# This is a sample policy to demonstrate configuring RBAC for managed clusters using admin and view-only roles
# This Policy considers that below groups needs to be pre-existing before the policy can be configured.
# Groups: acm-admins, ac-viewonly-users
# Group acm-admins to have admin access to all managed clusters
# Group ac-viewonly-users to have view-only access to all managed clusters
# ManagedclusterX refers to the name of any managed cluster
# This Policy Configures the following rbac model for the above scenario
# UsersGroups: acm-admins, ac-viewonly-users
# Rolebindings:
# acm-admins group has cluster-admin access to all managed clusters including the hub cluster
# ac-viewonly-users group has view-only access to all managed clusters including the hub cluster
