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 — Argo Workflows

Covers Argo Workflows' architecture, DAG-based workflow definitions, event integration, and scheduling as a Kubernetes-native CI/CD orchestration engine.

3 — Jenkins Platform

Covers Jenkins controller architecture, agents, shared libraries, and the modern Jenkins (Configuration-as-Code, cloud-native agents) evolution.

4 — Choosing the Right Platform

Compares GitHub Actions, Argo Workflows, Tekton, and Jenkins against organizational constraints, and covers hybrid models that combine more than one.

8 — Matrix Builds

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