Shuai Lin commented on MESOS-2724:
----------------------------------
Thanks for the quick reply [~tnachen]!
I'm not that familiar with {{DockerContainerizer}} and {{MesosContainerizer}}
yet. However, I would rather prefer a more generic way to do custom actions
when a container is launched. Because even if all [~baotiao] wants is to change
are {{cfs_period_us}} and {{blkio}} limit, it's very likely that different
containers may need different settings, e.g. based on the user who launched the
task, or the label of the task.
Actually I'm thinking if one only need to apply the same set of cgroups
settings to all docker containers, he can always do that by polling docker
daemon for the list of running containers from time to time, and apply cgroups
settings for those new containers that has been created since the last poll:
there is no work need to do on mesos side at all.
But if he wants different cgroups settings for different containers (e.g. based
on the user who launches the task), then it requires application level logic
that is external to mesos, and should be triggered by a hook.

> gWe use mesos + marathon to build our Paas platform. We meet a problem
> We want to execute some command after the docker container started. such as
