Save your configuration file as `garage.toml`.
The `rpc_secret` value provided above is just an example. It will work, but in
order to secure your cluster you will need to use another one. You can generate
such a value with `openssl rand -hex 32`.
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

Use the following command to launch the Garage server with our configuration file:

## 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`.
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`.
Since our deployment already binds to port 3901, the following command should be sufficient
to show Garage's status:
