About:
cmctl is a command-line tool designed to manage cert-manager installations and resources within Kubernetes clusters. It streamlines the process of troubleshooting, issuing, and renewing certificates directly from the terminal. This tool is essential for DevOps engineers maintaining secure TLS configurations in cloud-native environments.
Key Features:
  • Install and upgrade cert-manager on Kubernetes
  • Convert Kubernetes manifests to cert-manager CRDs
  • Check certificate readiness and status
  • Approve and deny certificate signing requests (CSRs)
Use Cases:
  • Debugging expired or stuck certificates in a cluster
  • Migrating legacy TLS configurations to cert-manager
Alternatives:
  • kubectl – Standard kubectl can manage cert-manager CRDs, but cmctl provides specialized commands for installation and troubleshooting.
