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

# Deploying Garage on a real-world cluster
To run Garage in cluster mode, we recommend having at least 3 nodes.
This will allow you to setup Garage for three-way replication of your data,
the safest and most available mode avaialble.
We recommend first following the [quick start guide](../quick_start/index.md) in order
to get familiar with Garage's command line and usage patterns.
## Get a Docker image
Our docker image is currently named `lxpz/garage_amd64` and is stored on the [Docker Hub](https://hub.docker.com/r/lxpz/garage_amd64/tags?page=1&ordering=last_updated).
We encourage you to use a fixed tag (eg. `v0.3.0`) and not the `latest` tag.
For this example, we will use the latest published version at the time of the writing which is `v0.3.0` but it's up to you
to check [the most recent versions on the Docker Hub](https://hub.docker.com/r/lxpz/garage_amd64/tags?page=1&ordering=last_updated).
For example:
```
sudo docker pull lxpz/garage_amd64:v0.3.0
```
## Generating TLS certificates
You first need to generate TLS certificates to encrypt traffic between Garage nodes
(reffered to as RPC traffic).
To generate your TLS certificates, run on your machine:
```
wget https://git.deuxfleurs.fr/Deuxfleurs/garage/raw/branch/main/genkeys.sh
chmod +x genkeys.sh
./genkeys.sh
```
It will creates a folder named `pki/` containing the keys that you will used for the cluster.
## Deploying and configuring Garage
To run a real-world deployment, make sure you the following conditions are met:
- You have at least three machines with sufficient storage space available
- Each machine has a public IP address which is reachable by other machines.
Running behind a NAT is possible, but having several Garage nodes behind a single NAT
is slightly more involved as each will have to have a different RPC port number
(the local port number of a node must be the same as the port number exposed publicly
by the NAT).
- Ideally, each machine should have a SSD available in addition to the HDD you are dedicating
to Garage. This will allow for faster access to metadata and has the potential
to drastically reduce Garage's response times.
Before deploying garage on your infrastructure, you must inventory your machines.
For our example, we will suppose the following infrastructure with IPv6 connectivity:
| Location | Name | IP Address | Disk Space |
|----------|---------|------------|------------|
| Paris | Mercury | fc00:1::1 | 1 To |
| Paris | Venus | fc00:1::2 | 2 To |
| London | Earth | fc00:B::1 | 2 To |
| Brussels | Mars | fc00:F::1 | 1.5 To |
On each machine, we will have a similar setup,
especially you must consider the following folders/files:
- `/etc/garage/garage.toml`: Garage daemon's configuration (see below)
- `/etc/garage/pki/`: Folder containing Garage certificates, must be generated on your computer and copied on the servers
- `/var/lib/garage/meta/`: Folder containing Garage's metadata, put this folder on a SSD if possible
- `/var/lib/garage/data/`: Folder containing Garage's data, this folder will grows and must be on a large storage, possibly big HDDs.
- `/etc/systemd/system/garage.service`: Service file to start garage at boot automatically (defined below, not required if you use docker)
A valid `/etc/garage/garage.toml` for our cluster would be:
```toml
metadata_dir = "/var/lib/garage/meta"
data_dir = "/var/lib/garage/data"
replication_mode = "3"
rpc_bind_addr = "[::]:3901"
bootstrap_peers = [
"[fc00:1::1]:3901",
"[fc00:1::2]:3901",
"[fc00:B::1]:3901",
"[fc00:F::1]:3901",
]
[rpc_tls]
ca_cert = "/etc/garage/pki/garage-ca.crt"
node_cert = "/etc/garage/pki/garage.crt"
node_key = "/etc/garage/pki/garage.key"
[s3_api]
s3_region = "garage"
api_bind_addr = "[::]:3900"
[s3_web]
bind_addr = "[::]:3902"
root_domain = ".web.garage"
index = "index.html"
```
Please make sure to change `bootstrap_peers` to **your** IP addresses!
Check the [configuration file reference documentation](../reference_manual/configuration.md)
to learn more about all available configuration options.
## Starting Garage using Docker
On each machine, you can run the daemon with:
```bash
docker run \
-d \
--name garaged \
--restart always \
--network host \
-v /etc/garage/pki:/etc/garage/pki \
-v /etc/garage/garage.toml:/garage/garage.toml \
-v /var/lib/garage/meta:/var/lib/garage/meta \
-v /var/lib/garage/data:/var/lib/garage/data \
lxpz/garage_amd64:v0.3.0
```
It should be restart automatically at each reboot.
Please note that we use host networking as otherwise Docker containers
can not communicate with IPv6.
Upgrading between Garage versions should be supported transparently,
but please check the relase notes before doing so!
To upgrade, simply stop and remove this container and
start again the command with a new version of garage.
## Controling the daemon
The `garage` binary has two purposes:
- it acts as a daemon when launched with `garage server ...`
- it acts as a control tool for the daemon when launched with any other command
In this section, we will see how to use the `garage` binary as a control tool for the daemon we just started.
You first need to get a shell having access to this binary. For instance, enter the Docker container with:
```bash
sudo docker exec -ti garaged bash
```
You will now have a shell where the Garage binary is available as `/garage/garage`
*You can also install the binary on your machine to remotely control the cluster.*
## Talk to the daemon and create an alias
`garage` requires 4 options to talk with the daemon:
```
--ca-cert <ca-cert>
--client-cert <client-cert>
--client-key <client-key>
-h, --rpc-host <rpc-host>
```
The 3 first ones are certificates and keys needed by TLS, the last one is simply the address of garage's RPC endpoint.
If you are invoking `garage` from a server node directly, you do not need to set `--rpc-host`
as the default value `127.0.0.1:3901` will allow it to contact Garage correctly.
To avoid typing the 3 first options each time we want to run a command,
you can use the following alias:
```bash
alias garagectl='/garage/garage \
--ca-cert /etc/garage/pki/garage-ca.crt \
--client-cert /etc/garage/pki/garage.crt \
--client-key /etc/garage/pki/garage.key'
```
You can now use all of the commands presented in the [quick start guide](../quick_start/index.md),
simply replace occurences of `garage` by `garagectl`.
#### Test the alias
You can test your alias by running a simple command such as:
```
garagectl status
```
You should get something like that as result:
```
Healthy nodes:
2a638ed6c775b69a… 37f0ba978d27 [::ffff:172.20.0.101]:3901 UNCONFIGURED/REMOVED
68143d720f20c89d… 9795a2f7abb5 [::ffff:172.20.0.103]:3901 UNCONFIGURED/REMOVED
8781c50c410a41b3… 758338dde686 [::ffff:172.20.0.102]:3901 UNCONFIGURED/REMOVED
```
## Configuring a cluster
We will now inform garage of the disk space available on each node of the cluster
as well as the zone (e.g. datacenter) in which each machine is located.
For our example, we will suppose we have the following infrastructure (Capacity, Identifier and Datacenter are specific values to garage described in the following):
| Location | Name | Disk Space | `Capacity` | `Identifier` | `Zone` |
|----------|---------|------------|------------|--------------|--------------|
| Paris | Mercury | 1 To | `2` | `8781c5` | `par1` |
| Paris | Venus | 2 To | `4` | `2a638e` | `par1` |
| London | Earth | 2 To | `4` | `68143d` | `lon1` |
| Brussels | Mars | 1.5 To | `3` | `212f75` | `bru1` |
#### Node identifiers
After its first launch, garage generates a random and unique identifier for each nodes, such as:
```
8781c50c410a41b363167e9d49cc468b6b9e4449b6577b64f15a249a149bdcbc
```
Often a shorter form can be used, containing only the beginning of the identifier, like `8781c5`,
which identifies the server "Mercury" located in "Paris" according to our previous table.
The most simple way to match an identifier to a node is to run:
```
garagectl status
```
It will display the IP address associated with each node; from the IP address you will be able to recognize the node.
#### Zones
Zones are simply a user-chosen identifier that identify a group of server that are grouped together logically.
It is up to the system administrator deploying garage to identify what does "grouped together" means.
In most cases, a zone will correspond to a geographical location (i.e. a datacenter).
Behind the scene, Garage will use zone definition to try to store the same data on different zones,
in order to provide high availability despite failure of a zone.
#### Capacity
Garage reasons on an arbitrary metric about disk storage that is named the *capacity* of a node.
The capacity configured in Garage must be proportional to the disk space dedicated to the node.
Additionaly, the capacity values used in Garage should be as small as possible, with
1 ideally representing the size of your smallest server.
Here we chose that 1 unit of capacity = 0.5 To, so that we can express servers of size
1 To and 2 To, as wel as the intermediate size 1.5 To.
Note that the amount of data stored by Garage on each server may not be strictly proportional to
its capacity value, as Garage will priorize having 3 copies of data in different zones,
even if this means that capacities will not be strictly respected. For example in our above examples,
nodes Earth and Mars will always store a copy of everything each, and the third copy will
have 66% chance of being stored by Venus and 33% chance of being stored by Mercury.
#### Injecting the topology
Given the information above, we will configure our cluster as follow:
```
garagectl node configure -z par1 -c 2 -t mercury 8781c5
garagectl node configure -z par1 -c 4 -t venus 2a638e
garagectl node configure -z lon1 -c 4 -t earth 68143d
garagectl node configure -z bru1 -c 3 -t mars 212f75
```

# 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.

# Get a binary
Currently, only two installations procedures are supported for Garage: from Docker (x86\_64 for Linux) and from source.
In the future, we plan to add a third one, by publishing a compiled binary (x86\_64 for Linux).
We did not test other architecture/operating system but, as long as your architecture/operating system is supported by Rust, you should be able to run Garage (feel free to report your tests!).
## From Docker
Our docker image is currently named `lxpz/garage_amd64` and is stored on the [Docker Hub](https://hub.docker.com/r/lxpz/garage_amd64/tags?page=1&ordering=last_updated).
We encourage you to use a fixed tag (eg. `v0.3.0`) and not the `latest` tag.
For this example, we will use the latest published version at the time of the writing which is `v0.3.0` but it's up to you
to check [the most recent versions on the Docker Hub](https://hub.docker.com/r/lxpz/garage_amd64/tags?page=1&ordering=last_updated).
For example:
```
sudo docker pull lxpz/garage_amd64:v0.3.0
```
## From source
Garage is a standard Rust project.
First, you need `rust` and `cargo`.
On Debian:
```bash
sudo apt-get update
sudo apt-get install -y rustc cargo
```
Then, you can ask cargo to install the binary for you:
```bash
cargo install garage
```
That's all, `garage` should be in `$HOME/.cargo/bin`.
You can add this folder to your `$PATH` or copy the binary somewhere else on your system.
For the following, we will assume you copied it in `/usr/local/bin/garage`:
```bash
sudo cp $HOME/.cargo/bin/garage /usr/local/bin/garage
```

# Configuring a test deployment
This section describes how to run a simple test Garage deployment with a single node.
Note that this kind of deployment should not be used in production, as it provides
no redundancy for your data!
We will also skip intra-cluster TLS configuration, meaning that if you add nodes
to your cluster, communication between them will not be secure.
First, make sure that you have Garage installed in your command line environment.
We will explain how to launch Garage in a Docker container, however we still
recommend that you install the `garage` CLI on your host system in order to control
the daemon.
## Writing a first configuration file
This first configuration file should allow you to get started easily with the simplest
possible Garage deployment:
```toml
metadata_dir = "/tmp/meta"
data_dir = "/tmp/data"
replication_mode = "none"
rpc_bind_addr = "[::]:3901"
bootstrap_peers = []
[s3_api]
s3_region = "garage"
api_bind_addr = "[::]:3900"
[s3_web]
bind_addr = "[::]:3902"
root_domain = ".web.garage"
index = "index.html"
```
Save your configuration file as `garage.toml`.
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 HDD if you want
your data to be persisted properly.
## Launching the Garage server
#### Option 1: directly (without Docker)
Use the following command to launch the Garage server with our configuration file:
```
garage server -c garage.toml
```
By default, Garage displays almost no output. You can tune Garage's verbosity as follows
(from less verbose to more verbose):
```
RUST_LOG=garage=info garage server -c garage.toml
RUST_LOG=garage=debug garage server -c garage.toml
RUST_LOG=garage=trace garage server -c garage.toml
```
Log level `info` is recommended for most use cases.
Log level `debug` can help you check why your S3 API calls are not working.
#### Option 2: in a Docker container
Use the following command to start Garage in a docker container:
```
docker run -d \
-p 3901:3901 -p 3902:3902 -p 3900:3900 \
-v $PWD/garage.toml:/garage/garage.toml \
lxpz/garage_amd64:v0.3.0
```
To tune Garage's verbosity level, set the `RUST_LOG` environment variable in the configuration
at launch time. For instance:
```
docker run -d \
-p 3901:3901 -p 3902:3902 -p 3900:3900 \
-v $PWD/garage.toml:/garage/garage.toml \
-e RUST_LOG=garage=info \
lxpz/garage_amd64:v0.3.0
```
## Checking that Garage runs correctly
The `garage` utility is also used as a CLI tool to configure your Garage deployment.
It tries to connect to a Garage server through the RPC protocol, by default looking
for a Garage server at `localhost:3901`.
Since our deployment already binds to port 3901, the following command should be sufficient
to show Garage's status, provided that you installed the `garage` binary on your host system:
```
garage status
```
Move on to [controlling the Garage daemon](04_control.md) to learn more about how to
use the Garage CLI to control your cluster.
Move on to [configuring your cluster](05_cluster.md) in order to configure
your single-node deployment for actual use!

Upgrading between Garage versions should be supported transparently,
but please check the relase notes before doing so!
To upgrade, simply stop and remove this container and

### For systemd/raw binary users
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'

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.

# Control the daemon
The `garage` binary has two purposes:
- it acts as a daemon when launched with `garage server ...`
- it acts as a control tool for the daemon when launched with any other command
In this section, we will see how to use the `garage` binary as a control tool for the daemon we just started.
You first need to get a shell having access to this binary, which depends of your configuration:
- with `docker`, run `sudo docker exec -ti garaged bash`, you will now have a shell
where the Garage binary is available as `/garage/garage`
- with `systemd`, simply run `/usr/local/bin/garage` if you followed previous instructions
*You can also install the binary on your machine to remotely control the cluster.*
## Talk to the daemon and create an alias
`garage` requires 4 options to talk with the daemon:
```
--ca-cert <ca-cert>
--client-cert <client-cert>
--client-key <client-key>
-h, --rpc-host <rpc-host>
```
The 3 first ones are certificates and keys needed by TLS, the last one is simply the address of garage's RPC endpoint.
Because we configure garage directly from the server, we do not need to set `--rpc-host`.
To avoid typing the 3 first options each time we want to run a command, we will create an alias.
### test deployment
If you have simply deployed Garage on your local machine, without TLS, you can invoke
`garage` directly without any of these parameters and without making a `garagectl` alias
(replace mentions of `garagectl` in the next sections by `garage`).
### `docker` alias
```bash
alias garagectl='/garage/garage \
--ca-cert /etc/garage/pki/garage-ca.crt \
--client-cert /etc/garage/pki/garage.crt \
--client-key /etc/garage/pki/garage.key'
```
### raw binary alias
```bash
alias garagectl='/usr/local/bin/garage \
--ca-cert /etc/garage/pki/garage-ca.crt \
--client-cert /etc/garage/pki/garage.crt \
--client-key /etc/garage/pki/garage.key'
```
Of course, if your deployment does not match exactly one of this alias, feel free to adapt it to your needs!
## Test the alias
You can test your alias by running a simple command such as:
```
garagectl status
```
You should get something like that as result:
```
Healthy nodes:
2a638ed6c775b69a… 37f0ba978d27 [::ffff:172.20.0.101]:3901 UNCONFIGURED/REMOVED
68143d720f20c89d… 9795a2f7abb5 [::ffff:172.20.0.103]:3901 UNCONFIGURED/REMOVED
8781c50c410a41b3… 758338dde686 [::ffff:172.20.0.102]:3901 UNCONFIGURED/REMOVED
```
...which means that you are ready to [configure your cluster](05_cluster.md)!

# Configure a cluster
*We use a command named `garagectl` which is in fact an alias you must define as explained in the [Control the daemon](./daemon.md) section.*
In this section, we will inform garage of the disk space available on each node of the cluster
as well as the site (think datacenter) of each machine.
## Test cluster
As this part is not relevant for a test cluster, you can use this three-liner to create a basic topology:
```bash
garagectl status | grep UNCONFIGURED | grep -Po '^[0-9a-f]+' | while read id; do
garagectl node configure -z dc1 -c 1 $id
done
```
## Real-world cluster
For our example, we will suppose we have the following infrastructure (Capacity, Identifier and Datacenter are specific values to garage described in the following):
| Location | Name | Disk Space | `Capacity` | `Identifier` | `Zone` |
|----------|---------|------------|------------|--------------|--------------|
| Paris | Mercury | 1 To | `2` | `8781c5` | `par1` |
| Paris | Venus | 2 To | `4` | `2a638e` | `par1` |
| London | Earth | 2 To | `4` | `68143d` | `lon1` |
| Brussels | Mars | 1.5 To | `3` | `212f75` | `bru1` |
### Identifier
After its first launch, garage generates a random and unique identifier for each nodes, such as:
```
8781c50c410a41b363167e9d49cc468b6b9e4449b6577b64f15a249a149bdcbc
```
Often a shorter form can be used, containing only the beginning of the identifier, like `8781c5`,
which identifies the server "Mercury" located in "Paris" according to our previous table.
The most simple way to match an identifier to a node is to run:
```
garagectl status
```
It will display the IP address associated with each node; from the IP address you will be able to recognize the node.
### Zones
Zones are simply a user-chosen identifier that identify a group of server that are grouped together logically.
It is up to the system administrator deploying garage to identify what does "grouped together" means.
In most cases, a zone will correspond to a geographical location (i.e. a datacenter).
Behind the scene, Garage will use zone definition to try to store the same data on different zones,
in order to provide high availability despite failure of a zone.
### Capacity
Garage reasons on an arbitrary metric about disk storage that is named the *capacity* of a node.
The capacity configured in Garage must be proportional to the disk space dedicated to the node.
Additionaly, the capacity values used in Garage should be as small as possible, with
1 ideally representing the size of your smallest server.
Here we chose that 1 unit of capacity = 0.5 To, so that we can express servers of size
1 To and 2 To, as wel as the intermediate size 1.5 To.
Note that the amount of data stored by Garage on each server may not be strictly proportional to
its capacity value, as Garage will priorize having 3 copies of data in different zones,
even if this means that capacities will not be strictly respected. For example in our above examples,
nodes Earth and Mars will always store a copy of everything each, and the third copy will
have 66% chance of being stored by Venus and 33% chance of being stored by Mercury.
### Inject the topology
Given the information above, we will configure our cluster as follow:
```
garagectl node configure -z par1 -c 2 -t mercury 8781c5
garagectl node configure -z par1 -c 4 -t venus 2a638e
garagectl node configure -z lon1 -c 4 -t earth 68143d
garagectl node configure -z bru1 -c 3 -t mars 212f75
```

# Create buckets and keys
*We use a command named `garagectl` which is in fact an alias you must define as explained in the [Control the daemon](./daemon.md) section.*
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:
```
garagectl help
garagectl bucket allow --help
```
## Create a bucket
Fine, now let's create a bucket (we imagine that you want to deploy nextcloud):
```
garagectl bucket create nextcloud-bucket
```
Check that everything went well:
```
garagectl bucket list
garagectl bucket info nextcloud-bucket
```
## Create an API key
Now we will generate an API key to access this bucket.
Note that API keys are independent of buckets: one key can access multiple buckets, multiple keys can access one bucket.
Now, let's start by creating a key only for our PHP application:
```
garagectl key new --name nextcloud-app-key
```
You will have the following output (this one is fake, `key_id` and `secret_key` were generated with the openssl CLI tool):
```
Key name: nextcloud-app-key
Key ID: GK3515373e4c851ebaad366558
Secret key: 7d37d093435a41f2aab8f13c19ba067d9776c90215f56614adad6ece597dbb34
Authorized buckets:
```
Check that everything works as intended:
```
garagectl key list
garagectl 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!
```
garagectl bucket allow \
--read \
--write
nextcloud-bucket \
--key nextcloud-app-key
```
You can check at any times allowed keys on your bucket with:
```
garagectl bucket info nextcloud-bucket
```

# Handle files
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 in the [previous section](bucket.md).
You also need to set the endpoint: it must match the IP address of one of the node of the cluster and the API port (3900 by default).
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://172.20.0.101:3900 \
<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).
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
```

# 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 real-world deployment](../cookbook/real_world.md).
Note that this kind of deployment should not be used in production, as it provides
no redundancy for your data!
We will also skip intra-cluster TLS configuration, meaning that if you add nodes
to your cluster, communication between them will not be secure.
## Get a binary
Download the latest Garage binary from the release pages on our repository:
<https://git.deuxfleurs.fr/Deuxfleurs/garage/releases>
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,
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:
```toml
metadata_dir = "/tmp/meta"
data_dir = "/tmp/data"
replication_mode = "none"
rpc_bind_addr = "[::]:3901"
bootstrap_peers = []
[s3_api]
s3_region = "garage"
api_bind_addr = "[::]:3900"
[s3_web]
bind_addr = "[::]:3902"
root_domain = ".web.garage"
index = "index.html"
```
Save your configuration file as `garage.toml`.
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 -c garage.toml
```
By default, Garage displays almost no output. You can tune Garage's verbosity as follows
(from less verbose to more verbose):
```
RUST_LOG=garage=info garage server -c garage.toml
RUST_LOG=garage=debug garage server -c garage.toml
RUST_LOG=garage=trace garage server -c garage.toml
```
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 tries to connect to a Garage server through the RPC protocol, by default looking
for a Garage server at `localhost:3901`.
Since our deployment already binds to port 3901, the following command should be sufficient
to show Garage's status:
```
garage status
```
This should show something like this:
```
Healthy nodes:
2a638ed6c775b69a… linuxbox 127.0.0.1:3901 UNCONFIGURED/REMOVED
```
## Configuring your Garage node
Configuring the nodes in 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 node configure -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 node configure -z dc1 -c 1 2a63`.
## 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 ["configuring clients"](../cookbook/clients.md) to learn how to configure
these clients to interact with a Garage server.
