Expose a Tanzu Kubernetes Grid Cluster

Follow these steps to expose a Tanzu Kubernetes Grid cluster using VMware Cloud Director Container Service Extension.

To expose a TKGm cluster, it is necessary to edit the specification section in the TKGm cluster configuration file before cluster creation.

Note: It is not possible to expose the cluster after cluster creation.

Procedure

To generate a sample 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: '*'

In the spec section of the TKGm cluster configuration file, set expose to True.
```
expose : True
```
To create a TKGm cluster, enter the following command in vcd cse:
```
vcd cse cluster apply <tkgm_cluster.yaml>
```

Hide a Tanzu Kubernetes Grid Cluster

Follow these steps to deactivate the expose functionality and hide a Tanzu Kubernetes Grid cluster.

Procedure

In vcd cse, in the spec section in the TKGm cluster configuration file, set expose to False:
```
expose : False
```
Enter the following command to apply updates:
```
vcd cse cluster apply <tkgm_cluster.yaml>
```
