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)
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.
