CI/CD Platform Engineering

A book-shaped table of contents for CI/CD platform engineering: pipeline foundations, build/artifact/delivery platforms, GitHub Actions end to end (workflow mechanics through enterprise governance), Argo Workflows, Tekton, Jenkins, release engineering, platform security, observability, reliability, enterprise governance, and MAANG interview preparation — cross-linking existing tech/kubernetes/platform-engineering-fundamentals/system-design notes instead of duplicating them.

1 — Deployment Architecture

Contrasts push- and pull-based deployment, introduces GitOps and deployment controllers, and covers environment promotion — see tech/gitops.md, tech/argocd.md, and tech/fluxcd.md for the tool-level mechanics.

2 — Environment Management

Covers how a delivery platform manages the development, testing, staging, production, and ephemeral-environment tiers as first-class platform resources.

4 — Progressive Delivery

Covers feature flags, automated verification, traffic shifting, and progressive rollouts as the mechanics behind safely decoupling deploy from release.

8 — Matrix Builds

Explains matrix strategy fan-out, dynamic matrices computed at runtime, include/exclude overrides, and common OS and language matrix patterns.
