I missed that session in Atlanta but sounds like what you're talking about is a pretty standard approach on OpenStack. I think it's a good way to go. I've heard little overhead is lost by running the container host on a VM vs. bare metal, and the advantage is better tenant isolation (so if for some reason the container host is compromised, it's not as big a deal as an entire hypervisor being compromised.)
You also gain a relatively easy way to tie in cinder for additional block storage. -Christopher On Thu, Feb 5, 2015 at 4:00 AM, Zeeshan Ali Shah <[email protected]> wrote: > Thanks Christopher for details response, > > What if we take this path > https://www.openstack.org/summit/openstack-summit-atlanta-2014/session-videos/presentation/automating-service-orchestration-with-docker-and-coreos > > that is have core OS images and use them to launch docker images over it. > > any comment ? > > > /Zee > > On Wed, Feb 4, 2015 at 4:55 PM, Christopher Aedo <[email protected]> wrote: >> >> The Nova-Docker driver is available here, and allows Nova to address a >> Docker host natively: >> https://github.com/stackforge/nova-docker >> There are some very recent commits, and it's being actively developed. >> >> The Kolla work (https://github.com/stackforge/kolla) has details on >> deploying Docker images via Heat templates (for the Triple-O project - >> but can easily be extended to Docker-specific stuff). >> >> Lars' blog post from last summer goes over the Docker plugin for Heat: >> http://blog.oddbit.com/2014/08/30/docker-plugin-for-openstack-he/ >> >> The Magnum project (https://wiki.openstack.org/wiki/Magnum) is young, >> but making fast progress.
