A court cluster must prepare for later HA expansion. What should be set during initial kubeadm planning for a stable API endpoint?
Select an answer to reveal the explanation.
Short Explanation
Pick the courthouse’s permanent street address before you add more front doors. A stable controlPlaneEndpoint—DNS or VIP—keeps certificates and join clients sane when HA arrives. Ephemeral node IPs make every expansion painful.
Full Explanation
kubeadm’s controlPlaneEndpoint should be a stable DNS name or virtual IP that front-ends control-plane nodes. Setting it early ensures certificates and join configurations remain valid as you add HA control-plane members. Tying clients to a single DHCP node IP or to etcd peer URLs is fragile and incorrect for the Kubernetes API endpoint.
