I can't find documentation on how to create user group on Kubernetes with yaml file. I'd like gather some authenticated users in group using their e-mail accounts.
I'd like to write in yaml something like :
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: ""Groups are determined by the configured authentication method. See https://kubernetes.io/docs/admin/authentication/ for details about how each authenticator determines the group membership of the authenticated user.
