Argo CD

Declarative GitOps continuous delivery for Kubernetes.

Argo CD is a declarative, GitOps-based continuous delivery tool for Kubernetes that synchronizes application state defined in Git repositories with live Kubernetes clusters. It continuously monitors running applications and compares them against the desired state in Git, automatically syncing or alerting on drift. Argo CD provides a web UI and CLI for visualizing application health, resource topology, and deployment history. It supports multiple configuration management tools including Helm, Kustomize, Jsonnet, and plain YAML, and can manage applications across multiple clusters. With features like automated sync policies, SSO integration, role-based access control, and Prometheus metrics, Argo CD has become the standard GitOps tool for organizations running Kubernetes at scale.
