GitHub Actions Guide Part 3: Real-world Applications and Troubleshooting

Welcome to the third and final part of our GitHub Actions guide! In Part 1 we introduced the fundamentals of GitHub Actions, and in Part 2 we explored building advanced workflows. Now, let’s dive into real-world applications, practical examples, and techniques for troubleshooting common issues.

Real-world CI/CD Pipelines

Let’s explore how GitHub Actions enables continuous integration and continuous deployment for various application types.

Building and Testing a Node.js Application

Here’s a practical workflow for a Node.js application that:

  1. Installs dependencies
  2. Runs linting checks
  3. Executes unit tests
  4. Creates a test coverage report
name: Node.js CI Pipeline
on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main
jobs:
  build-and-test:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: 18
          cache: "npm"

      - name: Install dependencies
        run: npm ci

      - name: Lint code
        run: npm run lint

      - name: Run tests with coverage
        run: npm test -- --coverage

      - name: Upload coverage report
        uses: actions/upload-artifact@v3
        with:
          name: coverage-report
          path: coverage/

Key Features:

  • npm ci: Uses clean install, which is faster and more reliable for CI environments
  • Caching npm dependencies: Speeds up workflow execution
  • Artifact uploading: Preserves the coverage report for later review

Deploying a Static Website to GitHub Pages

For static websites or documentation, GitHub Pages provides free hosting directly from your repository. Here’s how to automate deployment:

name: Deploy to GitHub Pages
on:
  push:
    branches:
      - main
jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: 16

      - name: Install dependencies
        run: npm ci

      - name: Build static site
        run: npm run build

      - name: Deploy to GitHub Pages
        uses: JamesIves/github-pages-deploy-action@v4
        with:
          folder: build
          branch: gh-pages

Key Features:

  • Third-party action: Uses a community-created action for deploying to GitHub Pages
  • Build output folder: Specifies which directory contains the built website files
  • Target branch: Sets the branch that GitHub Pages will use for hosting

Docker-based Deployment Pipeline

For applications that rely on Docker, you can build and push images to a registry:

name: Docker CI/CD Pipeline
on:
  push:
    branches:
      - main
    tags:
      - "v*"
jobs:
  build-and-push:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v2

      - name: Login to DockerHub
        uses: docker/login-action@v2
        with:
          username: ${{ secrets.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_TOKEN }}

      - name: Extract metadata
        id: meta
        uses: docker/metadata-action@v4
        with:
          images: username/my-app
          tags: |
            type=semver,pattern={{version}}
            type=ref,event=branch            

      - name: Build and push Docker image
        uses: docker/build-push-action@v4
        with:
          context: .
          push: true
          tags: ${{ steps.meta.outputs.tags }}
          labels: ${{ steps.meta.outputs.labels }}
          cache-from: type=registry,ref=username/my-app:buildcache
          cache-to: type=registry,ref=username/my-app:buildcache,mode=max

Key Features:

  • Docker Buildx: Provides enhanced Docker build capabilities
  • Automatic tagging: Creates appropriate image tags based on Git tags or branches
  • Registry caching: Uses Docker’s registry cache to speed up builds

Automating Repetitive Tasks

GitHub Actions excels at automating routine tasks that would otherwise require manual intervention.

Scheduled Database Backups

name: Scheduled Database Backup
on:
  schedule:
    - cron: "0 2 * * *" # Run at 2 AM UTC every day
jobs:
  backup:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Set up PostgreSQL client
        run: |
          sudo apt-get update
          sudo apt-get install -y postgresql-client          

      - name: Create backup
        run: |
          PGPASSWORD=${{ secrets.DB_PASSWORD }} pg_dump \
            -h ${{ secrets.DB_HOST }} \
            -U ${{ secrets.DB_USER }} \
            -d ${{ secrets.DB_NAME }} \
            -F c > backup_$(date +%Y-%m-%d).dump          

      - name: Upload backup to S3
        uses: aws-actions/configure-aws-credentials@v2
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: us-east-1

      - name: Copy file to S3
        run: |
          aws s3 cp backup_$(date +%Y-%m-%d).dump s3://my-backup-bucket/

Key Features:

  • Cron scheduling: Uses cron syntax to schedule daily backups
  • Database dump: Creates compressed PostgreSQL backups
  • Cloud storage: Uploads backups to Amazon S3 for safe storage

Automatic Dependency Updates

Stay on top of dependencies with automated pull requests for package updates:

name: Dependency Updates
on:
  schedule:
    - cron: "0 9 * * 1" # Every Monday at 9 AM UTC
jobs:
  update-dependencies:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: 18

      - name: Update dependencies
        run: npx npm-check-updates -u

      - name: Install updated dependencies
        run: npm install

  schedule:
    - cron: "30 1 * * *" # 1:30 AM UTC every day
jobs:
  stale-management:
    runs-on: ubuntu-latest
    steps:
      - name: Stale issue and PR management
        uses: actions/stale@v8
        with:
          stale-issue-message: "This issue has been automatically marked as stale due to inactivity. It will be closed in 7 days if no further activity occurs."
          stale-pr-message: "This PR has been automatically marked as stale due to inactivity. It will be closed in 14 days if no further activity occurs."
          stale-issue-label: "stale"
          stale-pr-label: "stale"
          days-before-stale: 60
          days-before-close: 7
          days-before-pr-close: 14
          exempt-issue-labels: "pinned,security,enhancement"
          exempt-pr-labels: "pinned,dependencies"

Key Features:

  • Automated labeling: Marks issues and PRs as stale after periods of inactivity
  • Configurable timeframes: Different handling for issues versus PRs
  • Exemption labels: Prevents important issues/PRs from being marked as stale

Advanced Workflow Orchestration

Let’s explore more complex GitHub Actions scenarios for advanced projects.

Microservices Deployment with Multiple Environments

This example demonstrates deploying a microservice to multiple environments (development, staging, production) with different configurations:

name: Microservice Deployment
on:
  push:
    branches:
      - develop
      - staging
      - main
jobs:
  determine-environment:
    runs-on: ubuntu-latest
    outputs:
      env-name: ${{ steps.set-env.outputs.env-name }}
    steps:
      - name: Set environment name
        id: set-env
        run: |
          if [ "${{ github.ref }}" = "refs/heads/main" ]; then
            echo "env-name=production" >> $GITHUB_OUTPUT
          elif [ "${{ github.ref }}" = "refs/heads/staging" ]; then
            echo "env-name=staging" >> $GITHUB_OUTPUT
          else
            echo "env-name=development" >> $GITHUB_OUTPUT
          fi          

  build-and-deploy:
    needs: determine-environment
    runs-on: ubuntu-latest

  push:
    branches:
      - main
    paths:
      - "frontend/**"
      - "backend/**"
      - "common/**"
  pull_request:
    branches:
      - main
    paths:
      - "frontend/**"
      - "backend/**"
      - "common/**"
jobs:
  detect-changes:
    runs-on: ubuntu-latest
    outputs:
      frontend: ${{ steps.filter.outputs.frontend }}
      backend: ${{ steps.filter.outputs.backend }}
      common: ${{ steps.filter.outputs.common }}
    steps:
      - uses: actions/checkout@v3
      - uses: dorny/paths-filter@v2
        id: filter
        with:

        run: |
          migrate -path ./migrations -database "postgres://postgres:postgres@localhost:5432/test?sslmode=disable" up          

      - name: Test migrations (down)
        run: |
          migrate -path ./migrations -database "postgres://postgres:postgres@localhost:5432/test?sslmode=disable" down -all          

  deploy-migrations:
    needs: validate-migrations
    runs-on: ubuntu-latest
    environment: production
    steps:
      - name: Checkout code
        uses: actions/checkout@v3

      - name: Setup Go
        uses: actions/setup-go@v4
        with:
          go-version: "1.21"

      - name: Install migrate tool
        run: go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest

      - name: Apply migrations

Key Features:

  • AWS credential configuration: Securely sets up AWS access
  • S3 deployment: Syncs build artifacts to an S3 bucket
  • CloudFront invalidation: Ensures users see the latest version immediately

Troubleshooting Common Issues

Even the best-designed workflows can encounter issues. Let’s explore common problems and their solutions.

Debugging Failed Workflows

When a workflow fails, follow these steps to diagnose and fix the issue:

1. Check the workflow logs

The GitHub Actions logs provide detailed information about each step’s execution. Look for:

  • Error messages
  • Environment variables
  • Command outputs

2. Enable debug logging

For more verbose logs, add this to your workflow:

env:
  ACTIONS_RUNNER_DEBUG: true
  ACTIONS_STEP_DEBUG: true

3. Use the step.debug action

Add debugging steps to print relevant information:

- name: Debug information
  run: |
    echo "GitHub context: ${{ toJSON(github) }}"
    echo "Job context: ${{ toJSON(job) }}"
    echo "Steps context: ${{ toJSON(steps) }}"
    echo "Runner context: ${{ toJSON(runner) }}"
    echo "Strategy context: ${{ toJSON(strategy) }}"
    echo "Matrix context: ${{ toJSON(matrix) }}"

Common Errors and Solutions

Here are some frequently encountered issues and how to resolve them:

Permission Denied Errors

Issue:

Error: Permission denied (publickey).
fatal: Could not read from remote repository.

Solution: Ensure the GITHUB_TOKEN has sufficient permissions or use SSH keys with appropriate access:

- name: Checkout repository
  uses: actions/checkout@v3
  with:
    ssh-key: ${{ secrets.DEPLOY_KEY }}

Secret Configuration Issues

Issue:

Error: Input required and not supplied: token

Solution: Check that all required secrets are properly configured in the repository settings and correctly referenced in the workflow:

- name: Use API
  env:
    API_TOKEN: ${{ secrets.API_TOKEN }}
  run: |
    if [ -z "$API_TOKEN" ]; then
      echo "API_TOKEN is not set. Please check repository secrets."
      exit 1
    fi
    # Use API_TOKEN here

Resource Limitations

Issue: Build runs out of memory or disk space.

Solution: Optimize your build process or use a larger runner:

jobs:
  build:
    runs-on: ubuntu-latest
    # For larger projects, consider self-hosted runners
    # runs-on: self-hosted
    steps:
      - name: Free disk space
        run: |
          sudo rm -rf /usr/share/dotnet
          sudo rm -rf /opt/ghc
          sudo rm -rf /usr/local/share/boost

Workflow Optimization Techniques

Improve workflow performance and reliability with these techniques:

1. Use faster runners for specific tasks

Choose the right runner for each job:

jobs:
  build:
    runs-on: ubuntu-latest

  deploy:
    runs-on: ubuntu-latest
    # or for performance-intensive tasks:
    # runs-on: ubuntu-latest-4-core

2. Implement smart caching

Cache dependencies and build artifacts to speed up workflow runs:

- name: Cache Gradle packages
  uses: actions/cache@v3
  with:
    path: |
      ~/.gradle/caches
      ~/.gradle/wrapper      
    key: ${{ runner.os }}-gradle-${{ hashFiles('**/*.gradle*', '**/gradle-wrapper.properties') }}
    restore-keys: |
      ${{ runner.os }}-gradle-

3. Split long workflows into separate jobs

Break down complex workflows to improve maintainability and execution time:

jobs:
  build:
    # Build job

  test:
    needs: build
    # Test job

  deploy:
    needs: test
    # Deploy job

Best Practices and Patterns

Let’s conclude with some best practices for GitHub Actions workflows.

Security Best Practices

Protect your workflows and sensitive data with these security practices:

1. Limit permissions for the GITHUB_TOKEN

Restrict token permissions to only what’s needed:

permissions:
  contents: read
  issues: write
  pull-requests: write

2. Use environment protection rules

Set up environment protection rules for sensitive environments:

  1. Go to your repository settings
  2. Navigate to Environments
  3. Create environments (e.g., production)
  4. Add protection rules like required reviewers

Then use these environments in your workflow:

jobs:
  deploy:
    environment: production
    # ...

3. Audit third-party actions

Before using actions from the marketplace:

  • Check the action’s source code
  • Prefer actions with many users/stars
  • Pin actions to a specific SHA for immutability
- name: Checkout
  uses: actions/checkout@a12a3c4d5e6f # Use a specific commit hash

Performance Optimization

Make your workflows faster and more efficient:

1. Use build matrices wisely

Parallelize tests but avoid unnecessary matrix combinations:

strategy:
  matrix:
    os: [ubuntu-latest, windows-latest]
    node: [16, 18]
  fail-fast: true # Stop all jobs if one fails

2. Skip unnecessary workflow runs

Use conditional execution to skip unnecessary workflows:

jobs:
  build:
    if: |
      !contains(github.event.head_commit.message, '[skip ci]') &&
      !contains(github.event.head_commit.message, '[ci skip]')      
    runs-on: ubuntu-latest
    # ...

3. Optimize Docker builds

For Docker-based workflows, use multi-stage builds and caching:

# Dockerfile
FROM node:18 AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

FROM nginx:alpine
COPY --from=builder /app/build /usr/share/nginx/html

Then in your workflow:

- name: Build and push
  uses: docker/build-push-action@v4
  with:
    context: .
    push: true
    tags: myorg/myapp:latest
    cache-from: type=registry,ref=myorg/myapp:buildcache
    cache-to: type=registry,ref=myorg/myapp:buildcache,mode=max

Documentation and Knowledge Sharing

Help your team understand and maintain workflows:

1. Comment your workflows

Add comments to explain complex parts of your workflow:

name: Build and Deploy
on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      # Install dependencies and build the project
      - name: Checkout code
        uses: actions/checkout@v3

      # This step sets up the correct Node.js version and enables caching
      - name: Set up Node.js
        uses: actions/setup-node@v3
        with:
          node-version: 18
          cache: "npm"

      # Clean install ensures consistent builds in CI
      - name: Install dependencies
        run: npm ci

      # Build static assets
      - name: Build project
        run: npm run build

2. Create workflow templates

Create reusable workflow templates in .github/workflow-templates/ to maintain consistency across repositories.

3. Document secrets and requirements

Add a README that explains:

  • Required secrets
  • Environment setup
  • How to trigger workflows manually
