             Summary: Add support for per-containerizer resource enumeration
                 Key: MESOS-5256
                 URL: https://issues.apache.org/jira/browse/MESOS-5256
             Project: Mesos
          Issue Type: Task
          Components: isolation
            Reporter: Kevin Klues
            Assignee: Kevin Klues


Currently the top level containerizer includes a static function for enumerating the resources available on a given agent. Ideally, this functionality should be the responsibility of individual containerizers (and specifically the responsibility of each isolator used to control access to those resources).

Adding support for this will involve making the `Containerizer::resources()` function virtual instead of static and then implementing it on a per-containerizer basis.  We should consider providing a default to make this easier in cases where there is only really one good way of enumerating a given set of resources.
