Hi Karanbir,
I'm sorry I missed the office hours hangout, but I listened back over
most of the discussion.
I've been thinking a bit about RDO, CentOS and the Cloud SIG and wanted
to drop some thoughts here in case it helps the discussion.
The thing is - I'm hugely excited about the changes happening around
CentOS and think there are great opportunities here. That said, I want
to be realistic about what's likely to happen around CentOS and RDO in
the medium term.
So, what does the RDO maintenance team care about?
- our focus is making a usable distro of vanilla OpenStack available
on EL distros and persuade OpenStack users that EL is the best
choice for running OpenStack than Ubuntu - i.e. we're talking about
people who know they want (or want to try) OpenStack and we want to
persuade them to use EL
- our instinct would be to show EL as rock-solid in terms of
performance and stability even if that's at the expense of newer
features. To me, that means replacing as little of the base distro
as possible, especially the hypervisor bits. I'd be keen to make
zero or very few modifications to the EL kernel, qemu and libvirt.
- to deliver RDO to date, we've been getting by using Fedora
infrastructure but it would probably be a big improvement if we
could switch over to CentOS infrastructure - e.g. koji, git, yum
repos, etc.
- obviously there are other projects which aren't in the base OS that
can be very useful to RDO users - e.g. Open vSwitch, Open Daylight,
GlusterFS, Ceph, Docker, Xen, etc. If they were available through
CentOS, we'd love to make it really easy for RDO users to use them.
- as an opt-in "preview" variant of RDO on CentOS, it would be really
cool to have newer base OS features available for people to
experiment with - I'd expect this to be fairly rapidly moving and
not recommended for real-world use, though. I could definitely
imagine the other IaaS projects having a similar need and some
shared maintenance happening there.
- the difficulty with both of these is that - despite everyone's best
intentions - RDO maintainers aren't necessarily going to be able to
make a tonne of time to help out with either of them. Keeping up
with OpenStack is enough of a challenge in itself.
- I don't imagine RDO folks being terrifically interested in doing
work to make OpenStack co-exist on the same system or in the same
distro with other IaaS project, just because it's a tonne of work
and hard to imagine it helping users all that much. The "choose your
own adventure" LiveCD idea does sound cool, but even that doesn't
necessarily require all projects to live together in the same repo.
So, to summarize - the main things of interest to RDO folks would
probably be:
- using CentOS koji, git and yum repos to build, maintain and deliver
RDO
- builds of CentOS images for RDO users to run in their guests
- collaboration with other projects to experiment with and learn
about e.g. packaging with SCLs (either packaging the apps
themselves as SCLs, or just their dependency stacks)
- re-using any work other SIGs do around packaging and maintenance of
other projects which will be useful to RDO users
- collaboration around the maintenance of a preview/experimental
variant which includes newer base OS features which are particularly
interesting for IaaS projects
I guess I'm curious whether other projects which have an interest in the
Cloud SIG share a similar perspective?
For example, in the office hours chat I think there was an assumption
that all of our projects need newer kernels, libvirt and qemu whereas
I'd be worried about exposing RDO users to potential instability by
doing that.
Thanks in advance,
Mark.
