Tanzu Kubernetes cluster is created by invoking a Tanzu Kubernetes Grid service declarative API. Once the cluster is created, you can manage and deploy workloads to it by running the Kubectl command.

To create TKG clusters:

1. Download and install the Kubernetes CLI tool for vSphere, as mentioned in the previous section.
2. Log in to the namespace context as follows:

kubectl-vsphere.exe login --insecure-skip-tls-verify --vsphere-username

3. Verify the control plane and storage class:

kubectl get 

kubectl get sc

4. Switch context to the supervisor namespace where you want provision Tanzu Kubernetes Cluster:

Kubect config get-contexts

5. Construct the YAML file for provisioning Tanzu Kubernetes Cluster and save it as <cluster-name.yaml>; for example:

apiVersion: run.tanzu.vmware.com/v1 kind: TanzuKubernetesCluster metadata:

name: tkg-cluster-01 namespace: test-ns-1

spec:

distribution: version: v1.18.5

topology: controlPlane:

count: 1

6. Provision the cluster by running the apply command:

Kubectl apply -f <cluster-name>.yaml

7. Verify the provisioned cluster:

Kubectl cluster-info

Kubectl get nodes 

Kubectl get ns 

Kubectl api-resources

8. At step 5, the yaml file specifies 1 control plane and 3 worker nodes. This can be verified at vCenter under Namespaces.
