Change TKG Cluster Service and Pod CIDR in Cloud Director 10.2

A major problem when deploying "vSphere with Tanzu" Clusters in VMware Cloud Director 10.2 is that the defaults for TKG Clusters are overlapping with the defaults for the Supervisor Cluster configured in vCenter Server during the Workload Management enablement.

When you deploy a Kubernetes Cluster using the new Container Extension in VCD 10.2, it deploys the cluster in a namespace on top of the Supervisor Cluster in the vCenter Server. The Supervisor Clusters IP address ranges for the Ingress CIDRs and Services CIDR must not overlap with IP addresses 10.96.0.0/12 and 192.168.0.0/16, which is the default for TKG Clusters. Unfortunately, 10.96.0.0 is also the default when enabling workload management so the deployment will fail when you stick to the defaults. The following error message is displayed when you have overlapping networks:

spec.settings.network.pods.cidrBlocks intersects with the network range of the external ip pools in network provider's configuration
spec.settings.network.pods.cidrBlocks intersects with the network range of the external ip pools LB in network provider's configuration

This article explains a workaround that you can apply when deleting and reconfiguring the Namespace Management with non-overlapping addresses is not an option.
