2 - Workflow Syntax

In this lab you will update the workflow syntax.

Duration: 5-10 minutes

References:

• Workflow syntax for GitHub Actions
• Using jobs in a workflow
• Environment variables

2.1 Add new jobs with dependencies

1. Open the workflow file job-dependencies.yml
2. Edit the file and copy the following YAML content at the end of the file:

  build:
    runs-on: windows-latest
    steps:
      - run: echo "This job will be run in parallel with the initial job."
  test:
    runs-on: ubuntu-latest
    needs: build
    steps:
      - run: echo "This job will be run after the build job."
  ring01:
    runs-on: ubuntu-latest
    needs: test
    steps:
      - run: echo "This job will be run after the test job."
  ring02:
    runs-on: macos-latest
    needs: test
    steps:
      - run: echo "This job will be run after the test job."
  ring03:
    runs-on: ubuntu-latest
    needs: test
    steps:
      - run: echo "This job will be run after the test job."
  ring04:
    runs-on: ubuntu-latest
    needs: [ring01,ring02,ring03]
    steps:
      - run: echo "This job will be run after the ring01,ring02,ring03 jobs."
  prod:
    runs-on: ubuntu-latest
    needs: [ring04]
    steps:
      - run: echo "This job will be run after the ring04 job."

3. Commit the changes into the main branch
4. Go to Actions and manually trigger the workflow by clicking on Run Workflow button
5. See the details of your running workflow

2.2 Create a matrix build

1. Using the same file as step 2.1, copy the following YAML content and replace the build job

  build:
    runs-on: ubuntu-latest  
    strategy:
      matrix:
        configuration: [debug, release]
    steps:
    - run: echo "This job builds the cofiguration ${{ matrix.configuration }}."

2. Update the workflow to run on push events

on:
  workflow_dispatch:
  push:
    branches:
      - main

3. Commit the changes into the main branch
4. Go to Actions and see the details of your running workflow
