GitOps Explained: Managing Infrastructure as Code

What is GitOps?

GitOps is a set of practices to manage infrastructure and application configurations using Git, an open-source version control system. It works by using Git as a single source of truth for declarative infrastructure and applications.

Principles of GitOps

1. Declarative: The entire system described declaratively.
2. Versioned: The canonical desired system state versioned in Git.
3. Automated: Approved changes that can be automatically applied to the system.
4. Self-healing: Software agents to ensure correctness and alert on divergence.

Tools

ArgoCD and Flux are the two most popular GitOps operators for Kubernetes.
