache-priv-key.pem
```
Now that your content is signed, you can copy a derivation to your cache.
For example, if you want to copy a specific derivation of your store:
```bash
nix copy /nix/store/wadmyilr414n7bimxysbny876i2vlm5r-bash-5.1-p8 --to 's3://nix?endpoint=garage.example.com&region=garage'
```
*Note that if you have not signed your packages, you can append to the end of your S3 URL `&secret-key=/etc/nix/cache-priv-key.pem`.*
Sometimes you don't want to hardcode this store path in your script.
Let suppose that you are working on a codebase that you build with `nix-build`, you can then run:
```bash
nix copy $(nix-build) --to 's3://nix?endpoint=garage.example.com&region=garage'
```
*This command works because the only thing that `nix-build` outputs on stdout is the paths of the built derivations in your nix store.*
You can include your derivation dependencies:
```bash
nix copy $(nix-store -qR $(nix-build)) --to 's3://nix?endpoint=garage.example.com&region=garage'
```
Now, your binary cache stores your derivation and all its dependencies.
Just inform your users that they must update their `nix.conf` file with the following lines:
```toml
substituters = https://cache.nixos.org https://nix.example.com
trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= nix.example.com:eTGL6kvaQn6cDR/F9lDYUIP9nCVR/kkshYfLDJf1yKs=
```
*You must re-add cache.nixorg.org because redeclaring these keys override the previous configuration instead of extending it.*
Now, when your clients will run `nix-build` or any command that generates a derivation for which a hash is already present
on the binary cache, the client will download the result from the cache instead of compiling it, saving lot of time and CPU!
### Channels
Channels additionnaly serve Nix definitions, ie. a `.nix` file referencing
all the derivations you want to serve.

Garage is also suitable to host static websites.
While they can be deployed with traditional CLI tools, some static website generators have integrated options to ease your workflow.
| Name | Status | Note |
|------|--------|------|
| [Hugo](#hugo) | ✅ | Publishing logic is integrated in the tool |
| [Publii](#publii) | ✅ | Require a correctly configured s3 vhost endpoint |
| [Generic Static Site Generator](#generic-static-site-generator) | ✅ | Works for Jekyll, Zola, Gatsby, Pelican, etc. |
## Hugo
Add to your `config.toml` the following section:
```toml
[[deployment.targets]]
URL = "s3://<bucket>?endpoint=<endpoint>&disableSSL=<bool>&s3ForcePathStyle=true&region=garage"
```
For example:
```toml
[[deployment.targets]]
URL = "s3://my-blog?endpoint=localhost:9000&disableSSL=true&s3ForcePathStyle=true&region=garage"
```
Then inform hugo of your credentials:
```bash
export AWS_ACCESS_KEY_ID=GKxxx
export AWS_SECRET_ACCESS_KEY=xxx
```
And finally build and deploy your website:
```bsh
hugo
hugo deploy
```

## Publii
[![A screenshot of Publii's GUI](./publii.png)](./publii.png)
Deploying a website to Garage from Publii is natively supported.
First, make sure that your Garage administrator allowed and configured Garage to support vhost access style.
We also suppose that your bucket ("my-bucket") and key is already created and configured.
Then, from the left menu, click on server. Choose "S3" as the protocol.
In the configuration window, enter:
- Your finale website URL (eg. "http://my-bucket.web.garage.localhost:3902")
- Tick "Use a custom S3 provider"
- Set the S3 endpoint, (eg. "http://s3.garage.localhost:3900")
- Then put your access key (eg. "GK..."), your secret key, and your bucket (eg. "my-bucket")

Now, each time you want to publish your website from Publii, just hit the bottom left button "Sync your website"!
## Generic Static Site Generator
Some tools do not support sending to a S3 backend but output a compiled folder on your system.
We can then use any CLI tool to upload this content to our S3 target.
First, start by [configuring minio client](@/documentation/connect/cli.md#minio-client).
Then build your website (example for jekyll):
```bash
jekyll build
```
And copy its output folder (`_site` for Jekyll) on S3:
```bash
mc mirror --overwrite _site garage/my-site
```

title = "Exposing buckets as websites"
weight = 25
+++
## Configuring a bucket for website access
There are two 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
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 = "Configuring a gateway node"
weight = 20
+++
Gateways allow you to expose Garage endpoints (S3 API and websites) without storing data on the node.
## Benefits
You can configure Garage as a gateway on all nodes that will consume your S3 API, it will provide you the following benefits:
- **It removes 1 or 2 network RTT.** Instead of (querying your reverse proxy then) querying a random node of the cluster that will forward your request to the nodes effectively storing the data, your local gateway will directly knows which node to query.
- **It eases server management.** Instead of tracking in your reverse proxy and DNS what are the current Garage nodes, your gateway being part of the cluster keeps this information for you. In your software, you will always specify `http://localhost:3900`.
- **It simplifies security.** Instead of having to maintain and renew a TLS certificate, you leverage the Secret Handshake protocol we use for our cluster. The S3 API protocol will be in plain text but limited to your local machine.
## Spawn a Gateway
The instructions are similar to a regular node, the only option that is different is while configuring the node, you must set the `--gateway` parameter:
```bash
garage layout assign --gateway --tag gw1 <node_id>
garage layout show # review the changes you are making
garage layout apply # once satisfied, apply the changes
```
Then use `http://localhost:3900` when a S3 endpoint is required:
```bash
aws --endpoint-url http://127.0.0.1:3900 s3 ls
```
If a newly added gateway node seems to not be working, do a full table resync to ensure that bucket and key list are correctly propagated:
```bash
garage repair -a --yes tables
```

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;
# 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;

It cannot access (read or write) home folders (/home, /root and /run/user), the rest of the filesystem can only be read but not written, only the path seen as /var/lib/garage is writable as seen by the service (mapped to /var/lib/private/garage on your host). Additionnaly, the process can not gain new privileges over time.*
To start the service then automatically enable it at boot:
```bash
sudo systemctl start garage
sudo systemctl enable garage
```
To see if the service is running and to browse its logs:
```bash
sudo systemctl status garage
sudo journalctl -u garage
```
If you want to modify the service file, do not forget to run `systemctl daemon-reload`
to inform `systemd` of your modifications.

With Garage, we wanted to build a software defined storage service that follow the [KISS principle](https://en.wikipedia.org/wiki/KISS_principle),
that is suitable for geo-distributed deployments and more generally that would work well for community hosting (like a Mastodon instance).
In our benchmarks, we aim to quantify how Garage performs on these goals compared to the other available solutions.
## Geo-distribution
The main challenge in a geo-distributed setup is latency between nodes of the cluster.
The more a user request will require intra-cluster requests to complete, the more its latency will increase.
This is especially true for sequential requests: requests that must wait the result of another request to be sent.
We designed Garage without consensus algorithms (eg. Paxos or Raft) to minimize the number of sequential and parallel requests.
This serie of benchmarks quantifies the impact of this design choice.
### On a simple simulated network
We start with a controlled environment, all the instances are running on the same (powerful enough) machine.
To control the network latency, we simulate the network with [mknet](https://git.deuxfleurs.fr/trinity-1686a/mknet) (a tool we developped, based on `tc` and the linux network stack).
To mesure S3 endpoints latency, we use our own tool [s3lat](https://git.deuxfleurs.fr/quentin/s3lat/) to observe only the intra-cluster latency and not some contention on the nodes (CPU, RAM, disk I/O, network bandwidth, etc.).
Compared to other benchmark tools, S3Lat sends only one (small) request at the same time and measures its latency.
We selected 5 standard endpoints that are often in the critical path: ListBuckets, ListObjects, GetObject, PutObject and RemoveObject.
In this first benchmark, we consider 5 instances that are located in a different place each. To simulate the distance, we configure mknet with a RTT between each node of 100 ms +/- 20 ms of jitter. We get the following graph, where the colored bars represent the mean latency while the error bars the minimum and maximum one:
![Comparison of endpoints latency for minio and garage](./endpoint-latency.png)
Compared to garage, minio latency drastically increases on 3 endpoints: GetObject, PutObject, RemoveObject.
We suppose that these requests on minio make transactions over Raft, involving 4 sequential requests: 1) sending the message to the leader, 2) having the leader dispatch it to the other nodes, 3) waiting for the confirmation of followers and finally 4) commiting it. With our current configuration, one Raft transaction will take around 400 ms. GetObject seems to correlate to 1 transaction while PutObject and RemoveObject seems to correlate to 2 or 3. Reviewing minio code would be required to confirm this hypothesis.
Conversely, garage uses an architecture similar to DynamoDB and never require global cluster coordination to answer a request.
Instead, garage can always contact the right node in charge of the requested data, and can answer in as low as one request in the case of GetObject and PutObject. We also observed that Garage latency, while often lower to minio, is more dispersed: garage is still in beta and has not received any performance optimization yet.
As a conclusion, Garage performs well in such setup while minio will be hard to use, especially for interactive use cases.
### On a complex simulated network
This time we consider a more heterogeneous network with 6 servers spread in 3 datacenter, giving us 2 servers per datacenters.
We consider that intra-DC communications are now very cheap with a latency of 0.5ms and without any jitter.
The inter-DC remains costly with the same value as before (100ms +/- 20ms of jitter).
We plot a similar graph as before:
![Comparison of endpoints latency for minio and garage with 6 nodes in 3 DC](./endpoint-latency-dc.png)
This new graph is very similar to the one before, neither minio or garage seems to benefit from this new topology, but they also do not suffer from it.
Considering garage, this is expected: nodes in the same DC are put in the same zone, and then data are spread on different zones for data resiliency and availaibility.
Then, in the default mode, requesting data requires to query at least 2 zones to be sure that we have the most up to date information.
These requests will involve at least one inter-DC communication.
In other words, we prioritize data availability and synchronization over raw performances.
Minio's case is a bit different as by default a minio cluster is not location aware, so we can't explain its performances through location awareness.
*We know that minio has a multi site mode but it is definitely not a first class citizen: data are asynchronously replicated from one minio cluster to another.*
We suppose that, due to the consensus, for many of its requests minio will wait for a response of the majority of the server, also involving inter-DC communications.
As a conclusion, our new topology did not influence garage or minio performances, confirming that in presence of latency, garage is the best fit.
### On a real world deployment
*TODO*
## Performance stability
A storage cluster will encounter different scenario over its life, many of them will not be predictable.
In this context, we argue that, more than peak performances, we should seek predictable and stable performances to ensure data availability.

## Goals and non-goals
Garage is a lightweight geo-distributed data store that implements the
[Amazon S3](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html)
object storage protocole. It enables applications to store large blobs such
as pictures, video, images, documents, etc., in a redundant multi-node
setting. S3 is versatile enough to also be used to publish a static
website.
Garage is an opinionated object storage solutoin, we focus on the following **desirable properties**:
- **Self-contained & lightweight**: works everywhere and integrates well in existing environments to target [hyperconverged infrastructures](https://en.wikipedia.org/wiki/Hyper-converged_infrastructure).
- **Highly resilient**: highly resilient to network failures, network latency, disk failures, sysadmin failures.
- **Simple**: simple to understand, simple to operate, simple to debug.
- **Internet enabled**: made for multi-sites (eg. datacenters, offices, households, etc.) interconnected through regular Internet connections.
We also noted that the pursuit of some other goals are detrimental to our initial goals.
The following has been identified as **non-goals** (if these points matter to you, you should not use Garage):
- **Extreme performances**: high performances constrain a lot the design and the infrastructure; we seek performances through minimalism only.
- **Feature extensiveness**: we do not plan to add additional features compared to the ones provided by the S3 API.
- **Storage optimizations**: erasure coding or any other coding technique both increase the difficulty of placing data and synchronizing; we limit ourselves to duplication.
- **POSIX/Filesystem compatibility**: we do not aim at being POSIX compatible or to emulate any kind of filesystem. Indeed, in a distributed environment, such synchronizations are translated in network messages that impose severe constraints on the deployment.
## Use-cases
*Are you also using Garage in your organization? [Open a PR](https://git.deuxfleurs.fr/Deuxfleurs/garage) to add your use case here!*
### Deuxfleurs
[Deuxfleurs](https://deuxfleurs.fr) is an experimental non-profit hosting
organization that develops Garage. Deuxfleurs is focused on building highly
available infrastructure through redundancy in multiple geographical
locations. They use Garage themselves for the following tasks:
- Hosting of [main website](https://deuxfleurs.fr), [this website](https://garagehq.deuxfleurs.fr), as well as the personal website of many of the members of the organization
- As a [Matrix media backend](https://github.com/matrix-org/synapse-s3-storage-provider)
- To store personal data and shared documents through [Bagage](https://git.deuxfleurs.fr/Deuxfleurs/bagage), a homegrown WebDav-to-S3 proxy
- In the Drone continuous integration platform to store task logs
- As a Nix binary cache
- As a backup target using `rclone`
The Deuxfleurs Garage cluster is a multi-site cluster currently composed of
4 nodes in 2 physical locations. In the future it will be expanded to at
least 3 physical locations to fully exploit Garage's potential for high
availability.

## Garbage collection
A faulty garbage collection procedure has been the cause of
[critical bug #39](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/39).
This precise bug was fixed in the code, however there are potentially more
general issues with the garbage collector being too eager and deleting things
too early. This has been the subject of
[PR #135](https://git.deuxfleurs.fr/Deuxfleurs/garage/pulls/135).
This section summarizes the discussions on this topic.
Rationale: we want to ensure Garage's safety by making sure things don't get
deleted from disk if they are still needed. Two aspects are involved in this.
### 1. Garbage collection of table entries (in `meta/` directory)
The `Entry` trait used for table entries (defined in `tables/schema.rs`)
defines a function `is_tombstone()` that returns `true` if that entry
represents an entry that is deleted in the table. CRDT semantics by default
keep all tombstones, because they are necessary for reconciliation: if node A
has a tombstone that supersedes a value `x`, and node B has value `x`, A has to
keep the tombstone in memory so that the value `x` can be properly deleted at
node `B`. Otherwise, due to the CRDT reconciliation rule, the value `x` from B
would flow back to A and a deleted item would reappear in the system.
Here, we have some control on the nodes involved in storing Garage data.
Therefore we have a garbage collector that is able to delete tombstones UNDER
CERTAIN CONDITIONS. This garbage collector is implemented in `table/gc.rs`. To
delete a tombstone, the following condition has to be met:
- All nodes responsible for storing this entry are aware of the existence of
the tombstone, i.e. they cannot hold another version of the entry that is
superseeded by the tombstone. This ensures that deleting the tombstone is
safe and that no deleted value will come back in the system.
Garage makes use of Sled's atomic operations (such as compare-and-swap and
transactions) to ensure that only tombstones that have been correctly
propagated to other nodes are ever deleted from the local entry tree.
This GC is safe in the following sense: no non-tombstone data is ever deleted
from Garage tables.
**However**, there is an issue with the way this interacts with data
rebalancing in the case when a partition is moving between nodes. If a node has
some data of a partition for which it is not responsible, it has to offload it.
However that offload process takes some time. In that interval, the GC does not
check with that node if it has the tombstone before deleting the tombstone, so
perhaps it doesn't have it and when the offload finally happens, old data comes
back in the system.
**PR 135 mostly fixes this** by implementing a 24-hour delay before anything is
garbage collected in a table. This works under the assumption that rebalances
that follow data shuffling terminate in less than 24 hours.
**However**, in distributed systems, it is generally considered a bad practice
to make assumptions that information propagates in a certain time interval:
this consists in making a synchrony assumption, meaning that we are basically
assuming a computing model that has much stronger properties than otherwise. To
maximize the applicability of Garage, we would like to remove this assumption,
and implement a system where time does not play a role. To do this, we would
need to find a way to safely disable the GC when data is being shuffled around,
and safely detect that the shuffling has terminated and thus the GC can be
resumed. This introduces some complexity to the protocol and hasn't been
tackled yet.
### 2. Garbage collection of data blocks (in `data/` directory)
Blocks in the data directory are reference-counted. In Garage versions before
PR #135, blocks could get deleted from local disk as soon as their reference
counter reached zero. We had a mechanism to not trigger this immediately at the
rc-reaches-zero event, but the cleanup could be triggered by other means (for
example by a block repair operation...). PR #135 added a safety measure so that
blocks never get deleted in a 10 minute interval following the time when the RC
reaches zero. This is a measure to make impossible race conditions such as #39.
We would have liked to use a larger delay (e.g. 24 hours), but in the case of a
rebalance of data, this would have led to the disk utilization to explode
during the rebalancing, only to shrink again after 24 hours. The 10-minute
delay is a compromise that gives good security while not having this problem of
disk space explosion on rebalance.

Values between `1` (faster compression) and `19` (smaller file) are standard compression

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.

title = "Cluster layout management"
weight = 10
+++
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.
An introduction to building cluster layouts can be found in the [production deployment](@/documentation/cookbook/real-world.md) page.
## How cluster layouts work in Garage
In Garage, a cluster layout is composed of the following components:
- a table of roles assigned to nodes
- a version number
Garage nodes will always use the cluster layout with the highest version number.
Garage nodes also maintain and synchronize between them a set of proposed role
changes that haven't yet been applied. These changes will be applied (or
canceled) in the next version of the layout
The following commands insert modifications to the set of proposed role changes
for the next layout version (but they do not create the new layout immediately):
```bash
garage layout assign [...]
garage layout remove [...]
```
The following command can be used to inspect the layout that is currently set in the cluster
and the changes proposed for the next layout version, if any:
```bash
garage layout show
```
The following commands create a new layout with the specified version number,
that either takes into account the proposed changes or cancels them:
```bash
garage layout apply --version <new_version_number>
garage layout revert --version <new_version_number>
```
The version number of the new layout to create must be 1 + the version number
of the previous layout that existed in the cluster. The `apply` and `revert`
commands will fail otherwise.
## Warnings about Garage cluster layout management
**Warning: never make several calls to `garage layout apply` or `garage layout
revert` with the same value of the `--version` flag. Doing so can lead to the
creation of several different layouts with the same version number, in which
case your Garage cluster will become inconsistent until fixed.** If a call to
`garage layout apply` or `garage layout revert` has failed and `garage layout
show` indicates that a new layout with the given version number has not been
set in the cluster, then it is fine to call the command again with the same
version number.
If you are using the `garage` CLI by typing individual commands in your
shell, you shouldn't have much issues as long as you run commands one after
the other and take care of checking the output of `garage layout show`
before applying any changes.
If you are using the `garage` CLI to script layout changes, follow the following recommendations:
- Make all of your `garage` CLI calls to the same RPC host. Do not use the
`garage` CLI to connect to individual nodes to send them each a piece of the
layout changes you are making, as the changes propagate asynchronously
between nodes and might not all be taken into account at the time when the
new layout is applied.
- **Only call `garage layout apply` once**, and call it **strictly after** all
of the `layout assign` and `layout remove` commands have returned.

**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 miss 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) |

### 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) |

**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 Amazon one plus it 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.

*Notes:* Ceph claims that it supports bucket policies but does not implement any Policy endpoints. They probably refer to their own permission system. Riak CS only supports a subset of the policy configuration.
### Versioning, Lifecycle endpoints
Garage does not support (yet) 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").
*Note: Ceph only supports `Expiration`, `NoncurrentVersionExpiration` and `AbortIncompleteMultipartUpload` on its Lifecycle endpoints.*
### 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 though 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.

# Apps (Nextcloud, Peertube...)
In this section, we cover the following software: [Nextcloud](#nextcloud), [Peertube](#peertube), [Mastodon](#mastodon), [Matrix](#matrix)
## Nextcloud
Nextcloud is a popular file synchronisation and backup service.
By default, Nextcloud stores its data on the local filesystem.
If you want to expand your storage to aggregate multiple servers, Garage is the way to go.
A S3 backend can be configured in two ways on Nextcloud, either as Primary Storage or as an External Storage.
Primary storage will store all your data on S3, in an opaque manner, and will provide the best performances.
External storage enable you to select which data will be stored on S3, your file hierarchy will be preserved in S3, but it might be slower.
In the following, we cover both methods but before reading our guide, we suppose you have done some preliminary steps.
First, we expect you have an already installed and configured Nextcloud instance.
Second, we suppose you have created a key and a bucket.
As a reminder, you can create a key for your nextcloud instance as follow:
```bash
garage key new --name nextcloud-key
```
Keep the Key ID and the Secret key in a pad, they will be needed later.
Then you can create a bucket and give read/write rights to your key on this bucket with:
```bash
garage bucket create nextcloud
garage bucket allow nextcloud --read --write --key nextcloud-key
```
### Primary Storage
Now edit your Nextcloud configuration file to enable object storage.
On my installation, the config. file is located at the following path: `/var/www/nextcloud/config/config.php`.
We will add a new root key to the `$CONFIG` dictionnary named `objectstore`:
```php
<?php
$CONFIG = array(
/* your existing configuration */
'objectstore' => [
'class' => '\\OC\\Files\\ObjectStore\\S3',
'arguments' => [
'bucket' => 'nextcloud', // Your bucket name, must be created before
'autocreate' => false, // Garage does not support autocreate
'key' => 'xxxxxxxxx', // The Key ID generated previously
'secret' => 'xxxxxxxxx', // The Secret key generated previously
'hostname' => '127.0.0.1', // Can also be a domain name, eg. garage.example.com
'port' => 3900, // Put your reverse proxy port or your S3 API port
'use_ssl' => false, // Set it to true if you have a TLS enabled reverse proxy
'region' => 'garage', // Garage has only one region named "garage"
'use_path_style' => true // Garage supports only path style, must be set to true
],
],
```
That's all, your Nextcloud will store all your data to S3.
To test your new configuration, just reload your Nextcloud webpage and start sending data.
*External link:* [Nextcloud Documentation > Primary Storage](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/primary_storage.html)
### External Storage
**From the GUI.** Activate the "External storage support" app from the "Applications" page (click on your account icon on the top right corner of your screen to display the menu). Go to your parameters page (also located below your account icon). Click on external storage (or the corresponding translation in your language).
[![Screenshot of the External Storage form](./cli-nextcloud-gui.png)](./cli-nextcloud-gui.png)
*Click on the picture to zoom*
Add a new external storage. Put what you want in "folder name" (eg. "shared"). Select "Amazon S3". Keep "Access Key" for the Authentication field.
In Configuration, put your bucket name (eg. nextcloud), the host (eg. 127.0.0.1), the port (eg. 3900 or 443), the region (garage). Tick the SSL box if you have put an HTTPS proxy in front of garage. You must tick the "Path access" box and you must leave the "Legacy authentication (v2)" box empty. Put your Key ID (eg. GK...) and your Secret Key in the last two input boxes. Finally click on the tick symbol on the right of your screen.
Now go to your "Files" app and a new "linked folder" has appeared with the name you chose earlier (eg. "shared").
*External link:* [Nextcloud Documentation > External Storage Configuration GUI](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage_configuration_gui.html)
**From the CLI.** First install the external storage application:
```bash
php occ app:install files_external
```
Then add a new mount point with:
```bash
php occ files_external:create \
-c bucket=nextcloud \
-c hostname=127.0.0.1 \
-c port=3900 \
-c region=garage \
-c use_ssl=false \
-c use_path_style=true \
-c legacy_auth=false \
-c key=GKxxxx \
-c secret=xxxx \
shared amazons3 amazons3::accesskey
```
Adapt the `hostname`, `port`, `use_ssl`, `key`, and `secret` entries to your configuration.
Do not change the `use_path_style` and `legacy_auth` entries, other configurations are not supported.
*External link:* [Nextcloud Documentation > occ command > files external](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/occ_command.html#files-external-label)
## Peertube
Peertube proposes a clever integration of S3 by directly exposing its endpoint instead of proxifying requests through the application.
In other words, Peertube is only responsible of the "control plane" and offload the "data plane" to Garage.
In return, this system is a bit harder to configure, especially with Garage that supports less feature than other older S3 backends.
We show that it is still possible to configure Garage with Peertube, allowing you to spread the load and the bandiwdth usage on the Garage cluster.
### Enable path-style access by patching Peertube
First, you will need to apply a small patch on Peertube ([#4510](https://github.com/Chocobozzz/PeerTube/pull/4510)):

You can then recompile it with:
```
npm run build
```
And it can be started with:
```
NODE_ENV=production NODE_CONFIG_DIR=/srv/peertube/config node dist/server.js
```
### Create resources in Garage
Create a key for Peertube:
```bash
garage key new --name peertube-key
```
Keep the Key ID and the Secret key in a pad, they will be needed later.
We need two buckets, one for normal videos (named peertube-video) and one for webtorrent videos (named peertube-playlist).
```bash
garage bucket create peertube-video
garage bucket create peertube-playlist
```
Now we allow our key to read and write on these buckets:
```
garage bucket allow peertube-playlist --read --write --key peertube-key
garage bucket allow peertube-video --read --write --key peertube-key
```
Finally, we need to expose these buckets publicly to serve their content to users:
```bash
garage bucket website --allow peertube-playlist
garage bucket website --allow peertube-video
```
These buckets are now accessible on the web port (by default 3902) with the following URL: `http://<bucket><root_domain>:<web_port>` where the root domain is defined in your configuration file (by default `.web.garage`). So we have currently the following URLs:
* http://peertube-playlist.web.garage:3902
* http://peertube-video.web.garage:3902
Make sure you (will) have a corresponding DNS entry for them.
### Configure a Reverse Proxy to serve CORS
Now we will configure a reverse proxy in front of Garage.
This is required as we have no other way to serve CORS headers yet.
For our example, we will use nginx:
```nginx
server {
# In production you should use TLS instead of plain HTTP
listen [::]:80;
server_name peertube-video.web.garage peertube-playlist.web.garage;
location / {
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Max-Age 3600;
add_header Access-Control-Expose-Headers Content-Length;
add_header Access-Control-Allow-Headers Range;
# We do not forward OPTIONS request to Garage
# as it does not know how to interpret them.
# Instead, we simply answers 200.
if ($request_method !~ ^(GET|HEAD)$ ) {
return 200;
}
# If your do not have a Garage instance on the reverse proxy, change the URL here.
proxy_pass http://127.0.0.1:3902;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
}
}
```
Now make sure that your 2 dns entries are pointing to your reverse proxy.
### Configure Peertube
You must edit the file named `config/production.yaml`, we are only modifying the root key named `object_storage`:
```yaml
object_storage:
enabled: true
# Put localhost only if you have a garage instance running on that node
endpoint: 'http://localhost:3900' # or "garage.example.com" if you have TLS on port 443
# This entry has been added by our patch, must be set to true
force_path_style: true
# Garage supports only one region for now, named garage
region: 'garage'
credentials:
access_key_id: 'GKxxxx'
secret_access_key: 'xxxx'
max_upload_part: 2GB
streaming_playlists:
bucket_name: 'peertube-playlist'
# Keep it empty for our example
prefix: ''
# You must fill this field to make Peertube use our reverse proxy/website logic
base_url: 'http://peertube-playlist.web.garage' # Example: 'https://mirror.example.com'
# Same settings but for webtorrent videos
videos:
bucket_name: 'peertube-video'
prefix: ''
# You must fill this field to make Peertube use our reverse proxy/website logic
base_url: 'http://peertube-video.web.garage'
```
### That's all
Everything must be configured now, simply restart Peertube and try to upload a video.
You must see in your browser console that data are fetched directly from our bucket (through the reverse proxy).
### Miscellaneous
*Known bug:* The playback does not start and some 400 Bad Request Errors appear in your browser console and on Garage.
If the description of the error contains HTTP Invalid Range: InvalidRange, the error is due to a buggy ffmpeg version.
You must avoid the 4.4.0 and use either a newer or older version.
*Associated issues:* [#137](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/137), [#138](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/138), [#140](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/140). These issues are non blocking.

# CLI tools
CLI tools allow you to query the S3 API without too many abstractions.
These tools are particularly suitable for debug, backups, website deployments or any scripted task that need to handle data.
## Minio client (recommended)
Use the following command to set an "alias", i.e. define a new S3 server to be
used by the Minio client:
```bash
mc alias set \
garage \
<endpoint> \
<access key> \
<secret key> \
--api S3v4
```
Remember that `mc` is sometimes called `mcli` (such as on Arch Linux), to avoid conflicts
with Midnight Commander.
Some commands:
```bash
# list buckets
mc ls garage/
# list objets in a bucket
mc ls garage/my_files
# copy from your filesystem to garage
mc cp /proc/cpuinfo garage/my_files/cpuinfo.txt
# copy from garage to your filesystem
mc cp garage/my_files/cpuinfo.txt /tmp/cpuinfo.txt
# mirror a folder from your filesystem to garage
mc mirror --overwrite ./book garage/garagehq.deuxfleurs.fr
```
## AWS CLI
Create a file named `~/.aws/credentials` and put:
```toml
[default]
aws_access_key_id=xxxx
aws_secret_access_key=xxxx
```
Then a file named `~/.aws/config` and put:
```toml
[default]
region=garage
```
Now, supposing Garage is listening on `http://127.0.0.1:3900`, you can list your buckets with:
```bash
aws --endpoint-url http://127.0.0.1:3900 s3 ls
```
Passing the `--endpoint-url` parameter to each command is annoying but AWS developers do not provide a corresponding configuration entry.
As a workaround, you can redefine the aws command by editing the file `~/.bashrc`:
```
function aws { command aws --endpoint-url http://127.0.0.1:3900 $@ ; }
```
*Do not forget to run `source ~/.bashrc` or to start a new terminal before running the next commands.*
Now you can simply run:
```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
```
## `rclone`
`rclone` can be configured using the interactive assistant invoked using `rclone configure`.
You can also configure `rclone` by writing directly its configuration file.
Here is a template `rclone.ini` configuration file:
```ini
[garage]
type = s3
provider = Other
env_auth = false
access_key_id = <access key>
secret_access_key = <secret key>
region = <region>
endpoint = <endpoint>
force_path_style = true
acl = private
bucket_acl = private
```
## Cyberduck
TODO
## `s3cmd`
Here is a template for the `s3cmd.cfg` file to talk with Garage:
```ini
[default]
access_key = <access key>
secret_key = <secret key>
host_base = <endpoint without http(s)://>
host_bucket = <same as host_base>
use_https = False | True
```

steps to deploy Garage in a real-world setting.
- **[Configuring S3 clients](clients.md):** This page will explain how to configure
popular S3 clients to interact with a Garage server.
- **[Hosting a website](website.md):** This page explains how to use Garage
to host a static website.
- **[Recovering from failures](recovering.md):** Garage's first selling point is resilience
to hardware failures. This section explains how to recover from such a failure in the
best possible way.
- **[Building from source](from_source.md):** This page explains how to build Garage from
source in case a binary is not provided for your architecture, or if you want to

# Starting Garage with systemd instead of Docker
NOTE: This guide is incomplete. Typicall you would also want to create a separate
Unix user to run Garage.
Make sure you have the Garage binary installed on your system (see [quick start](../quick_start/index.md)), e.g. at `/usr/local/bin/garage`.
Create a file named `/etc/systemd/system/garage.service`:
```toml
[Unit]
Description=Garage Data Store
After=network-online.target
Wants=network-online.target
[Service]
Environment='RUST_LOG=garage=info' 'RUST_BACKTRACE=1'
ExecStart=/usr/local/bin/garage server -c /etc/garage/garage.toml
[Install]
WantedBy=multi-user.target
```
To start the service then automatically enable it at boot:
```bash
sudo systemctl start garage
sudo systemctl enable garage
```
To see if the service is running and to browse its logs:
```bash
sudo systemctl status garage
sudo journalctl -u garage
```
If you want to modify the service file, do not forget to run `systemctl daemon-reload`
to inform `systemd` of your modifications.

# The Garage Geo-Distributed Data Store
Garage is a lightweight geo-distributed data store.
It comes from the observation that despite numerous object stores
many people have broken data management policies (backup/replication on a single site or none at all).
To promote better data management policies, we focused on the following **desirable properties**:
- **Self-contained & lightweight**: works everywhere and integrates well in existing environments to target [hyperconverged infrastructures](https://en.wikipedia.org/wiki/Hyper-converged_infrastructure).
- **Highly resilient**: highly resilient to network failures, network latency, disk failures, sysadmin failures.
- **Simple**: simple to understand, simple to operate, simple to debug.
- **Internet enabled**: made for multi-sites (eg. datacenters, offices, households, etc.) interconnected through regular Internet connections.
We also noted that the pursuit of some other goals are detrimental to our initial goals.
The following has been identified as **non-goals** (if these points matter to you, you should not use Garage):
- **Extreme performances**: high performances constrain a lot the design and the infrastructure; we seek performances through minimalism only.
- **Feature extensiveness**: complete implementation of the S3 API or any other API to make garage a drop-in replacement is not targeted as it could lead to decisions impacting our desirable properties.
- **Storage optimizations**: erasure coding or any other coding technique both increase the difficulty of placing data and synchronizing; we limit ourselves to duplication.
- **POSIX/Filesystem compatibility**: we do not aim at being POSIX compatible or to emulate any kind of filesystem. Indeed, in a distributed environment, such synchronizations are translated in network messages that impose severe constraints on the deployment.
## Supported and planned protocols
Garage speaks (or will speak) the following protocols:
- [S3](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html) - *SUPPORTED* - Enable applications to store large blobs such as pictures, video, images, documents, etc. S3 is versatile enough to also be used to publish a static website.
- [IMAP](https://github.com/go-pluto/pluto) - *PLANNED* - email storage is quite complex to get good performances.
To keep performances optimal, most IMAP servers only support on-disk storage.
We plan to add logic to Garage to make it a viable solution for email storage.
- *More to come*
## Use Cases
**[Deuxfleurs](https://deuxfleurs.fr):** Garage is used by Deuxfleurs which is a non-profit hosting organization.
Especially, it is used to host their main website, this documentation and some of its members' blogs.
Additionally, Garage is used as a [backend for Nextcloud](https://docs.nextcloud.com/server/20/admin_manual/configuration_files/primary_storage.html).
Deuxfleurs also plans to use Garage as their [Matrix's media backend](https://github.com/matrix-org/synapse-s3-storage-provider) and as the backend of [OCIS](https://github.com/owncloud/ocis).

## Comparison to existing software
**[MinIO](https://min.io/):** MinIO shares our *Self-contained & lightweight* goal but selected two of our non-goals: *Storage optimizations* through erasure coding and *POSIX/Filesystem compatibility* through strong consistency.
However, by pursuing these two non-goals, MinIO do not reach our desirable properties.
Firstly, it fails on the *Simple* property: due to the erasure coding, MinIO has severe limitations on how drives can be added or deleted from a cluster.
Secondly, it fails on the *Internet enabled* property: due to its strong consistency, MinIO is latency sensitive.
Furthermore, MinIO has no knowledge of "sites" and thus can not distribute data to minimize the failure of a given site.
**[Openstack Swift](https://docs.openstack.org/swift/latest/):**
OpenStack Swift at least fails on the *Self-contained & lightweight* goal.
Starting it requires around 8GB of RAM, which is too much especially in an hyperconverged infrastructure.
We also do not classify Swift as *Simple*.
**[Ceph](https://ceph.io/ceph-storage/object-storage/):**
This review holds for the whole Ceph stack, including the RADOS paper, Ceph Object Storage module, the RADOS Gateway, etc.
At its core, Ceph has been designed to provide *POSIX/Filesystem compatibility* which requires strong consistency, which in turn
makes Ceph latency-sensitive and fails our *Internet enabled* goal.
Due to its industry oriented design, Ceph is also far from being *Simple* to operate and from being *Self-contained & lightweight* which makes it hard to integrate it in an hyperconverged infrastructure.
In a certain way, Ceph and MinIO are closer together than they are from Garage or OpenStack Swift.
*More comparisons are available in our [Related Work](design/related_work.md) chapter.*

# S3 Compatibility status
## Global S3 features
Implemented:
- path-style URLs (`garage.tld/bucket/key`)
- putting and getting objects in buckets
- multipart uploads
- listing objects
- access control on a per-key-per-bucket basis
Not implemented:
- vhost-style URLs (`bucket.garage.tld/key`)
- object-level ACL
- object versioning
- encryption
- most `x-amz-` headers
## Endpoint implementation
All APIs that are not mentionned are not implemented and will return a 400 bad request.

| HeadBucket | Implemented |
| HeadObject | Implemented |
| ListBuckets | Implemented |
| ListObjects | Implemented, bugs? (see below) |
| ListObjectsV2 | Implemented |
| PutObject | Implemented |
| UploadPart | Implemented |
- **CreateBucket:** Garage does not yet accept creating buckets or giving access using API calls, it has to be done using the CLI tools. CreateBucket will return a 200 if the bucket exists and user has write access, and a 403 Forbidden in all other cases.
- **DeleteBucket:** Garage does not yet accept deleting buckets using API calls, it has to be done using the CLI tools. This request will return a 403 Forbidden.
- **GetBucketVersioning:** Stub implementation (Garage does not yet support versionning so this always returns
"versionning not enabled").
- **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.

**This guide explains how to migrate to 0.6 if you have an existing 0.5 cluster.
We don't recommend trying to migrate directly from 0.4 or older to 0.6.**
**We make no guarantee that this migration will work perfectly:
back up all your data before attempting it!**
Garage v0.6 (not yet released) introduces a new data model for buckets,
that allows buckets to have many names (aliases).
Buckets can also have "private" aliases (called local aliases),
which are only visible when using a certain access key.
This new data model means that the metadata tables have changed quite a bit in structure,
and a manual migration step is required.
The migration steps are as follows:
1. Disable api and web access for some time (Garage does not support disabling
these endpoints but you can change the port number or stop your reverse
proxy for instance).
2. Do `garage repair -a --yes tables` and `garage repair -a --yes blocks`,
check the logs and check that all data seems to be synced correctly between
nodes.
4. Turn off Garage 0.5
5. **Backup your metadata folders!!**
6. Turn on Garage 0.6
7. At this point, `garage bucket list` should indicate that no buckets are present
in the cluster. `garage key list` should show all of the previously existing
access key, however these keys should not have any permissions to access buckets.
8. Run `garage migrate buckets050`: this will populate the new bucket table with
the buckets that existed previously. This will also give access to API keys
as it was before.
9. Do `garage repair -a --yes tables` and `garage repair -a --yes blocks`,
check the logs and check that all data seems to be synced correctly between
nodes.
10. Check that all your buckets indeed appear in `garage bucket list`, and that
keys have the proper access flags set. If that is not the case, revert
everything and file a bug!
11. Your upgraded cluster should be in a working state. Re-enable API and Web
access and check that everything went well.
