You need an Ubuntu 14.04 server with nothing else running, but LXC.
100% of the real work gets done via Centos containers.It works
perfectly and it is rock solid.
The only thing on top is the latest available kernel
3.19.0-33-generic. Yo never have to login or otherwise touch Ubuntu,
it becomes a simple container host. I have literally hundreds of
containers with this architecture. For some reason, the fact that
Ubuntu does not use systemd, makes it stable and almost perfect. I
cannot explain it, but it becomes like the engine of a Mercedes, you
know it is there, but you don't need to see it, it becomes invisible.
I could never use Fedora as a good container host, for you end up
having to compile your own RPMs and it fails often. They just don't
take LXC seriously, or they would be at the same level of Ubuntu.
Our software runs in CentOS containers which in turn run under CentOS
based hypervisors, working together in a cluster. Even switching out our
servers to run Ubuntu instead of CentOS would be a non-trivial process.
We'd need to support an upgrade path for example where we would upgrade
our customers' servers, swapping out CentOS in-place in favor or Ubuntu.
Doable but not something we really have the bandwidth to take on and
keep with our release schedule.
