Question

City platform runs kubeadm init and must pass a pod-network CIDR that will not clash with the civic WAN. What should admins do?

Accepted Answer

Choose a --pod-network-cidr (or equivalent config) that is unique relative to existing civic routes and matches CNI expectations. — Pick a Pod neighborhood address block that does not collide with the city’s WAN streets. Pass that CIDR into kubeadm so the CNI can pave routes cleanly. Overlapping with WAN or with the Service range creates routing headaches.

Answer

Reuse the WAN CIDR so Pods can be addressed without NAT anywhere.

Answer

Omit any pod CIDR and let every Pod take a random public IP from the ISP.

Answer

Set the pod CIDR equal to the Service cluster IP range to save address space.
