Kubernetes uses two internal IP ranges, either of which can overlap and conflict with the underlying infrastructure, thus requiring custom IP ranges.
- The pod network
Either Calico or Azure IPAM services gives each Kubernetes pod an IP address in the default
192.168.0.0/16range. To customize this range, during MKE installation, use the
--pod-cidrflag with the ucp install command.
- The services network
You can access Kubernetes services with a VIP in the default
10.96.0.0/16Cluster IP range. To customize this range, during MKE installation, use the
--service-cluster-ip-rangeflag with the ucp install command.
