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.

Troubleshooting "vSphere with Tanzu" Integration in VCD 10.2

During my first attempts to integrate "vSphere with Tanzu" into VMware Cloud Director 10.2, I had a couple of issues. The integration just wasn't as smooth as I expected and many configuration errors are not mitigated in the GUI. Also, there are a lot of prerequisites to strictly follow.

In this article, I'm going through the issues I had during the deployment and how to solve them. Read more »

Configure "vSphere with Tanzu" in VMware Cloud Director 10.2

With the release of Cloud Director 10.2, you can now integrate "vSphere with Tanzu" Kubernetes Clusters into VMware Cloud Director. That enabled you to create a self-service platform for Kubernetes Clusters that are backed by the Kubernetes integration in vSphere 7.0.

This article explains how to integrate vSphere with Tanzu in VMware Cloud Director 10.2

Introducing Simplified Deployment for VMware Cloud Director 10.2

With the release of Cloud Director 10.2, VMware aims to make the deployment easier and more robust with a new deployment UI that includes error-checking. In previous versions, you had to provide the initial configuration with vAPP options during the OVA deployment. When there was a problem, which was very common, especially with the NFS share, you had to redeploy the system. Redeploying the appliance multiple times was was very time-consuming.

In Cloud Director 10.2, the operation has been split into 2 stages, as you know it from the vCenter Server. You first deploy the OVA with some basic settings that are not error-prone and then log into a web interface to do the actual Cloud Director configuration like setting up the NFS share and create the Administrator Account.

This article does a quick review of the installation using my OVF Helper Scripts and the new two-stage appliance system setup.
