Tom Arnfeld commented on MESOS-1524:
------------------------------------
This sounds really great. I think implementing this would be easier now since
the refactor of the Containerizer classes...?
I'd vote for #2 since i'd guess it's easier (than #3) to support launching
containers on a remote host (the {{-H}} argument in #1). This is really quite
useful for development, when running Mesos on a Mac and having docker running
inside VM, for example.
For me though, this does raise a question. From what I gathered the main idea
behind the external containerizer was to allow not just pluggability (the c++
classes _could_ be made "pluggable") but also ease of use for developers and
users to get involved. How do you envisage this happening with other isolation
mechanisms? Will the external containerizer act as a way of proving the
concept, and eventually support for that containerizer would be implemented
into Mesos itself?

> Key: MESOS-1524
> URL: https://issues.apache.org/jira/browse/MESOS-1524
> Project: Mesos
> Issue Type: Epic
> Reporter: Tobi Knaup
> Assignee: Benjamin Hindman
>
> There have been two projects to add Docker support to Mesos, first via an
> executor, and more recently via an external containerizer written in Python -
> Deimos: https://github.com/mesosphere/deimos
> We've got a lot of feedback from folks who use Docker and Mesos, and the main
> wish was to make Docker a first class citizen in Mesos instead of a plugin
> that needs to be installed separately. Mesos has been using Linux containers
> for a long time, first via LXC, then via cgroups, and now also via the
> external containerizer. For a long time it wasn't clear what the winning
> technology would be, but with Docker becoming the de-facto standard for
> handling containers I think Mesos should make it a first class citizen and
> part of core.
> Let's use this JIRA to track wishes/feedback on the implementation.
