What is ArgoCD ArgoCD is a declarative, GitOps continuous delivery tool for Kubernetes.
Your Git repository is the single source of truth; ArgoCD watches it and continuously syncs the cluster to match the desired state.
1Git repo ──► ArgoCD ──► Kubernetes cluster Key concepts Application — a group of Kubernetes resources described in Git. Project — groups applications and scopes their permissions. Source — the repo to render from (git, helm, kustomize, …). Sync — reconcile the live cluster with the desired state.

Don’t commit plaintext secrets to Git — pair ArgoCD with an external secret manager (Vault, sealed-secrets, SOPS/ksops).
