SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents manual Kubernetes resource modifications in ArgoCD-managed environments, enforcing strict GitOps principles and ensuring desired state consistency. It educates users on the "ArgoCD Way," drastically reducing configuration drift and deployment errors.

Core Features & Use Cases

  • Git as Single Source of Truth: Guides on updating Kubernetes resources exclusively via Git, letting ArgoCD handle the actual deployment and synchronization.
  • ArgoCD CLI Commands: Provides essential commands for application management, manual sync triggers, and debugging deployment issues.
  • Emergency Override Guidance: Offers a controlled, temporary process for manual changes, emphasizing quick reconciliation with the Git repository.
  • Use Case: A team member accidentally modifies a Kubernetes deployment directly with kubectl edit. This skill immediately reminds them that ArgoCD will revert this change and guides them to update the source repository instead, maintaining the GitOps workflow and preventing configuration drift.

Quick Start

Modify your Kubernetes manifests or Helm charts in your Git repository

git add k8s/ git commit -m "update deployment configuration" git push

Manually trigger ArgoCD sync (if automated sync is paused or for immediate update)

argocd app sync my-app

Check the synchronization status and health of your application

argocd app get my-app

FAQPage Schema
How do I prevent manual kubectl changes from overriding my Kubernetes deployments?

GitOps with ArgoCD enforces Git as the single source of truth—any manual kubectl edits are automatically reverted during sync. Update your manifests in Git instead, then ArgoCD applies the changes, eliminating configuration drift and keeping desired state consistent.

What's the best way to structure Kubernetes manifests for ArgoCD deployment?

Define Kubernetes resources in Git repositories and manage them through ArgoCD Application CRs rather than direct kubectl applies. ArgoCD syncs manifests from Git automatically with prune and selfHeal enabled, ensuring your cluster always matches the repository state.

Can I still make emergency changes to Kubernetes if ArgoCD is managing deployments?

Yes, but temporary manual changes should be followed by quick reconciliation with your Git repository. ArgoCD will revert manual edits on the next sync, so emergency overrides must be treated as temporary—always update Git to persist the change.

How do I manually trigger an ArgoCD sync when automated sync is paused?

Use the ArgoCD CLI command `argocd app sync my-app` to manually synchronize an application. You can also check sync status and application health with `argocd app get my-app` to verify deployment state against Git.

Why does ArgoCD automatically revert my kubectl edits?

ArgoCD enforces GitOps by treating Git as the authoritative source. When you enable automated sync with prune and selfHeal, any cluster drift—including manual kubectl changes—is automatically corrected to match the Git repository, preventing inconsistent state.
