Obtain a list of the principals who have access to the cluster-admin role by reviewing the clusterrolebinding output for each role binding that has access to the cluster-admin role. kubectl get clusterrolebindings -o=custom-columns=NAME:.metadata.name,ROLE:.roleRef.name,SUBJECT:.subjects[*].name Review each principal listed and ensure that cluster-admin privilege is required for it.

Nasıl düzeltilir

Düzeltme yöntemi: Kılavuz veya altyapı yaması

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]
