What is ArgoCD?

A declarative GitOps continuous delivery tool for Kubernetes that automatically syncs cluster state with Git repositories.

ArgoCD follows the GitOps principle: Git is the single source of truth for desired cluster state. It monitors Git repositories and automatically applies changes to Kubernetes clusters, ensuring the deployed state matches the declared state.

Features include automated sync, manual sync with approval, drift detection, rollback, multi-cluster management, SSO integration, and a web UI for visualization. ArgoCD is the leading GitOps tool for Kubernetes environments.
