Question #: 83
Topic #: 4
Question #: 83
Topic #: 4
An administrator is upgrading an existing VMware vSphere Kubernetes Service (VKS) cluster and receives the following errors:
kubectl get nodes fails with memcache.go and "server is currently unable to handle the request" couldn't get resource list for stats.antrea.tanzu.vmware.com/v1alpha1 yaml: mapping values are not allowed in this context The administrator successfully updated the Supervisor, but an attempt to update the VKS cluster failed. Based on the scenario, what is the cause of the problem?

Suggested Answer: A Vote an answer
The errors described-specifically the memcache.go failure, the inability to fetch resource lists for Antrea, and the YAML context error-are classic symptoms of aConfiguration Context mismatch. In VCF 9.0, there are two distinct layers of API interaction: theSupervisor Cluster API(used for management tasks like creating clusters) and theGuest Cluster API(used for deploying workloads within the VKS).
When an administrator upgrades a Supervisor, the API endpoint or the available API groups may change. If the administrator attempts to run kubectl commands against a VKS cluster while their kubeconfig context is still pointing to the Supervisor (or vice versa), the client will encounter "mapping values" errors and "unable to handle request" errors because it is sending requests to an endpoint that does not recognize those specific resource definitions (like Antrea stats in the wrong context). To resolve this, the administrator must ensure they have switched to the correct context using kubectl config use-context <cluster-name> after the Supervisor update to ensure the local client is communicating with the correct API server and version of the Kubernetes binaries.
