<p>I can't find documentation on how to create user group on Kubernetes with <code>yaml</code> file. I'd like gather some authenticated users in group using their e-mail accounts.</p>

<p>I'd like to write in <code>yaml</code> something like :</p>

<pre><code> kind: GoupBinding
 apiVersion: rbac.authorization.k8s.io/v1beta1
 metadata:
   name: "frontend-developers"
   namespace: development
subjects:
- kind: User
  name: a@xyz.com,vv@xyz.com
  apiGroup: ""
</code></pre>

<p>Groups are determined by the configured authentication method. See <a href="https://kubernetes.io/docs/reference/access-authn-authz/authentication/" rel="nofollow noreferrer">https://kubernetes.io/docs/reference/access-authn-authz/authentication/</a> for details about how each authenticator determines the group membership of the authenticated user.</p>
