argocd is the official command-line interface (CLI) for ArgoCD, a declarative continuous delivery platform for Kubernetes based on GitOps principles.

ArgoCD follows the GitOps pattern: applications are described declaratively via Kubernetes manifests or Helm charts stored in Git repositories. The ArgoCD server continuously monitors these repositories, compares the desired state (Git) with the live state (Kubernetes cluster), and automatically applies changes to achieve synchronization.

The CLI enables users to manage ArgoCD resources such as applications, clusters, projects, repositories, and secrets. Common operations include creating, syncing, and deleting applications; adding clusters; managing RBAC; and logging in with various auth methods. It supports both interactive use and automation in CI/CD pipelines.

Key features include multi-tenancy support, application health checks, rollouts with analysis, and integration with tools like Helm, Kustomize, and Jsonnet. Designed for operators and developers, it simplifies Kubernetes deployments by leveraging Git as the single source of truth.

Requires a running ArgoCD server and kubectl access to target clusters.

Requires running ArgoCD server; most operations need auth token or login. Not a standard distro package—install via script or package manager. Subcommands have additional flags; use argocd <subcommand> --help for details.

Originally developed by Intuit in 2018 as open-source GitOps tool for Kubernetes. Joined CNCF as Sandbox project in 2020, graduated to Incubating in 2022. CLI evolves with server releases; current v2.12+ emphasizes security and multi-cluster support.
