Yan Xu updated MESOS-3308:
--------------------------
Labels: twitter (was: )
> Define the container rootfs directories within the slave work_dir.
> ------------------------------------------------------------------

> Key: MESOS-3308
> URL: https://issues.apache.org/jira/browse/MESOS-3308
> Project: Mesos
> Issue Type: Task
> Reporter: Yan Xu
> Labels: twitter
>
> A few motivations:
> 1) Given the design in MESOS-3004 it became apparent that we need to support
> multiple images in a container and these images can be of different image
> types. (There are no sufficient reasons or major obstacles that force us not
> to allow it and it obviously gives the users more flexibility).
> 2) Also, even though we currently allow only one backend for each
> provisioner, when we update a running slave there can be multiple backends
> left in each container that we need to launch tasks with, or at least
> recover. We should evaluate in the future whether to support multiple
> backends and choose among them dynamically based on image characteristics.
> 3) Since the rootfs' lifecycle tie with the running containers and should be
> cleaned up after containers die, it fits into the pattern of {{word_dir}} and
> we can manage them inside the work dir without needing to ask the operator to
> specify more flags.
