Once you have performed a vSphere Namespace update and upgraded the Supervisor Cluster, update the vSphere Plugin for kubectl.
The most recent version of the vSphere Plugin for kubectl downloads and installs the Tanzu Kubernetes cluster root CA certificate in the Kubernetes secret named
TANZU-KUBERNETES-CLUSTER-NAME-ca. The plugin uses this certificate to populate the CA information in the corresponding cluster's certificate authority datastore.
To download and install the vSphere Plugin for kubectl, see Download and Install the Kubernetes CLI Tools for vSphere. For more information about the
TANZU-KUBERNETES-CLUSTER-NAME-ca secret, see Get Tanzu Kubernetes Cluster Secrets.
