<p class="MsoNormal"><span style="color:#1F497D">Shuicheng, thank you. I tend to agree with you that Option 2 is the way to go, but I have some questions that maybe you or someone else in the community can answer.<o:p></o:p></span></p>

Do we know how long it will take CentOS to produce the RPM on Train’s Keystone?<o:p></o:p></li></ul>

<p class="MsoNormal" style="margin-left:.5in">[shuicheng] I assume Host keystone (Stein) should have no communication with OpenStack(Train). Please correct me if it is wrong.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in">[shuicheng] We could do it. Option 1 is to use upstream keystone code directly.

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal">There is a task 36619 [0] “update keystone on the host from the SRPM” of story 2006544 “Integrate with OpenStack Train (master)”.<o:p></o:p></p>
<p class="MsoNormal">Due to Train is not released yet, and it will take sometime for CentOS to support Train and provide the SRPM.<o:p></o:p></p>
<p class="MsoNormal">We have two option as below. And I prefer Option 2, since host keystone is to serve flock service, not OpenStack service.<o:p></o:p></p>
<p class="MsoNormal">Please help provide your suggestion.<o:p></o:p></p>
<p class="MsoNormal">Thanks in advance.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Option 1:<o:p></o:p></p>
<p class="MsoNormal">To catch stx 3.0 release, we need switch SRPM to use upstream git directly.
<o:p></o:p></p>
<p class="MsoNormal">Advantage:<o:p></o:p></p>
<p class="MsoNormal">Host keystone will align with containerized keystone.<o:p></o:p></p>
<p class="MsoNormal">Disadvantage:<o:p></o:p></p>
<p class="MsoNormal">A few keystone related packages need switch from SRPM to git repository.<o:p></o:p></p>
<p class="MsoNormal">Other rpms may need be upgraded also if they have dependency on keystone.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Option 2:<o:p></o:p></p>
<p class="MsoNormal">We defer the upgrade task to stx 4.0, wait until SRPM is available in CentOS mirror.<o:p></o:p></p>
<p class="MsoNormal">Advantage:<o:p></o:p></p>
<p class="MsoNormal">Follow current design, and related packages could be upgraded easily together.<o:p></o:p></p>
<p class="MsoNormal">Disadvantage:<o:p></o:p></p>
<p class="MsoNormal">Host keystone will differ from containerized keystone.<o:p></o:p></p>
<p class="MsoNormal">Not sure when CentOS will provide SRPM for Train.<o:p></o:p></p>
