After deploying the VMware Tanzu Kubernetes Grid workload cluster, you can export the<KUBECONFIG_FILE> from the cluster by running the following command from the VMware Tanzu Kubernetes Grid deployment host.

tanzu cluster kubeconfig get <CLUSTER_NAME> --admin --export-file <KUBECONFIG_FILE_NAME>

For more information, see VMware Tanzu Kubernetes Grid documentation. You can then copy the exported file <KUBECONFIG_FILE> to the VMware Telco Cloud Service Assurance deployment host under the home directory /home/<user>/.kube and use this location for the KUBECONFIG property in the values-user-overrides.yaml file used for deployment.
