Looking for suggestions on MESOS-2724
Hi all,
I'm working on https://issues.apache.org/jira/browse/MESOS-2724 (Support
running custom commands on slaves when launcing a docker container), and
would like to get suggestions from you.
Please check my latest comment here

Hi Shuai,
Thanks for your interest in doing this!
The DockerContainerizer *might* have support for Isolators but it's still
in discussion mode how/what that will look like as it's largely depending
on how the Docker engine evolves. Current state of the engine have very
limited ability to add custom isolation logic.
I'll leave more comments on the JIRA.

I prefer a executorLaunched hook, if it can be triggered with enough
details of the container as stated in this comment <http://I would rather
prefer a executorLaunched if it can be triggered with details of enough
information of the container. As>.
About my timeframe: I myself doesn't require this feature in my work, so I
have no specific time requirement on this.

It sounds like we have two options to support your use-case:
1) Introduce a executorLaunched hook
2) Wait until DockerContainerizer supports isolators
(1) Will probably be the quickest, but also a fairly unclean one - as the
slave doesn't have access to the executor pids directly.
(2) is probably the right way, but takes more effort. What is your current
timeframe?
