Hi everyone

I am deploying a TKC cluster using v1alpha2 API on vSphere 7U3.

The control plane and worker VMs are deploying, but the cluster pending on Creating phase.

When I describe the cluster using:

kubectl describe tkc tkgs-prod-cluster -n ns-prod

I am getting:
......
Conditions:
Last Transition Time: 2023-02-16T05:54:40Z
Message: node pools [] are unknown, [] are failed, [worker-nodepool-a1] are updating
Reason: NodePoolsUpdating
Severity: Info
Status: False
Type: Ready
..............

I have created a cluster with 1 control plane, 3 worker nodes. but when I run command kubectl get nodes inside the cluster it lists as fllowing:

tkgs-prod-cluster-control-plane-9w8zz Ready control-plane,master 32m v1.23.8+vmware.3
tkgs-prod-cluster-worker-nodepool-a1-7bq9v-65b6485f56-9k72d Ready <none> 28m v1.23.8+vmware.3
tkgs-prod-cluster-worker-nodepool-a1-7bq9v-65b6485f56-bq89s Ready <none> 28m v1.23.8+vmware.3

there is only 2 worker nodes! but in vSphere inventory I see 3 worker VMs

when I run kubectl get po -A all the pods are running and fine.

Anyone knows what can be the issue?

Late reply but you can get some more information regarding the provisioning of the virtual machines for the kubernetes cluster by doing a kubectl get machines -n <your vsphere namespace> while being on the supervisor context.

There is a pretty nice troubleshooting guide available here: https://core.vmware.com/blog/tanzu-kubernetes-grid-service-troubleshooting-deep-dive-part-3
