System Documentation

What problem does it solve?

This Skill automates the management of Kubernetes PKI certificates, ensuring cluster stability by proactively handling expirations and renewals for kubeadm-based clusters.

Core Features & Use Cases

  • Certificate Expiry Monitoring: Checks for upcoming certificate expirations across management and workload clusters.
  • Automated Renewal: Manages automatic certificate rotation for Cluster API-provisioned clusters and provides steps for manual renewal on management clusters.
  • Status Reporting: Generates reports on certificate status and required actions.
  • Use Case: When an alert indicates a Kubernetes certificate is nearing expiration, this Skill can be used to verify the status, confirm the renewal mechanism (automatic via CAPI or manual), and execute the necessary renewal steps to prevent service disruption.

Quick Start

Check the expiration status of all certificates for the infra-k8s-idc cluster.
