## About
|
|
|
|
GitHub Action to set up (download and install) [Docker CE](https://docs.docker.com/engine/).
|
|
Works on Linux, macOS and Windows.
|
|
|
|
> [!NOTE]
|
|
> This action is useful if you want to pin against a specific Docker version or
|
|
> set up a custom daemon configuration or if Docker is not available on your
|
|
> runner. If you're using [GitHub-hosted runners](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources)
|
|
> on Linux or Windows, Docker is already up and running, so it might not be
|
|
> necessary to use this action.
|
|
|
|
> [!WARNING]
|
|
> Does not work on macOS runners with ARM architecture (no nested virtualization):

## Usage
|
|
|
|
### Quick start
|
|
|
|
```yaml
|
|
name: ci
|
|
|
|
on:
|
|
push:
|
|
|
|
jobs:
|
|
docker:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
-
|
|
name: Set up Docker
|
|
uses: docker/setup-docker-action@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: docker/setup-docker-action@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: docker/setup-docker-action@v3
|
|
env:
|
|
LIMA_START_ARGS: --cpus 4 --memory 8
|
|
```
|
|
|
|
