{% data reusables.repositories.about-github-actions %} {% data reusables.repositories.actions-ci-cd %} For more information, see "About {% data variables.product.prodname_actions %}."

You can extend the CI and CD capabilities of your repository by publishing or installing packages as part of your workflow.

Authenticating to package registries on {% data variables.product.prodname_dotcom %}

{% if currentVersion == "free-pro-team@latest" %}If you want your workflow to authenticate to {% data variables.product.prodname_registry %} to access a package registry other than the {% data variables.product.prodname_container_registry %} on {% data variables.product.product_name %}, then{% else %}To authenticate to package registries on {% data variables.product.product_name %},{% endif %} we recommend using the GITHUB_TOKEN that {% data variables.product.product_name %} automatically creates for your repository when you enable {% data variables.product.prodname_actions %} instead of a personal access token for authentication. The GITHUB_TOKEN has read:packages and write:packages scopes to the current repository. For forks, the token also has the read:packages scope for the parent repository.

You can reference the GITHUB_TOKEN in your workflow file using the {% raw %}{{secrets.GITHUB_TOKEN}}{% endraw %} context. For more information, see "Authenticating with the GITHUB_TOKEN."

Publishing a package using an action

You can use {% data variables.product.prodname_actions %} to automatically publish packages as part of your continuous integration (CI) flow. This approach to continuous deployment (CD) allows you to automate the creation of new package versions, if the code meets your quality standards. For example, you could create a workflow that runs CI tests every time a developer pushes code to a particular branch. If the tests pass, the workflow can publish a new package version to {% data variables.product.prodname_registry %}.

{% data reusables.package_registry.actions-configuration %}

The following example demonstrates how you can use {% data variables.product.prodname_actions %} to build and test your app, and then automatically create a Docker image and publish it to {% data variables.product.prodname_registry %}:

• Create a new workflow file in your repository (such as .github/workflows/deploy-image.yml), and add the following YAML: {% raw %}

  name: Create and publish a package
  on:
    push:
      branches: ['release']
  jobs:
    run-npm-build:
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v2
        - name: npm install and build webpack
          run: |
            npm install
            npm run build
        - uses: actions/upload-artifact@main
          with:
            name: webpack artifacts
            path: public/
  
    run-npm-test:
      runs-on: ubuntu-latest
      needs: run-npm-build
      strategy:
        matrix:
          os: [ubuntu-latest]
          node-version: [12.x, 14.x]
      steps:
        - uses: actions/checkout@v2
        - name: Use Node.js ${{ matrix.node-version }}
          uses: actions/setup-node@v1
          with:
            node-version: ${{ matrix.node-version }}
        - uses: actions/download-artifact@main
          with:
            name: webpack artifacts
            path: public
        - name: npm install, and test
          run: |
            npm install
            npm test
          env:
            CI: true
  
    build-and-push-image:
      runs-on: ubuntu-latest
      needs: run-npm-test
      steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Build container image
        uses: docker/build-push-action@v1
        with:
          username: ${{ github.actor }}
          password: ${{ secrets.GITHUB_TOKEN }}
          registry: docker.pkg.github.com
          repository: ${{ github.repository }}/octo-image
          tag_with_sha: true
          tag_with_ref: true
  

  {% endraw %}

  The relevant settings are explained in the following table:

  {% raw %} on: push: branches: ['release'] {% endraw %}	Configures the Create and publish a package workflow to run every time a change is pushed to the branch called release.
  {% raw %} run-npm-build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - name: npm install and build webpack run: | npm install npm run build - uses: actions/upload-artifact@main with: name: webpack artifacts path: public/ {% endraw %}	This job installs NPM and uses it to build the app.
  {% raw %} run-npm-test: runs-on: ubuntu-latest needs: run-npm-build strategy: matrix: os: [ubuntu-latest] node-version: [14.x] steps: - uses: actions/checkout@v2 - name: Use Node.js ${{ matrix.node-version }} uses: actions/setup-node@v1 with: node-version: ${{ matrix.node-version }} - uses: actions/download-artifact@main with: name: webpack artifacts path: public - name: npm install, and test run: | npm install npm test env: CI: true {% endraw %}	This job uses npm test to test the code. The needs: run-npm-build command makes this job dependent on the run-npm-build job.
  {% raw %} - name: Build container image {% endraw %}	Creates a new step called Build container image. This step runs as part of the build-and-push-image job. The needs: run-npm-test command makes this job dependent on the run-npm-test job.
  {% raw %} uses: docker/build-push-action@v1 {% endraw %}	Uses the Docker build-push-action action to build the image, based on your repository's Dockerfile. If the build succeeds, it pushes the image to {% data variables.product.prodname_registry %}.
  {% raw %} with: {% endraw %}	Sends the required parameters to the build-push-action action. This are defined in the subsequent lines.
  {% raw %} username: ${{ github.actor }} {% endraw %}	Defines the user account that will publish the packages. Once published, the packages are owned by the account defined here.
  {% raw %} password: ${{ secrets.GITHUB_TOKEN }} {% endraw %}	Defines the password that is used to access {% data variables.product.prodname_registry %}.
  {% raw %} registry: docker.pkg.github.com {% endraw %}	Defines the registry that will host the resulting packages. This example uses {% data variables.product.prodname_registry %}.
  {% raw %} repository: ${{ github.repository }}/octo-image {% endraw %}	Defines which repository will host the resulting package, and sets the name of the published package. Replace octo-image with the name you want for your package.
  {% raw %} tag_with_sha: true {% endraw %}	Tags the published package with the first seven characters of the commit's SHA. For example, sha-2f2d842.
  {% raw %} tag_with_ref: true {% endraw %}	Tags the published package with the git ref. This can be the name of the branch used to create the package.

  • This new workflow will run automatically every time you push a change to the repository. You can view the progress in the Actions tab.
  • A few minutes after the workflow has completed, the new package will visible in your repository. To find your available packages, see "Viewing a repository's packages."

  Installing a package using an action

  You can install packages as part of your CI flow using {% data variables.product.prodname_actions %}. For example, you could configure a workflow so that anytime a developer pushes code to a pull request, the workflow resolves dependencies by downloading and installing packages hosted by {% data variables.product.prodname_registry %}. Then, the workflow can run CI tests that require the dependencies.

  Installing packages hosted by {% data variables.product.prodname_registry %} through {% data variables.product.prodname_actions %} requires minimal configuration or additional authentication when you use GITHUB_TOKEN.{% if currentVersion == "free-pro-team@latest" %} Data transfer is also free when an action installs a package. For more information, see "About billing for {% data variables.product.prodname_registry %}."{% endif %}

  {% if currentVersion == "free-pro-team@latest" %} GITHUB_TOKEN cannot install packages from any private repository besides the repository where the action runs. You cannot currently use GITHUB_TOKEN to authenticate to {% data variables.product.prodname_github_container_registry %}. {% endif %}
