cgroup usage must be confirmed in Docker Enterprise.
Description
Discussion Text
It is possible to attach to a particular cgroup on container run. Confirming cgroup usage would ensure that containers are running under defined cgroups.
System administrators typically define cgroups under which containers are supposed to run. Even if cgroups are not explicitly defined by the system administrators, containers run under docker cgroup by default. At run-time, it is possible to attach to a different cgroup other than the one that was expected to be used. This usage should be monitored and confirmed. By attaching to a different cgroup than the one that is expected, excess permissions and resources might be granted to the container and thus, can prove to be unsafe.
By default, containers run under docker cgroup.
