  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

env:
  NODE_VERSION: '20'
  REGISTRY: ghcr.io
  IMAGE_NAME: ${{ github.repository }}

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node: [18, 20, 22]
    steps:
      - uses: actions/checkout@v4

      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: ${{ matrix.node }}
          cache: 'npm'

      - name: Install dependencies
        run: npm ci

                script {
                    docker.build("${DOCKER_REGISTRY}/${IMAGE_NAME}:${env.BUILD_NUMBER}")
                }
            }
        }

        stage('Push') {
            when {
                branch 'main'
            }
            steps {
                script {
                    docker.withRegistry("https://${DOCKER_REGISTRY}", 'docker-credentials') {
                        docker.image("${DOCKER_REGISTRY}/${IMAGE_NAME}:${env.BUILD_NUMBER}").push()
                        docker.image("${DOCKER_REGISTRY}/${IMAGE_NAME}:${env.BUILD_NUMBER}").push('latest')
                    }
                }
            }
        }

        stage('Deploy') {
            when {
                branch 'main'
            }
            steps {
                echo "Deploying build ${env.BUILD_NUMBER}"

                body: "Check console output at ${env.BUILD_URL}",
                recipientProviders: [developers(), requestor()]
            )
        }
    }
}

            deploy:
              steps:
                - script: echo "Deploying to production"

5. Pipeline Optimization

Optimization strategies:

# Caching strategies
- uses: actions/cache@v4
  with:
    path: |
      ~/.npm
      node_modules
    key: ${{ runner.os }}-node-${{ hashFiles('**/package-lock.json') }}
    restore-keys: |
      ${{ runner.os }}-node-

# Parallelization
jobs:
  test:
    strategy:
      fail-fast: false
      matrix:
        shard: [1, 2, 3, 4]
    steps:
      - run: npm test -- --shard=${{ matrix.shard }}/4

# Conditional execution
- name: Deploy
  if: github.event_name == 'push' && github.ref == 'refs/heads/main'

6. Security Scanning

Integrate security scanning:

- name: Run Trivy vulnerability scanner
  uses: aquasecurity/trivy-action@master
  with:
    image-ref: '${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ github.sha }}'
    format: 'sarif'
    output: 'trivy-results.sarif'

- name: Upload Trivy scan results
  uses: github/codeql-action/upload-sarif@v3
  with:
    sarif_file: 'trivy-results.sarif'

Best Practices

Pipeline Design

1. Fast feedback - Run quick tests first
2. Fail fast - Stop on first failure when appropriate
3. Idempotent - Pipelines should be rerunnable
4. Parallelization - Use matrix builds and parallel jobs
5. Caching - Cache dependencies and build artifacts

Security

1. Least privilege - Minimal permissions for tokens
2. Secret management - Use platform secret stores
3. Dependency scanning - Scan for vulnerabilities
4. Image scanning - Scan container images
5. OIDC - Prefer OIDC over long-lived tokens

Optimization

1. Incremental builds - Only rebuild what changed
2. Docker layer caching - Optimize Dockerfile for caching
3. Artifact reuse - Share artifacts between jobs
4. Resource sizing - Right-size runners/agents

Process Integration

This skill integrates with the following processes:

• cicd-pipeline-setup.js - Initial pipeline configuration
• pipeline-optimization.js - Performance tuning
• security-scanning.js - Security integration

Output Format

When executing operations, provide structured output:

{
  "operation": "generate-pipeline",
  "platform": "github-actions",
  "status": "success",
  "workflow": {
    "name": "CI/CD Pipeline",
    "jobs": 3,
    "stages": ["test", "build", "deploy"]
  },
  "optimizations": [
    "Added dependency caching",
    "Enabled parallel test execution",
    "Configured Docker layer caching"
  ],
  "artifacts": [".github/workflows/ci.yml"]
}

Constraints

• Validate workflow syntax before committing
• Test in non-production environments first
• Document all environment variables and secrets
• Include timeout configurations
• Add failure notifications
