question:

Having trouble deploying pods

# helm install chart.tgz
Error: Could not get apiVersions from Kubernetes: unable to retrieve the complete list of server APIs: metrics.k8s.io/v1beta1: the server is currently unable to handle the request

Solution:

Find the offending apiservice and delete it.

//View the problematic apiservice
# kubectl get apiservice
