## TL;DR

GitOps (Weaveworks, 2017) is an operational framework using Git as the single source of truth for declarative infrastructure and applications. Git commits trigger automated deployment. Tools: Argo CD, Flux CD. GitOps applies DevOps best practices (version control, code review, CI/CD) to infrastructure.

## Core Explanation

Principles: declarative (desired state in Git), versioned/immutable (history and rollback), pulled automatically (agent reconciles), continuously reconciled (drift detection). Argo CD: syncs Kubernetes manifests from Git to cluster. Flux: pulls Git repo, applies changes. Pull vs. Push: GitOps is pull-based (agent in cluster) — more secure than push-based CI/CD.
