GKE - "Migrate to updated APIs" errors

I have a similar problem to this post: GKE - "Migrate to updated APIs" but cannot find any resources for it

The GKE cluster says that the gkebackup/agent calls the /apis/policy/v1beta1/podsecuritypolicies API.

Migrate to supported APIs error image

I am indeed using a protectedapplication to backup certain configmaps from the cluster, but as far as I know this uses the gkebackup.gke.io/v1alpha2 API.

> kubectl get --raw /apis/policy/v1beta1/podsecuritypolicies | jq

Solution

  • Similar to how I answered the aftermentioned post. There is a possibility something in the cluster is calling certain API's even if you don't have objects in the cluster created under these API's.

    So basically just ignore it!
