             Summary: Docker containerizer ignores capability requests
                 Key: MESOS-7156
                 URL: https://issues.apache.org/jira/browse/MESOS-7156
             Project: Mesos
          Issue Type: Bug
          Components: containerization, documentation
    Affects Versions: 1.1.0
         Environment: Ubuntu 16.04
            Reporter: Bruce Merry
            Priority: Minor


I'm trying to set a capability (SYS_NICE) by populating the linux_info.capability_info.capabilities field in a ContainerInfo, while using the Docker containerizer. I was expecting this to turn into a `--cap-add` argument passed to Docker, but in fact nothing happens. I also grepped the source of Mesos HEAD and there doesn't seem to be any code to pass --cap-add.

Maybe this is intended, but I couldn't find anything to indicate this in the documentation or in mesos.proto, and the placement of linux_info in ContainerInfo rather than in MesosInfo led me to expect that it would be supported independently of the containerizer.
