Create a Tanzu Kubernetes Grid Cluster in VMware Cloud Director Container Service Extension Client

To create a Tanzu Kubernetes Grid (TKGm) cluster using VMware Cloud Director Container Service Extension client, it is necessary to generate a cluster configuration file and use the cluster apply command.

Procedure

To generate the TKGm cluster configuration file, open vcd-cse and enter the following command:

vcd cse cluster apply -s --tkg

The following code is an example of a TKGm cluster configuration yaml file:

apiVersion: cse.vmware.com/v2.1
kind: TKGm
metadata:
  name: tkgm1
  orgName: org1
  site: https://vcd.com
  virtualDataCenterName: ovdc1
spec:
  distribution:
    templateName: ubuntu-2004-kube-v1.21.8+vmware.1-tkg.2-ed3c93616a02968be452fe1934a1d37c
    templateRevision: 1
  settings:
    network:
      expose: true
    ovdcNetwork: ovdc1_nw
    rollbackOnFailure: true
    sshKey: 'ssh-key'
    csi:
    - defaultK8sStorageClass:
        filesystem: ext4
        k8sStorageClassName: my-storage-class
        useDeleteReclaimPolicy: true
        vcdStorageProfileName: '*'
  topology:
    controlPlane:
      count: 1
      storageProfile: '*'
    workers:
      count: 1
      storageProfile: '*'

To create a TKGm cluster, enter the following command in vcd cse:
```
vcd cse cluster apply <tkgm_cluster.yaml>
```

Results

Your TKGm cluster is created.

If you want to scale up worker nodes, you can use the following commands in vcd cse:

vcd cse cluster apply <resize_cluster.yaml> (resizes the specification on the resource specified).

Note: TKGm clusters do not support scaling down worker nodes, scaling NFS nodes or upgrades.
