Timothy Chen commented on MESOS-2183:
-------------------------------------
Hi [~jaybuff], nice timing as I'm currently working on patches about the docker
containerizer launching in a docker container itself.
However I'm more focused on launching Tasks then Executors, so will have to
look into this much later.
> docker containerizer doesn't work when mesos-slave is running in a container

> Key: MESOS-2183
> URL: https://issues.apache.org/jira/browse/MESOS-2183
> Project: Mesos
> Issue Type: Bug
> Components: containerization
> Reporter: Jay Buffington
>
> I've started running the mesos-slave process itself inside a docker
> container. I bind mount in the dockerd socket, so there is only one docker
> daemon running on the system.
> The mesos-slave process uses "docker run" to start an executor in another,
> sibling, container. It asks "docker inspect" what the pid of the executor
> running in the container is. Since the mesos-slave process is in its own pid
> namespace, it cannot see the pid for the executor in /proc. Therefore, it
> thinks the executor died and it does a docker kill.
> It looks like the executor pid is also used to determine what port the
> executor is listening on.
