CLUSTER_CONFIG: Specifies the
admin cluster configuration
file or the user cluster configuration
file, depending on which cluster you are updating.That cluster configuration file includes a reference
to the vCenter credentials that you want to deploy to your cluster.
ADMIN_CLUSTER_KUBECONFIG: Specifies the
kubeconfig file of the admin cluster.
Example: kubeconfig
For updating credentials for the admin cluster, you must also include the
--admin-cluster flag.
--admin-cluster: Required flag if you are
deploying changes to the admin cluster. Exclude this flag when deploying
changes to a user cluster.
Result: The changed vCenter credentials are immediately validated against
the server and a confirmation is output to the terminal:
"vsphere credentials updated successfully". If the new credentials fail to
log in to the vCenter server, you can edit the username and password in
the credentials file and redeploy your changes.

Update F5 BIG-IP credentials for an admin cluster or a user cluster
Update the F5 BIG-IP credentials in the F5 web interface.
On your admin workstation, use the following steps to update the F5 BIG-IP
credentials for an admin cluster or a user cluster.
Edit your F5 credentials file to change the credentials.
Update the F5 BIG-IP credentials for your cluster:

The [admin cluster configuration file](/anthos/clusters/docs/on-prem/1.9/how-to/admin-cluster-configuration-file#vcenter-credentials-fileref-path-field) contains a reference to a credentials file, as does each [user cluster configuration file](/anthos/clusters/docs/on-prem/1.9/how-to/user-cluster-configuration-file#vcenter-credentials-fileref-path-field). These references can be different for each cluster.\n\nUse the following steps to update the vCenter credentials on a cluster:\n\n1.
