Description
This check ensures that the container in the DaemonSet has RBAC included in the argument authorization mode.
Usage
Run the control in your terminal:
powerpipe control run kubernetes_compliance.control.daemonset_container_argument_authorization_mode_rbac
Snapshot and share results via Turbot Pipes:
powerpipe loginpowerpipe control run kubernetes_compliance.control.daemonset_container_argument_authorization_mode_rbac --share
SQL
This control uses a named query:
