Reconcile/Recreate tmc-agent-installer on a TKGs Supervisor cluster.

Products

• VMware vSphere Kubernetes Service

Issue/Introduction

You find the tmc-agent-installer resources and/or namespace svc-tmc-cX have been deleted, modified or moved. So Tanzu Mission Control cannot be installed.

Environment

vCenter 8.0.3

Supervisor: v1.29.7

Cause

The tmc-agent-installer resources and/or namespace have been deleted, modified or moved

Resolution

1. On vCenter, confirm that the Supervisor cluster name, in this example it is   "domain-c9"

/opt/vmware/vpostgres/current/bin/psql -U postgres -d VCDB -c "select cluster from wcp.cluster_db_configs;"

2. On the Supervisor the TMC namespace,  where the tmc-agent-installer is set up by default, should in this case be  be svc-tmc-c9. The resources are defined in the yaml file: /usr/lib/vmware-wcp/objects/PodVM-GuestCluster/70-tmc-agent-installer/tmc-agent-installer.yaml.

    Confirm that it has the correct Namespace, svc-tmc-c9, by running the command 

    grep svc-tmc-c9 /usr/lib/vmware-wcp/objects/PodVM-GuestCluster/70-tmc-agent-installer/tmc-agent-installer.yaml

You should see output like this

# grep svc-tmc-c9 /usr/lib/vmware-wcp/objects/PodVM-GuestCluster/70-tmc-agent-installer/tmc-agent-installer.yaml
  name: svc-tmc-c9
  namespace: svc-tmc-c9
  namespace: svc-tmc-c9
  namespace: svc-tmc-c9
  namespace: svc-tmc-c9
  namespace: svc-tmc-c9
  namespace: svc-tmc-c9

3. There are two options: Reconcile the base tmc-agent-installer resources or Delete and Recreate the base tmc-agent-installer resources

a. To reconcile the base tmc-agent-installer resources  you can you kubectl

kubectl apply -f /usr/lib/vmware-wcp/objects/PodVM-GuestCluster/70-tmc-agent-installer/tmc-agent-installer.yaml

b. To Delete and Recreate the base tmc-agent-installer resources

kubectl delete -f /usr/lib/vmware-wcp/objects/PodVM-GuestCluster/70-tmc-agent-installer/tmc-agent-installer.yaml

kubectl apply -f /usr/lib/vmware-wcp/objects/PodVM-GuestCluster/70-tmc-agent-installer/tmc-agent-installer.yaml
