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:
|
|
|
|
- [Goals and use cases](@/documentation/design/goals.md)
|
|
- [List of features](@/documentation/reference-manual/features.md)
|
|
|
|
## Scope of this tutorial
|
|
|
|
Our goal is to introduce you to Garage's workflows.
|
|
Following this guide is recommended before moving on to
|
|
[configuring a multi-node cluster](@/documentation/cookbook/real-world.md).
|
|
|
|
Note that this kind of deployment should not be used in production,
|
|
as it provides no redundancy for your data!
|
|
|
|
## Get a binary
|
|
|
|
Download the latest Garage binary from the release pages on our repository:
|
|
|
|
<https://garagehq.deuxfleurs.fr/download/>
|
|
|
|
Place this binary somewhere in your `$PATH` so that you can invoke the `garage`
|
|
command directly (for instance you can copy the binary in `/usr/local/bin`
|
|
or in `~/.local/bin`).
|
|
|
|
If a binary of the last version is not available for your architecture,
|
|
or if you want a build customized for your system,
|
|
you can [build Garage from source](@/documentation/cookbook/from-source.md).
|
|
|
|
|
|
## Configuring and starting Garage
|
|
|
|
### Generating a first configuration file
|
|
|
|
This first configuration file should allow you to get started easily with the simplest
|
|
possible Garage deployment.
|
|
|
|
We will create it with the following command line
|
|
to generate unique and private secrets for security reasons:
|
|
|
|
```bash
|
|
cat > garage.toml <<EOF
|
|
metadata_dir = "/tmp/meta"
|
|
data_dir = "/tmp/data"
|
|
db_engine = "lmdb"
|
|
|
|
replication_mode = "none"
|
|
|
|
rpc_bind_addr = "[::]:3901"
|
|
rpc_public_addr = "127.0.0.1:3901"
|
|
rpc_secret = "$(openssl rand -hex 32)"
|
|
|
|
[s3_api]
|
|
s3_region = "garage"
|
|
api_bind_addr = "[::]:3900"
|
|
root_domain = ".s3.garage.localhost"
|
|
|
|
[s3_web]
|
|
bind_addr = "[::]:3902"
|
|
root_domain = ".web.garage.localhost"
|
|
index = "index.html"
|
|
|
|
[k2v_api]
|
|
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`.**
|
|
|
|
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
|
|
Garage server will not be persistent. Change these to locations on your local disk if you want
|
|
your data to be persisted properly.
|
|
|
|
|
|
### Launching the Garage server
|
|
|
|
Use the following command to launch the Garage server with our configuration file:
|
|
|
|
```
|
|
garage server
|
|
```
|
|
|
|
You can tune Garage's verbosity as follows (from less verbose to more verbose):
|
|
|
|
```
|
|
RUST_LOG=garage=info garage server
|
|
RUST_LOG=garage=debug garage server
|
|
RUST_LOG=garage=trace garage server
|
|
```
|
|
|
|
Log level `info` is the default value and is recommended for most use cases.
|
|
Log level `debug` can help you check why your S3 API calls are not working.
|
|
|
|
|
|
### Checking that Garage runs correctly
|
|
|
|
The `garage` utility is also used as a CLI tool to configure your Garage deployment.
|
|
It uses values from the TOML configuration file to find the Garage daemon running on the
|
|
local node, therefore if your configuration file is not at `/etc/garage.toml` you will
|
|
again have to specify `-c path/to/garage.toml`.
|
|
|
|
If the `garage` CLI is able to correctly detect the parameters of your local Garage node,
|
|
the following command should be enough to show the status of your cluster:
|
|
|
|
```
|
|
garage status
|
|
```
|
|
|
|
This should show something like this:
|
|
|
|
```
|
|
==== HEALTHY NODES ====
|
|
ID Hostname Address Tag Zone Capacity
|
|
563e1ac825ee3323… linuxbox 127.0.0.1:3901 NO ROLE ASSIGNED
|
|
```
|
|
|
|
## Creating a cluster layout
|
|
|
|
Creating a cluster layout for a Garage deployment means informing Garage
|
|
of the disk space available on each node of the cluster
|
|
as well as the zone (e.g. datacenter) each machine is located in.
|
|
|
|
For our test deployment, we are using only one node. The way in which we configure
|
|
it does not matter, you can simply write:
|
|
|
|
```bash
|
|
garage layout assign -z dc1 -c 1 <node_id>
|
|
```
|
|
|
|
where `<node_id>` corresponds to the identifier of the node shown by `garage status` (first column).
|
|
You can enter simply a prefix of that identifier.
|
|
For instance here you could write just `garage layout assign -z dc1 -c 1 563e`.
|
|
|
|
The layout then has to be applied to the cluster, using:
|
|
|
|
```bash
|
|
garage layout apply
|
|
```
|
|
|
|
|
|
## Creating buckets and keys
|
|
|
|
In this section, we will suppose that we want to create a bucket named `nextcloud-bucket`
|
|
that will be accessed through a key named `nextcloud-app-key`.
|
|
|
|
Don't forget that `help` command and `--help` subcommands can help you anywhere,
|
|
the CLI tool is self-documented! Two examples:
|
|
|
|
```
|
|
garage help
|
|
garage bucket allow --help
|
|
```
|
|
|
|
### Create a bucket
|
|
|
|
Let's take an example where we want to deploy NextCloud using Garage as the
|
|
main data storage.
|
|
|
|
First, create a bucket with the following command:
|
|
|
|
```
|
|
garage bucket create nextcloud-bucket
|
|
```
|
|
|
|
Check that everything went well:
|
|
|
|
```
|
|
garage bucket list
|
|
garage bucket info nextcloud-bucket
|
|
```
|
|
|
|
### Create an API key
|
|
|
|
The `nextcloud-bucket` bucket now exists on the Garage server,
|
|
however it cannot be accessed until we add an API key with the proper access rights.
|
|
|
|
Note that API keys are independent of buckets:
|
|
one key can access multiple buckets, multiple keys can access one bucket.
|
|
|
|
Create an API key using the following command:
|
|
|
|
```
|
|
garage key new --name nextcloud-app-key
|
|
```
|
|
|
|
The output should look as follows:
|
|
|
|
```
|
|
Key name: nextcloud-app-key
|
|
Key ID: GK3515373e4c851ebaad366558
|
|
Secret key: 7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34
|
|
Authorized buckets:
|
|
```
|
|
|
|
Check that everything works as intended:
|
|
|
|
```
|
|
garage key list
|
|
garage key info nextcloud-app-key
|
|
```
|
|
|
|
### Allow a key to access a bucket
|
|
|
|
Now that we have a bucket and a key, we need to give permissions to the key on the bucket:
|
|
|
|
```
|
|
garage bucket allow \
|
|
--read \
|
|
--write \
|
|
--owner \
|
|
nextcloud-bucket \
|
|
--key nextcloud-app-key
|
|
```
|
|
|
|
You can check at any time the allowed keys on your bucket with:
|
|
|
|
```
|
|
garage bucket info nextcloud-bucket
|
|
```
|
|
|
|
|
|
## Uploading and downlading from Garage
|
|
|
|
To download and upload files on garage, we can use a third-party tool named `awscli`.
|
|
|
|
|
|
### Install and configure `awscli`
|
|
|
|
If you have python on your system, you can install it with:
|
|
|
|
```bash
|
|
python -m pip install --user awscli
|
|
```
|
|
|
|
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:
|
|
|
|
```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
|
|
```
|
|
|
|
Now, each time you want to use `awscli` on this target, run:
|
|
|
|
```bash
|
|
source ~/.awsrc
|
|
```
|
|
|
|
*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://nextcloud-bucket
|
|
|
|
# copy from your filesystem to garage
|
|
aws s3 cp /proc/cpuinfo s3://nextcloud-bucket/cpuinfo.txt
|
|
|
|
# copy from garage to your filesystem
|
|
aws s3 cp s3://nextcloud-bucket/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.
|
|

|
|
|
|
Some features are however not implemented like ACL or policy.
|
|
