Identify all clusterrolebindings to the cluster-admin role. Check if they are used and
|
|
if they need this role or if they could use a role with fewer privileges.

Where possible, first bind users to a lower privileged role and then remove the

|
clusterrolebinding to the cluster-admin role :

kubectl delete clusterrolebinding [name]
