Jie Yu commented on MESOS-5544:
-------------------------------
Systemd might still be problematic (esp. the delegate part).
Patches are needed currently around cgroups. See my branch.

> Project: Mesos
> Issue Type: Improvement
> Reporter: Jie Yu
>
> Currently, this does not work if one tries to use Mesos containerizer.
> The main problem is that we want to make sure the executor is not killed when
> agent crashes. So we have to use --pid=host so that the agent is in the host
> pid namespace.
> But that is not sufficient, Docker daemon will put agent into all cgroups
> available on the host. We need to make sure we migrate the executor pid out
> of those cgroups so that when agent crashes, executors are not killed.
> Also, when start the agent container, volumes need to be setup properly so
> that any mounts under agent's work_dir will be propagate back to the host
> mount table. This is to make sure we can recover those mounts after agent
> restarts. This is also true for those mounts that are needed by some isolator
> (e.g., network/cni isolator).
