Usage

Quick start

name: ci

on:
  push:

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      -
        name: Set up Docker
        uses: step-security/ghaction-setup-docker@v3

Daemon configuration

You can configure the Docker daemon using the daemon-config input. In the following example, we configure the Docker daemon to enable debug and the containerd image store feature:

name: ci

on:
  push:

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      -
        name: Set up Docker
        uses: step-security/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 using the LIMA_START_ARGS environment variable to customize the VM:

name: ci

on:
  push:

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