# Quick Start
|
|
|
|
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.
|
|
|
|
Our goal is to introduce you to Garage's workflows.
|
|
Following this guide is recommended before moving on to
|
|
[configuring a multi-node cluster](../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/_releases.html>
|
|
|
|
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](../cookbook/from_source.md).
|
|
|
|
|
|
## Writing a first configuration file
|
|
|
|
This first configuration file should allow you to get started easily with the simplest
|
|
possible Garage deployment.
|
|
**Save it as `/etc/garage.toml`.**
|
|
You can also store it somewhere else, but you will have to specify `-c path/to/garage.toml`
|
|
at each invocation of the `garage` binary (for example: `garage -c ./garage.toml server`, `garage -c ./garage.toml status`).
|
|
|
|
```toml
|
|
metadata_dir = "/tmp/meta"
|
|
data_dir = "/tmp/data"
|
|
|
|
replication_mode = "none"
|
|
|
|
rpc_bind_addr = "[::]:3901"
|
|
rpc_public_addr = "127.0.0.1:3901"
|
|
rpc_secret = "1799bccfd7411eddcf9ebd316bc1f5287ad12a68094e1c6ac6abde7e6feae1ec"
|
|
|
|
bootstrap_peers = []
|
|
|
|
[s3_api]
|
|
s3_region = "garage"
|
|
api_bind_addr = "[::]:3900"
|
|
root_domain = ".s3.garage"
|
|
|
|
[s3_web]
|
|
bind_addr = "[::]:3902"
|
|
root_domain = ".web.garage"
|
|
index = "index.html"
|
|
```
|
|
|
|
The `rpc_secret` value provided above is just an example. It will work, but in
|
|
order to secure your cluster you will need to use another one. You can generate
|
|
such a value with `openssl rand -hex 32`.
|
|
|
|
|
|
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:
|
|
|
|
```
|
|
RUST_LOG=garage=info 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 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 \
|
|
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
|
|
|
|
We recommend the use of MinIO Client to interact with Garage files (`mc`).
|
|
Instructions to install it and use it are provided on the
|
|
[MinIO website](https://docs.min.io/docs/minio-client-quickstart-guide.html).
|
|
Before reading the following, you need a working `mc` command on your path.
|
|
|
|
Note that on certain Linux distributions such as Arch Linux, the Minio client binary
|
|
is called `mcli` instead of `mc` (to avoid name clashes with the Midnight Commander).
|
|
|
|
#### Configure `mc`
|
|
|
|
You need your access key and secret key created above.
|
|
We will assume you are invoking `mc` on the same machine as the Garage server,
|
|
your S3 API endpoint is therefore `http://127.0.0.1:3900`.
|
|
For this whole configuration, you must set an alias name: we chose `my-garage`, that you will used for all commands.
|
|
|
|
Adapt the following command accordingly and run it:
|
|
|
|
```bash
|
|
mc alias set \
|
|
my-garage \
|
|
http://127.0.0.1:3900 \
|
|
<access key> \
|
|
<secret key> \
|
|
--api S3v4
|
|
```
|
|
|
|
You must also add an environment variable to your configuration to
|
|
inform MinIO of our region (`garage` by default, corresponding to the `s3_region` parameter
|
|
in the configuration file).
|
|
The best way is to add the following snippet to your `$HOME/.bash_profile`
|
|
or `$HOME/.bashrc` file:
|
|
|
|
```bash
|
|
export MC_REGION=garage
|
|
```
|
|
|
|
#### Use `mc`
|
|
|
|
You can not list buckets from `mc` currently.
|
|
|
|
But the following commands and many more should work:
|
|
|
|
```bash
|
|
mc cp image.png my-garage/nextcloud-bucket
|
|
mc cp my-garage/nextcloud-bucket/image.png .
|
|
mc ls my-garage/nextcloud-bucket
|
|
mc mirror localdir/ my-garage/another-bucket
|
|
```
|
|
|
|
|
|
#### Other tools for interacting with Garage
|
|
|
|
The following tools can also be used to send and recieve files from/to Garage:
|
|
|
|
- the [AWS CLI](https://aws.amazon.com/cli/)
|
|
- [`rclone`](https://rclone.org/)
|
|
- [Cyberduck](https://cyberduck.io/)
|
|
- [`s3cmd`](https://s3tools.org/s3cmd)
|
|
|
|
Refer to the ["Integrations" section](../connect/index.md) to learn how to
|
|
configure application and command line utilities to integrate with Garage.
