Open Stack

Ahoy infra folks,

So TripleO/RDO is currently working on our transition from python2 to
python3 and would like to stabilize on Fedora 28 during the Stein
cycle until a newer version of CentOS comes out with proper python3
support.  So we would like to ask if it would be possible to keep
Fedora 28 around until Fedora 30 comes out + 1 month. This is the
published maintenance schedule[0].  Based on current assumptions this
would mean that Fedora 28 would be EOL around June, 2019.  Ideally our
plan would be to migrate off of the Fedora 28 jobs before it is
officially EOL.

We are aware that release schedules can change and are definitely
keeping an eye on that in terms of Fedora.  The next release of Fedora
29 is slated to include python 3.7 which may be too new for
OpenStack[1] so we would like to start work on the 3.6 that is
available from 28.  We've already started working on getting packaging
working for Fedora 28. Our first goal is to get the various services
and deployments working under 3.6. Once that has been tackled, an
upgrade to Fedora 29 or newer will likely be less work than trying to
go from 2.7 to 3.7.

We would like to use fedora 28 rather than something like python3 from
EPEL7 in that it would be a better representation of a Red Hat based
OS without any python2 support.  We're looking to uncover the python 2
to 3 transition issues with TripleO as well as starting to pull in
other newer dependencies.

Thanks,
-Alex
