We are currently running NKE and are looking to move to NKP but have a doubt about the subnet requirements.
NKE is currently running with multiple Kubernetes Clusters in a single Subnet. Is it supported and valid to continue in this way with NKP?
Ideally, we would like to build the NKP clusters in the same subnet as NKE for the migration work rather than commission a new subnet. The subnet is suitably large, and we use Calico CNI for Networking.

Hi jwright1,
yes, you can run multiple NKP clusters in the same subnet if you have enough available ip addresses.
You can even run them on the NKE subnet.
You will need IPAM or DHCP for a subset of the subnet to assign addresses dynaically to the NKP cluster nodes as they get provisioned as well as a certain mount of static IP addresses for api VIP as well a load balancer range. this will be required for each cluster you want to create.
You’ll find a basic example here : https://github.com/nutanixdev/nkp-quickstart?tab=readme-ov-file#nkp-on-nutanix-high-level-design
