Subject [jira] [Created] (MESOS-8327) Add container-specific CGroup FS mounts under /sys/fs/cgroup/* to Mesos containers
Date Wed, 13 Dec 2017 06:38:00 GMT
Jason Lai created MESOS-8327:
--------------------------------

             Summary: Add container-specific CGroup FS mounts under /sys/fs/cgroup/* to Mesos
containers
                 Key: MESOS-8327
                 URL: https://issues.apache.org/jira/browse/MESOS-8327
             Project: Mesos
          Issue Type: Task
          Components: containerization
            Reporter: Jason Lai
            Assignee: Jason Lai


Containers launched with Unified Containerizer do not include container-specific CGroup FS
mounts under {{/sys/fs/cgroup}}, which are created by default by Docker (usually readonly
for unprivileged containers). Let's honor the same convention for Mesos containers.

For example, this is needed by Uber's [{{automaxprocs}}|https://github.com/uber-go/automaxprocs]
patch for Go programs, which amends {{GOMAXPROCS}} per CPU quota and requires access to the
CPU cgroup subsystem.
