Kubernetes Certificates and cert-manager Monitoring

Last updated on 09 July, 2024

A Kubernetes certificate is used to secure and encrypt communication within a Kubernetes cluster. For more information, see Certificate resource from cert-manager documentation.

cert-manager is an add-on that creates TLS certificates for workloads in your Kubernetes or OpenShift cluster and renews them before expiration. For more information, see cert-manager from cert-manager documentation.

  • Ensure you have LM Container enabled.
  • You have installed cert-manager Helm chart. For more information, see Installing with Helm from cert-manager documentation.
  • You have installed LM Container Helm Charts 8.1.0 or later.
  • You have enabled the Kubernetes_Certificate and Kubernetes_Certificate_Manager datasources.
