GitHub Actions Templates

Production-ready GitHub Actions workflow patterns for testing, building, and deploying applications.

Purpose

Create efficient, secure GitHub Actions workflows for continuous integration and deployment across various tech stacks.

When to Use

• Automate testing and deployment
• Build Docker images and push to registries
• Deploy to Kubernetes clusters
• Run security scans
• Implement matrix builds for multiple environments

Common Workflow Patterns

Pattern 1: Test Workflow

name: Test

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

jobs:
  test:
    runs-on: ubuntu-latest

    strategy:
      matrix:
        node-version: [18.x, 20.x]

    steps:
      - uses: actions/checkout@v4

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

      - name: Install dependencies
        run: npm ci

      - name: Run linter
        run: npm run lint

      - name: Run tests
        run: npm test

      - name: Upload coverage
        uses: codecov/codecov-action@v3
        with:
          files: ./coverage/lcov.info

Reference: See assets/test-workflow.yml

Pattern 2: Build and Push Docker Image

name: Build and Push

on:
  push:
    branches: [main]
    tags: ["v*"]

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

jobs:
  build:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      packages: write

    steps:
      - uses: actions/checkout@v4

      - name: Log in to Container Registry
        uses: docker/login-action@v3
        with:
          registry: ${{ env.REGISTRY }}
          username: ${{ github.actor }}
          password: ${{ secrets.GITHUB_TOKEN }}

      - name: Extract metadata
        id: 
         
        
               
           
          
         
        
           
           
             
             
           
           

Reference: See assets/deploy-workflow.yml

Pattern 3: Deploy to Kubernetes

name: Deploy to Kubernetes

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - name: Configure AWS credentials
        uses: aws-actions/configure-aws-credentials@v4
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: us-west-2

      - name: Update kubeconfig
        run: |
          aws eks update-kubeconfig --name production-cluster --region us-west-2

      - name: Deploy to Kubernetes
        run: |
          kubectl apply -f k8s/
          kubectl rollout status deployment/my-app -n production
          kubectl get services -n production

      - name: Verify deployment
        run: 

Pattern 4: Matrix Build

name: Matrix Build

on: [push, pull_request]

jobs:
  build:
    runs-on: ${{ matrix.os }}

    strategy:
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
        python-version: ["3.9", "3.10", "3.11", "3.12"]

    steps:
      - uses: actions/checkout@v4

      - name: Set up Python
        uses: actions/setup-python@v5
        with:
          python-version: ${{ matrix.python-version }}

      - name: Install dependencies
        run: |
          python -m pip install --upgrade pip
          pip install -r requirements.txt

      - name: Run tests
        run: pytest

Reference: See assets/matrix-build.yml

Workflow Best Practices

1. Use specific action versions (@v4, not @latest)
2. Cache dependencies to speed up builds
3. Use secrets for sensitive data
4. Implement status checks on PRs
5. Use matrix builds for multi-version testing
6. Set appropriate permissions
7. Use reusable workflows for common patterns
8. Implement approval gates for production
9. Add notification steps for failures
10. Use self-hosted runners for sensitive workloads

Reusable Workflows

# .github/workflows/reusable-test.yml
name: Reusable Test Workflow

on:
  workflow_call:
    inputs:
      node-version:
        required: true
        type: string
    secrets:
      NPM_TOKEN:
        required: true

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ inputs.node-version }}
      - run: npm ci
      - run: npm test

Use reusable workflow:

jobs:
  call-test:
    uses: ./.github/workflows/reusable-test.yml
    with:
      node-version: "20.x"
    secrets:
      NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

Security Scanning

name: Security Scan

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  security:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - name: Run Trivy vulnerability scanner
        uses: aquasecurity/trivy-action@master
        with:
          scan-type: "fs"
          scan-ref: "."
          format: "sarif"
          output: "trivy-results.sarif"

      - name: Upload Trivy results to GitHub Security
        uses: github/codeql-action/upload-sarif@v2
        with:
          sarif_file: "trivy-results.sarif"

      - name: Run Snyk Security Scan
        uses: 
        
             

Deployment with Approvals

name: Deploy to Production

on:
  push:
    tags: ["v*"]

jobs:
  deploy:
    runs-on: ubuntu-latest
    environment:
      name: production
      url: https://app.example.com

    steps:
      - uses: actions/checkout@v4

      - name: Deploy application
        run: |
          echo "Deploying to production..."
          # Deployment commands here

      - name: Notify Slack
        if: success()
        uses: slackapi/slack-github-action@v1
        with:
          webhook-url: ${{ secrets.SLACK_WEBHOOK }}
          payload: |
            {
              "text": "Deployment to production completed successfully!"
            }
