GitHub Actions — Zero to Hero
Master CI/CD with GitHub Actions from your first workflow to production deployments on AKS. Learn YAML pipelines, secrets management, reusable workflows, security hardening, and real-world deployment patterns.
Start Learning →🔰 Basics
Understand what CI/CD is, why automation matters, how GitHub Actions works, and the anatomy of a workflow YAML file.
What is CI/CD
Continuous Integration & Continuous Deployment explained. Why every team automates, and what problems CI/CD solves.
GitHub Actions Fundamentals
How GitHub Actions works: events, workflows, jobs, steps, actions, and the marketplace ecosystem.
Workflow YAML Anatomy
Line-by-line breakdown of a workflow file. Triggers, jobs, steps, uses, run, env, and conditional execution.
Runners & Environments
GitHub-hosted vs self-hosted runners, runner images, labels, and deployment environments with protection rules.
⚙️ Intermediate
Build real pipelines — compile code, run tests, manage secrets, create reusable workflows, and optimize with caching.
Building & Testing
Build Docker images, run unit tests, generate code coverage, lint code, and publish test results.
Secrets & Variables
Repository secrets, environment secrets, organization secrets, configuration variables, and OIDC tokens.
Reusable Workflows
Composite actions, reusable workflows, workflow_call, inputs/outputs, and organization-wide templates.
Artifacts & Caching
Upload/download artifacts, dependency caching, Docker layer caching, and optimizing workflow speed.
🚀 Advanced
Deploy to AKS with Helm, harden security with OIDC and permissions, and master matrix strategies for complex builds.
Deploy to AKS with Helm
Build → push to ACR → deploy to AKS via Helm. Multi-environment promotion, rollbacks, and GitOps integration.
Security & Permissions
GITHUB_TOKEN permissions, OIDC for Azure/AWS, branch protection, environment approvals, and supply chain security.
Matrix & Advanced Patterns
Matrix strategies, dynamic matrices, conditional jobs, concurrency groups, and workflow orchestration.
🧪 Hands-on Labs
Build a complete production pipeline, debug real failures, and prepare for CI/CD interview questions.
Build a Full Pipeline
End-to-end: lint → test → build Docker → push ACR → deploy Helm to AKS → smoke test. Complete lab.
Debugging Workflows
Fix YAML syntax errors, permission denials, secret misconfigs, runner failures, and action version issues.
Interview Preparation
40+ real interview questions on CI/CD concepts, GitHub Actions architecture, pipelines, and troubleshooting.
