Control: ReplicaSet containers argument kubelet read-only port should be set to 0
Description
This check ensures that the container in the ReplicaSet has argument kubelet read-only port set to 0.
Usage
Run the control in your terminal:
powerpipe control run kubernetes_compliance.control.replicaset_container_argument_kubelet_read_only_port_0Snapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe control run kubernetes_compliance.control.replicaset_container_argument_kubelet_read_only_port_0 --shareSQL
This control uses a named query:
