Argo CD

A declarative GitOps continuous delivery tool for Kubernetes that syncs cluster state with manifests stored in Git.

Definition

Argo CD runs in the cluster, watches Git repositories (plain YAML, Kustomize, Helm), compares desired and live state, and shows applications as Synced or OutOfSync. Auto-sync with self-heal reverts manual drift.

Example

An Argo CD Application points at the k8s/prod path of a repo and auto-syncs on every merge.

Exam tip

Argo CD is pull-based GitOps; credentials stay in the cluster rather than the CI system.
