Add a new workload cluster in vSphere with Tanzu

After registering a vSphere Supervisor, you can use Tanzu Platform for Kubernetes to provision resources and create a workload cluster.

Before you begin

Before you begin, fulfill these prerequisites:

• Obtain a vSphere with Tanzu deployment.
• Register a vSphere Supervisor. For more information, see Register a Supervisor in Tanzu Platform.
• Obtain the necessary permissions to create a cluster.
• Create a cluster group in which to place the cluster.
• Ensure that each node has at least 4 vCPUs and 8 GB of RAM for your workload clusters.

• To enable Tanzu Application Engine, ensure that your cluster meets the following extra requirements:

  • Ensure that Tanzu Kubernetes Grid Service Supervisor is running in vSphere with Tanzu (vSphere 7.0 P09 and later).
  • Ensure that your workload cluster has at least 3 nodes, each with 4 vCPUs and 16 GB of RAM.

• Do one of the following:

  • Install and log in with the Tanzu CLI. For more information, see the VMware Tanzu CLI Documentation.
  • Log in to Tanzu Platform hub.

Add a new workload cluster

You can add a new workload cluster by using Tanzu Platform hub.

Tanzu Platform hub

Perform the following steps in Tanzu Platform hub:

1. In Tanzu Platform hub, select the Project in which you want to add a new cluster.
2. In the left navigation pane, click to expand Infrastructure and then click Kubernetes Clusters.
3. On the Kubernetes Clusters page, click the Clusters tab.
4. Click Add Cluster and then click Create Tanzu Kubernetes Grid cluster.
5. Select the management cluster and provisioner (vSphere namespace) in which you want to create the workload cluster.
6. Click Next.

7. Enter a name for the cluster, and specify the cluster group.

   The cluster name must start and end with a letter or number, contain only lowercase letters, numbers, and hyphens, and be a maximum length of 63 characters. To enable support for Tanzu Application Engine, the cluster group you specify must be enabled for Tanzu Application Engine.

8. Select your configuration options.

9. Select the type of cluster that you want to create.

   The primary difference between the two is that the highly available cluster is deployed with multiple control plane nodes.

10. (Optional) add a description and label. Creating one or more labels that help you identify the cluster makes it easier to create an Availability Target on a cluster. For more information, see Use Availability Targets.

11. Click Next.

12. Configure the control plane.
13. Configure node pools.
14. After finishing configuring your cluster, click Create.
