5 - Custom actions

In this lab you will create and use custom actions.

Duration: 15-20 minutes

References:

5.1 Use the github-script action to apply a label to an issue

  1. Open the workflow file github-script.yml
  2. Edit the file and copy the following YAML content at the end of the file:
  apply-label:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/github-script@v6
        with:
          script: |
            github.rest.issues.addLabels({
              issue_number: context.issue.number,
              owner: context.repo.owner,
              repo: context.repo.repo,
              labels: ['Training']
            })
  1. Commit the changes into the main branch
  2. Open a new issue or edit an exiting one to trigger the workflow
  3. Go to Actions and see the details of your running workflow
  4. After the workflow completes, a new label should be applied to your issue

5.2 Use a composite action

  1. Open the composite action file /.github/actions/hello-world-composite-action/action.yml
  2. Edit the file and copy the following YAML content at the end of the file:
    - name: Hello world
      uses: actions/hello-world-javascript-action@v1
      with:
        who-to-greet: "${{ inputs.who-to-greet }}"
      id: hello
    - name: Echo the greeting's time
      run: echo 'The time was ${{ steps.hello.outputs.time }}.'
      shell: bash
  1. Commit the changes into a new feature/lab05 branch
  2. Open the workflow file hello-world-composite.yml
  3. Edit the file and copy the following YAML content at the end of the file:
  hello_world_job2:
    runs-on: ubuntu-latest
    name: A job2 to say hello
    steps:
      - uses: actions/checkout@v2
      - id: hello-world
        uses: ./.github/actions/hello-world-composite-action
        with:
          who-to-greet: 'Mona the Octocat from composite action'
      - run: echo random-number from composite action ${{ steps.hello-world.outputs.random-number }}
        shell: bash
  1. Update the workflow to run on pull_request events
on:
  pull_request:
     branches: [main]
  workflow_dispatch:
  1. Commit the changes into the same feature/lab05 branch
  2. Open a new pull request
  3. Go to Actions and see the details of your running workflow
  4. Complete the pull request and delete the source branch

5.3 Custom JS and Docker actions

  1. Study the implementation of the custom action from the folder: /.github/actions/
  2. Open the workflow file use-custom-actions.yml
  3. Edit the file and copy the following YAML content to update the issue title:
         issue-title: "A joke for you from custom actions workflow"
  1. Commit the changes into the main branch
  2. Go to Actions and manually trigger the workflow by clicking on Run Workflow button
  3. See the details of your running workflow

5.4 (Optional) Create a JavaScript action

  1. Follow the guide to create a JavaScript action
  2. Use your action in a workflow
      - name: Hello world action step
        id: hello
