Add Hosts to a Supervisor Cluster

As a vSphere administrator, you might need to scale out the Supervisor Cluster to run more workloads. To add capacity to a cluster, you can add ESXi hosts to the cluster thats uses a single vSphere Lifecycle Manager image.

When you add a host to the Supervisor Cluster that is configured with NSX, vSphere Lifecycle Manager installs the Spherelet VIB and the image on the host. After it is installed, vSphere with Tanzu configures the Spherelet process on the newly added host, which allows running containers natively on ESXi.

Prerequisites

• Obtain the user name and password of the root user account for the host.
• Verify that hosts behind a firewall might communicate with the vCenter Server.

Procedure

1. From the vSphere Client menu, select Workload Management.
2. Right-click the data center, cluster, or folder and select Add Host.
3. Enter the IP address or the name of the host and click Next.
4. Enter the administrator credentials and click Next.
5. Review the host summary and click Next.
6. Assign a license to the host and click Finish.
7. In the Add Host wizard, click Next.
8. Review the summary and click Finish.
   Note: If a host is part of the same data center, you can move it into the Supervisor Cluster. To move the host, put it in maintenance mode and drag it into the cluster.
