CI/CD

If you've ever merged a pull request and watched tests, builds, and deployments happen automatically, you've seen a CI/CD pipeline at work. In this guide we break down what each stage does, why it matters, and how to design a pipeline you can trust.

GitHub Actions looks simple until you need matrix builds, reusable workflows, and environment protection rules. This is the deeper tour — the syntax and features you reach for after the quickstart.

GitHub Actions, GitLab CI, and Jenkins all automate the same job — build, test, ship — but they make very different trade-offs. Here's how to choose.

GitOps manages infrastructure and deployment pipelines the same way we manage source code: Git becomes the single source of truth for declarative infrastructure and applications. It's an extension of DevOps that makes operations developer-centric — pull requests are your change-management system, and an agent inside the cluster does the deploying. This guide covers the four GitOps principles, why the pull model beats push, and a complete hands-on setup with Argo CD — the declarative, GitOps continuous delivery tool for Kubernetes.
