Kubeadm control plane

Using the Kubeadm control plane type to manage a control plane provides several ways to upgrade control plane machines.

Kubeconfig management

KCP will generate and manage the admin Kubeconfig for clusters. The client certificate for the admin user is created with a valid lifespan of a year, and will be automatically regenerated when the cluster is reconciled and has less than 6 months of validity remaining.

Upgrades

See the section on upgrading clusters.
