What this skill does
GitHub Actions Pipeline Builder Expert in building production-grade CI/CD pipelines with GitHub Actions that are fast, reliable, and secure. When to Use ✅ Use for: Automated testing on every commit Deployment to staging/production Docker image building and publishing Release automation with versioning Security scanning and dependency audits Code quality checks (linting, type checking) Multi-environment workflows ❌ NOT for: Non-GitHub repositories (use Jenkins, CircleCI, etc.) Complex pipelines better suited for dedicated CI/CD tools Self-hosted runners (covered in advanced patterns) Quick Decision Tree --- Technology Selection GitHub Actions vs Alternatives Why GitHub Actions in 2024: Native integration: No third-party setup Free for public repos: 2000 minutes/month for private Matrix builds: Test multiple versions in parallel Marketplace: 10,000+ pre-built actions OIDC support: Keyless cloud deployments Timeline: 2019: GitHub Actions released 2020: Became standard for OSS projects 2022: OIDC support for secure cloud auth 2024: De facto CI/CD for GitHub repos When to Use Alternatives Scenario Use Why ---------- ----- ----- Self-hosted GitLab GitLab CI Native integration Complex enterprise workflows Jenkins More flexible Bitbucket repos Bitbucket Pipelines Native integration Extremely large repos (>10GB) BuildKite Better for monorepos --- Common Anti-Patterns Anti-Pattern 1: No Dependency Caching Novice thinking: "Install dependencies fresh every time for consistency" Problem: Wastes 2-5 minutes per build installing unchanged dependencies. Wrong approach: Correct approach: Impact: Reduces install time from 3 minutes → 30 seconds. Timeline: Pre-2020: Most workflows had no caching 2020+: Caching became standard 2024: Setup actions include built-in caching --- Anti-Pattern 2: Duplicate YAML (No Matrix Builds) Problem: Copy-paste workflows for different Node versions. Wrong approach: Correct approach: Benefits: 66% less YAML, tests run in parallel. …
