Niklas Quarfot Nielsen commented on MESOS-1094:
-----------------------------------------------
I see - should the command executor prepend mesos-nsexec to the command (in the
case where it is supported)? There would need to be a way to check support
before calling I suppose?
how far have you gotten with nsexec?
> Introduce pid namespace abstraction to subprocess

> Key: MESOS-1094
> URL: https://issues.apache.org/jira/browse/MESOS-1094
> Project: Mesos
> Issue Type: Improvement
> Reporter: Niklas Quarfot Nielsen
> Assignee: Niklas Quarfot Nielsen
>
> Introducing PID namespacing could simplify signal escalation and process
> control in for example the command executor and pluggable containerizer.
> Along the lines of the Fork Exec abstraction in stout, I suggest that we add
> an abstraction for Linux namespaces.
> LinuxNamespace(PID /* | IPC | mount | ...*/, Fork(Exec("sleep 10"))
> It would be guarded or add convenience methods to ensure system support, for
> example bool LinuxNamespace::supports(PID /* | IPC | ... */) or simply let
> the namespace fall back to regular fork/exec.
> I have a proof-of-concept version of the command executor which use PID
> namespaces (in combination with delay/escalation), and it feels like details
> around stack allocation and management could be captured in a new abstraction
> and make it a neat and nice subsystem to use.
