# Managing Garage

The garage project provides the network storage component for
Isle. If you're reading this document then you would likely benefit
greatly from reading the [garage documentation][garage] on their website. It's
extremely well written and concise.

Note that the `isle daemon` process will handle all setup steps described
in that documentation, but it's still good to have an understanding of how
garage works and what it can do.

## Garage Runtime Note

There is an important thing to note regarding how isle runs garage. As
described in the [Contributing Storage](contributing-storage.md) document, a
single `isle daemon` process can be configured to provide any number of
storage allocations.

For each allocation which is configured, `isle daemon` will configure and
run a separate `garage server` instance as a sub-process. Each garage will use
the host's name as its zone in the garage cluster layout, which means that the
cluster will prefer to not replicate the same data within the same host, but may
do so if necessary.

## Garage CLI

Every `isle` binary contains a full `garage` binary embedded into it.
This binary can be accessed directly like so:

```
sudo isle garage cli <subcmd> <args>
```

Before handing off execution to the `garage` binary, the `isle` process
will automatically set up the RPC host and secret environment variables.

If the host which is running the command has more than one allocation
configured, then the `garage server` process for the first allocation will be
connected to by this invocation of `garage`. If no allocations are configured,
then the `garage server` process of some other host in the network will be
connected to.

## Examples

To display the current layout of the garage cluster:

```
sudo isle garage cli layout show
```

**(DO NOT CHANGE THE CLUSTER LAYOUT UNLESS YOU KNOW WHAT YOU'RE DOING!)**

To create a new bucket:

```
sudo isle garage cli bucket create new-bucket
```

To list existing buckets:

```
sudo isle garage cli bucket list
```
