<p class="MsoNormal"><span style="color:#1F497D">It looks like for 5.0.x you need to be cautious about is all the deprecated features in 4 that were removed in 5. It would not surprise me if we were still using some of those deprecated parts.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Puppet 5 also uses a newer ruby. We ship ruby 2.0 now. The notes for 5.0 indicate ruby 2.4, which is extra work and can take a while if existing ruby code needs to be changed.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Puppet 5 also claims to have hiera 5 built in. I don’t know what that means, we ship hiera 1.3.4 separarately, so there may be packaging concerns there as well.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Yan, thank you for making this very clear.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">As I read this, the puppet modules we use for the openstack clients are several releases old and the update to the Train version would be painful, er I mean lots of fun.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I think we need some input from the broader community.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">What are the costs / risks of upgrading to puppet 5.0?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Should we try to upgrade the client puppet modules ourselves (and contribute the changes upstream)? Or is there a better long way we should launch these clients, e.g. should we just write Ansible installers
for them?<o:p></o:p></span></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m now trying to upgrade the openstack clients installed on StarlingX to Train version.<o:p></o:p></p>
<p class="MsoNormal">Currently I see the clients are Stein version, but the puppet packages (for those modules that we need to config on StarlingX host) are still old versions. [See the list below.]<o:p></o:p></p>
<p class="MsoNormal">But for Train, I met a problem when I wanted to upgrade python-openstackclient/keystone to Train (4.0.0), the old puppet packages cannot work with Train clients and failed when running puppet-manifest-apply.sh.<o:p></o:p></p>
<p class="MsoNormal">See from Stein keystone log, some of the deprecated cmds and options are planned to be removed in Train.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If we want to make Train clients work, we may need to do the following steps:<o:p></o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoNormal" style="mso-list:l0 level1 lfo1">Upgrade puppet itself (required 5.x by Train)<o:p></o:p></li><li class="MsoNormal" style="mso-list:l0 level1 lfo1">Upgrade all the OpenStack related puppet packages accordingly, and update StarlingX patches.<o:p></o:p></li><li class="MsoNormal" style="mso-list:l0 level1 lfo1">If flock puppet pkgs are based on puppet 4.8.2, we also need to upgrade our code.<o:p></o:p></li><li class="MsoNormal" style="mso-list:l0 level1 lfo1">If other puppet pkgs are based on puppet 4.8.2, we also need to upgrade those pkgs.<o:p></o:p></li></ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So is it possible that we keep on using Stein clients with limited test now (need test with Train images, but suppose old functions should still work)?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here’s the list of the puppet packages and StarlingX patches (for Stein it should be 14.1.0 – 14.4.0, and for Train 15.0.0 – 15.4.0):<o:p></o:p></p>
