[rdo-list] Heads up: Ceph Luminous (next LTS) is in release candidate

[Fox, Kevin M]

We were concerned the rdo packages had linked against the ceph libs and might break if a different version was slid in.
In discussions on irc, it seems like we were mistaken and everythings done through python modules provided by the various ceph versions. So shouldn't run into any issues.

I'm not an expert on the best way to tweak the containers for a newer version of ceph. So someone else might be better at answering. But I think template overrides are the way to go:

Thanks,
Kevin

hi Kevin,

for these same reasons tripleo stayed on jewel as well, but we'd like to
investigate the effort necessary for the switch.

CentOS can ship multiple versions of Ceph for the same OS version, it
provides two already centos-release-ceph-hammer and
centos-release-ceph-jewel; I believe -luminous can be added to that list.

Then, to consume it in tripleo, in cae kolla remains on jewel, would you
suggest use a build override to point kolla build to the luminous repos?
Are there drawbacks you can think of?

Thanks!
