LXC Container Support
Hello folks,
I've been Googling Mesos container support a bit recently, I see support
for Mesos(AppC) and Docker in the latest versions.
I'm looking to add LXC/LXD support, POC initially then hopefully bake it
into some Mesos libraries. From what I can tell Mesos doesn't have hooks
for LXC in the new container setup and also the External Shim that was
underdevelopment is Deprecated. Sound roughly accurate so far?
If so, would extending the Unified Containerizer be the correct way to go
about adding LXC/LXD support? (
http://mesos.apache.org/documentation/latest/container-image/)
Thanks
Tom

Hi Tom,
Your description of the current state of art is on point.
Regarding support for LXC/LXD, what exactly does it mean? Is there an image
spec for those that you want Mesos to support? What's your use case?
Thanks,

Everyone appears asleep on IRC so for a non real time response:
If I were looking to replicate the docker calls but for LXC, I'd be
updating stuff in the containerizer package right? Not the top level appc
and docker packages.

Thanks

Also just as an aside, being able to run system containers and not
precanned Docker applications would seem to certainly be a missing feature
that Mesos could benefit from, as it would allow sysadmins to spin up
vanilla Ubuntu, Centos, Debian etc images without doing something funky
like using the Docker image and tailing /dev/null. :)

Re: LXC Container Support
Posted by Tom Barber <to...@analytical-labs.com>.
Thanks guys. I do a lot of work with the juju ecosystem and lxc containers
to deploy workloads with that, for example multi node big top clusters etc.
It's far more flexible using LXC system containers than pre configured app
containers. This works on cloud and bare metal but I'd also like to be able
to deploy containers to Mesos using the same technology stack.
Cheers

Yup. External containerizer has been deprecated and removed. The direction
is to maintain only one containerizer in the future, and make that
containerizer better and supports various containerization requests.
If so, would extending the Unified Containerizer be the correct way to go
> about adding LXC/LXD support?
Yes, I would prefer exploring this direction. But even before that, it
would be nice to understand the motivation for using lxd. I'd prefer we
find out the feature gap and augment unified containerizer to fill the gap.
