title: How to check a feature-gate state in GKE
body: <p>How to check a feature-gate state in GKE. The closes thing I found was doing:</p>
  
  <p><code>kubectl cluster-info dump | grep feature-gate</code></p>
  
  <p>but this only shows the flags of the nodes, not the master. Are they the same?</p>
  
  <p>The reason I'm asking is the following: It's not very clear if <code>CustomResourcesSubresources</code> feature-gate is now <strong>beta</strong> or <strong>alpha</strong> and enabled by default or not. I’m confused as the PR here ( <a href="https://github.com/kubernetes/kubernetes/issues/62786" rel="noreferrer">https://github.com/kubernetes/kubernetes/issues/62786</a> ) seems like it is <em>beta since 1.11</em>, but the documentation states ( <a href="https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/" rel="noreferrer">https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/</a> ) that it’s still <em>alpha and disabled by default</em> (edited) </p>
