## Usage

### Quick start

```yaml
name: ci

on:
push:

jobs:
docker:
runs-on: ubuntu-latest
steps:
-
name: Set up Docker
uses: crazy-max/ghaction-setup-docker@v3
```

### Daemon configuration

You can [configure the Docker daemon](https://docs.docker.com/engine/reference/commandline/dockerd/#daemon-configuration-file)
using the `daemon-config` input. In the following example, we configure the
Docker daemon to enable debug and the [containerd image store](https://docs.docker.com/storage/containerd/)
feature:

```yaml
name: ci

on:
push:

jobs:
docker:
runs-on: ubuntu-latest
steps:
-
name: Set up Docker
uses: crazy-max/ghaction-setup-docker@v3
with:
daemon-config: |
{
"debug": true,
"features": {
"containerd-snapshotter": true
}
}
```

### Define custom `limactl start` arguments (macOS)

You can define custom [`limactl start` arguments](https://lima-vm.io/docs/reference/limactl_start/)
using the `LIMA_START_ARGS` environment variable to customize the VM:

```yaml
name: ci

on:
push:

jobs:
docker:
runs-on: macos-latest
steps:
-
name: Set up Docker
uses: crazy-max/ghaction-setup-docker@v3
env:
LIMA_START_ARGS: --cpus 4 --memory 8
```
