GitHub Actions CI/CD

Overview

GitHub Actions provides powerful CI/CD capabilities directly within GitHub repositories. This skill should be invoked when setting up continuous integration and deployment workflows to automate testing, building, and deploying applications.

Core Principles

• Workflow as Code: Define pipelines in version-controlled YAML files
• Trigger Control: Configure precise triggers for when workflows run
• Job Isolation: Separate concerns into independent jobs
• Secret Management: Use GitHub Secrets for sensitive data

Preparation Checklist

• Identify CI/CD requirements (test, build, deploy)
• Create .github/workflows/ directory
• Determine trigger events (push, PR, schedule)
• Plan job dependencies and matrix strategies
