CI/CD with GitHub Actions
summary
Step-by-step guide to GitHub Actions that shows real YAML examples, GitHub-hosted runners (Ubuntu/Mac/Windows), and how workflows use workflow_dispatch triggers, jobs/steps with matrix builds, and the needs keyword for dependencies. Secrets, environments, and the cache action are used; OpenID Connect authenticates to Azure to create an ephemeral resource group (example: PR4) and deploy a live website that validates successfully. Marketplace actions (checkout, build-push, super-linter) plus the local testing tool act are demonstrated so pipelines can be iterated and run locally before pushing.
