I have a question about groups in k8s. I have not seen group creation in any of the lectures so far. How is it done? Or are we limited to built in groups like system:… ?

Mohamed Ayman:
what u re taking about? Is it a group in the role binding or what?

#3

kmkale:
I want to know how to create custom groups

#4

Mohamed Ayman:
Still not clear for me

#5

kmkale:
That means I do not have enough knowledge to explain my question. I will come back to it after some more study. Thanks.

OK, so in this example from the RBAC practice test,

controlplane $ k -n kube-system describe <http://rolebindings.rbac.authorization.k8s.io|rolebindings.rbac.authorization.k8s.io> kube-proxy 
Name:         kube-proxy
Labels:       &lt;none&gt;
Annotations:  &lt;none&gt;
Role:
  Kind:  Role
  Name:  kube-proxy
Subjects:
  Kind   Name                                             Namespace
  ----   ----                                             ---------
  Group  system:bootstrappers:kubeadm:default-node-token

The Subjects refer to a kind Group. Which in this instance is system:bootstrappers:kubeadm:default-node-token

If I want to create a group called custom:team-1 how do I do that?
