How to check a feature-gate state in GKE

How to check a feature-gate state in GKE. The closes thing I found was doing:

kubectl cluster-info dump | grep feature-gate

but this only shows the flags of the nodes, not the master. Are they the same?

The reason I'm asking is the following: It's not very clear if CustomResourcesSubresources feature-gate is now beta or alpha and enabled by default or not. I’m confused as the PR here ( https://github.com/kubernetes/kubernetes/issues/62786 ) seems like it is beta since 1.11, but the documentation states ( https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/ ) that it’s still alpha and disabled by default (edited)

I use this:

kubectl get --raw /metrics | grep kubernetes_feature_enabled

(Grabbed it some time ago from here: https://cloud.google.com/kubernetes-engine/docs/concepts/feature-gates#check-feature-gate-state)

Works fine for all the k8s cluster flavours I manage (including EKS and the ones set up via kubeadm), not just GKE. :)

Masters are the same except it are managed by Google. The links you posted are Kubernetes specific.

Since there is no direct way to check for feature-gate states other than the method you shown, I went ahead and created a feature request to better handle that situation. You may also add further information in the thread.
