GitHub Actions

The following code sample demonstrates how to integrate Dagger with GitHub Actions.

.github/workflows/dagger.yml

name: dagger
on:
  push:
    branches: [main]

jobs:
  build:
    name: build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4
      -
        name: Call Dagger Function
        uses: dagger/dagger-for-github@v5
        with:
          version: "latest"
          verb: call
          # assumes a Go project
          # modify to use different function(s) as needed
          module: github.com/kpenfound/dagger-modules/golang@v0.1.5
          args: build --project=. --args=.
          # assumes the Dagger Cloud token is in
          # a repository secret named DAGGER_CLOUD_TOKEN
          # set via the GitHub UI/CLI
          cloud-token: ${{ secrets.DAGGER_CLOUD_TOKEN }}

The following code sample demonstrates how to use Dagger in a GitHub Action to publish a container image to GitHub Container Registry.

.github/workflows/dagger.yml

name: dagger
on:
  push:
    branches: [main]

jobs:
  build-publish:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      packages: write
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Call Dagger Function to build and publish to ghcr.io
        uses: dagger/dagger-for-github@v5
        with:
          version: "latest"
          verb: call
          # modify to use different function(s) as needed
          module: github.com/daggerverse/dagger-ghcr-demo@v0.1.5
          args: build-and-push --registry=$DOCKER_REGISTRY --image-name=$DOCKER_IMAGE_NAME --username=$DOCKER_USERNAME --password=env:DOCKER_PASSWORD --build-context=github.com/daggerverse/dagger-ghcr-demo
          # assumes the Dagger Cloud token is in
          # a repository secret named DAGGER_CLOUD_TOKEN
          # set via the GitHub UI/CLI
          cloud-token: ${{ secrets.DAGGER_CLOUD_TOKEN }}
        env:
          DOCKER_REGISTRY: ghcr.io
          DOCKER_IMAGE_NAME: ${{ github.repository }}
          DOCKER_USERNAME: ${{ github.actor }}
          # assumes the container registry password is in
          # a repository secret named REGISTRY_PASSWORD
          # set via the GitHub UI/CL
          DOCKER_PASSWORD: ${{ secrets.REGISTRY_PASSWORD }}
