Argo CD

What It Is

A GitOps tool for Kubernetes that synchronizes cluster state with a Git repository.

Core Ideas

• application
• sync
• desired vs live state
• auto-sync and manual sync
• drift detection

Core Workflow

1. Manifests or Helm values live in Git.
2. Argo CD tracks the repository.
3. A Git change becomes the source of truth for the cluster.

Practice

• Argo CD works best when the team already operates through disciplined Git workflows.
• Do not mix routine kubectl edit changes with GitOps-based management.
