What This Does

Helm is the package manager for Kubernetes. Simplifies deploying complex applications with pre-configured templates.

Pro Tips

  • 1
    Helm 3 doesn't require Tiller (server component)
  • 2
    Package managers (safer): Mac: brew install helm | Ubuntu/Debian: apt install helm | Windows: choco install kubernetes-helm
  • 3
    Helm works with your kubectl context
  • 4
    Helm charts are like apt packages for Kubernetes
  • 5
    Verify kubectl connection before installing Helm

Common Mistakes to Avoid

  • ⚠️Using curl | bash without checking script contents first
  • ⚠️Not verifying kubectl is connected to correct cluster before installing
