What is ArgoCD?

ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes. It automates the deployment of applications to Kubernetes clusters by continuously monitoring Git repositories and synchronizing the desired application state with the live cluster state. ArgoCD follows the GitOps pattern where Git is the single source of truth for application configurations. It provides a web UI and CLI for managing applications, supports multiple config management tools including Helm, Kustomize, and plain YAML, and offers automated or manual sync strategies. ArgoCD includes features like health assessment, automated pruning, rollback capabilities, and multi-cluster management. It ensures that deployed applications match the configuration stored in Git repositories.
