Summary - Actions workflow

Combine the workflow parts to build a robust CI.

Modern CI/CD workflow architecture

A robust GitHub Actions pipeline combines speed, security, and multi-environment support. matrix tests code across all target platforms and versions, while actions/cache preserves dependencies to slash build durations. Credentials are encrypted and safely injected using secrets.

jobs:
  test:
    strategy:
      matrix:
        node: [18, 20]
    steps:
      - uses: actions/cache@v4
      - env:
          KEY: ${{ secrets.API_KEY }}

Combining these three pillars yields an enterprise-grade CI/CD pipeline.

Exercise Complete deploy step with secret

Add the name: Dagitim step with KEY: ${{ secrets.DEPLOY_KEY }} under env: and run: echo "Dagitim tamam".

Show example solution

cat << 'EOF' > .github/workflows/ci.yml
jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node: [18, 20]
    steps:
      - uses: actions/checkout@v4
      - name: Dagitim
        env:
          KEY: ${{ secrets.DEPLOY_KEY }}
        run: echo "Dagitim tamam"

Test yourself

Which trio of features is used to build a fast, secure, multi-platform deployment pipeline?
- matrix, actions/cache, and secrets
- git status, git diff, and git add
- git rebase, git merge, and git reset
- git stash, git pop, and git clean
Show answer

matrix, actions/cache, and secrets — Matrix enables multi-version testing, cache provides speed, and secrets ensures secure credential management in modern CI pipelines.

Keep other matrix jobs on failure

    strategy:
      ____: false

Show answer

    strategy:
      fail-fast: false
