Quick Start

Argo CD implements GitOps. Instead of your CI pipeline pushing deployments to Kubernetes, Argo CD runs inside Kubernetes and continually pulls the latest desired state from your Git repository.

kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

Production Patterns

The App of Apps Pattern

Define a root Argo CD Application custom resource that points to a Git directory containing other Application resources. This allows Argo CD to bootstrap and manage an entire cluster's configuration recursively.

Architecture & Scaling

Self-Healing

Enable Auto-Sync and Self-Healing. If a developer manually runs kubectl edit in production to change a replica count, Argo CD will detect the configuration drift and immediately overwrite it, forcing Git to remain the single source of truth.

Error Recovery

If an automated sync breaks the cluster, simply git revert the bad commit in your repository. Argo CD will instantly detect the rollback in Git and sync the cluster back to the healthy state.

Security Notes

Argo CD requires extremely high privileges in the cluster. Ensure its UI/API is strictly protected via SSO (OIDC/SAML). Limit access using Argo CD's native RBAC to ensure developers can only sync applications in their specific namespaces.

Why use this skill

Use this when your agent works with argo-cd — structured patterns beat pasted docs and prevent common hallucinations.

AI pitfalls

• Hardcoding region or account IDs
• Missing IAM least-privilege on cloud resources
• Confusing similar service names (e.g. S3 vs CloudFront)

Production checklist

• [ ] Secrets in environment variables, not source code
• [ ] Error handling and logging in place
• [ ] Rate limits and timeouts configured
