Learn GITHUB-ACTIONS with Real Code Examples

Workflow file defines jobs and steps

Jobs run on runners (GitHub-hosted or self-hosted)

Steps within jobs can use actions or shell commands

Triggers initiate workflows based on repository events

Secrets, artifacts, and caching enable secure and efficient runs

Workflow YAML defines jobs and steps

Runner executes each job

Steps execute actions or scripts

Artifacts, caches, and outputs manage workflow state

Triggers initiate workflow execution based on events

Event-driven CI/CD pipelines

Matrix builds for multi-environment testing

Reusable actions for DRY principles

Integration with external services and APIs

Self-hosted or GitHub-hosted runner architectures

CI/CD pipeline for Node.js application

Python package testing across multiple Python versions

Docker build and deployment workflow

Multi-repo orchestration for microservices
