opened on May 24, 2025

Some time ago the v1beta4 version of the kubeadm API added ClusterConfiguration.CertificateValidityPeriod and ClusterConfiguration.CACertificateValidityPeriod, but those fields currently are not surfaces in KubeadmConfig / KubeadmControlPlane CRD.

When we will consider adding those fields, we should also consider possible impacts on certificate management, e.g. https://cluster-api.sigs.k8s.io/tasks/certs/auto-rotate-certificates-in-kcp, may also kubeconfig certificate renewal and more
