Phương pháp kiểm tra: Xem xét thủ công
To check which role bindings have the ability to clone across namespaces, use the following command where to list all the rolebinding and verify which one has a ClusterRole which enables it to operate on data volumes and have bound a service account in another namespace . Ensure that the destination namespace is a desired one. $ oc get rolebinding - n <source - namespace> <allow - clone - to - user> - oyaml Output will be in the following format: apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: <role - binding - name> namespace: <source namespace> subjects: - kind: ServiceAccount name: default namespace: <destination namespace> roleRef: kind: ClusterRole name: ...
