Sam (the guy who implemented docker support in Nova) is now adding docker support to Heat, the Openstack alternative to Cloudformation. It looks really awesome :) <a href="http://www.mail-archive.com/openstack-dev@lists.openstack.org/msg06415.html" rel="nofollow">http://www.mail-archive.com/openstack-dev@lists.openstack.or...</a>
I am yet to understand what docker brings to nova, what the existing lxc driver couldn't do.. It <i>seems</i> like an abstraction layer which is hidden by nova.. therefore no new gain?
