ArgoCD

Development

Definitions

  1. A declarative GitOps continuous delivery tool for Kubernetes that keeps cluster state synchronized with Git repositories. ArgoCD watches Git repos containing Kubernetes manifests, Helm charts, or Kustomize configurations and automatically applies changes to the cluster when commits are pushed. Its web UI provides a real-time visualization of application health, sync status, and resource topology. ArgoCD enforces the GitOps principle that Git is the single source of truth for infrastructure: what's in the repo is what's running in the cluster, and any drift is detected and can be automatically corrected. It became the most widely adopted GitOps tool in the Kubernetes ecosystem, often paired with Argo Workflows and Argo Rollouts for progressive delivery.

    In plain English: A tool that automatically deploys your applications to Kubernetes whenever you push changes to Git. It keeps your cluster in sync with your code repository and shows you exactly what's running.

    Example: We push Helm chart changes to Git and ArgoCD syncs them to our clusters within minutes. No more running kubectl apply manually.
