<p class="xmsonormal">Hello All,<o:p></o:p></p>
<p class="xmsonormal"> <o:p></o:p></p>
<p class="xmsonormal">We are working on FM containerization (FM panel in open stack dashboard and backend pod service(fault)).<o:p></o:p></p>
<p class="xmsonormal">As part of this activity, we are doing stx-horizon docker build. Which will include components from flock (for fm calls). As a reference example, please refer to this
<a href="https://review.opendev.org/c/starlingx/upstream/+/661423/4/openstack/python-horizon/centos/stx-horizon.stable_docker_image">
patch</a>.<o:p></o:p></p>
<p class="xmsonormal">The front panel would be calling flock components fmclient, cgtsclient, distributedcloud etc.<o:p></o:p></p>
<p class="xmsonormal">These components are python2 build. For FM panel to work we need migration of these components (seeing lot of dependency issues) from python2 to python3 on master branch.<o:p></o:p></p>
<p class="xmsonormal"> <o:p></o:p></p>
<p class="xmsonormal">Yesterday(9-Dec-2020) in non-openstack distro meeting, the discussion was flock python2 dependent components cannot be migrated in master branch and will done in centos8 migration branch/stream.<o:p></o:p></p>
<p class="xmsonormal"> <o:p></o:p></p>
<p class="xmsonormal">So, I request for clarity/decision from community on this blocker for FM containerization.<o:p></o:p></p>
<p class="xmsonormal"> <o:p></o:p></p>
<p class="xmsonormal">Earlier in stx-3.0(stein’s openstack) as in above link, these component were part of stx-horizon docker build. But these were removed(as per patch below) as part of stx-4.0 migration (stein
