-----------------------------------
Summary: Support --revocable_cpu_low_priority flag for docker
containerizer
Key: MESOS-6338
URL: https://issues.apache.org/jira/browse/MESOS-6338
Project: Mesos
Issue Type: Improvement
Components: containerization
Reporter: Kunal Thakar
The mesos containerizer supports setting lower shares for revocable tasks by
passing --revocable_cpu_low_priority to the mesos agent. This flag is only
supported for mesos containerizer, but I don't see a reason why the behavior
can't be replicated for the docker containerizer.
On setting the flag, CPU shares assigned to revocable tasks are lower than
normal tasks
(https://github.com/apache/mesos/blob/master/src/slave/containerizer/mesos/isolators/cgroups/subsystems/cpu.cpp#L83).
This does not happen in the docker containerizer
(https://github.com/apache/mesos/blob/master/src/slave/containerizer/docker.cpp#L1517),
but it can be easily replicated there.
I can send a patch if this is acceptable.
