To update a Supervisor, including the Kubernetes version that the Supervisor is running and the infrastructure supporting Tanzu Kubernetes Grid clusters, including the Tanzu Kubernetes Grid 2.0, you perform a vSphere Namespaces update.

There is a version entity for vSphere with Tanzu. The version entity is a semantic version string in the form v1.21.1+vmware.2-vsc0.0.8-17610687, where the prefix is the Kubernetes version (v1.21.1) and the suffix is the vSphere Namespaces version (vsc0.0.8-17610687).

Prerequisites

Read the vSphere with Tanzurelease notes before you perform a vSphere Namespaces update.

To install the necessary binaries, upgrade the vCenter Server appliance and ESXi hosts to the supported version. See Upgrading the vCenter Server Appliance in the vCenter Server documentation.

Note: When you perform a vSphere Namespaces update, all provisioned Tanzu Kubernetes clusters must be in a running state. If a Tanzu Kubernetes is in a creating or deleting state, wait until the process finishes before updating a Supervisor, otherwise might not succeed.
Note: Updating a Supervisor will likely trigger a rolling update of the Tanzu Kubernetes clusters deployed there. See Updating TKG 2 Clusters on Supervisor.

Procedure

  1. Log in to the vCenter Server as a vSphere administrator.
  2. Select Menu > Workload Management.
  3. Select the Namespaces > Updates tab.
  4. Select the Available Version that you want to update to.
    For example, select the version v1.23.5+vmware.wcp.2-vsc0.1.1-20805373.
    Note: You must update incrementally. Do not skip updates, such as from 1.21 to 1.22. The path should be 1.21, 1.22, 1.23.
  5. Select one or more Supervisors to update.
  6. Click Apply Updates.
    You can use the Recent Tasks pane to monitor the status of the update
