<p class="MsoNormal">> Hi there all-ye-operators,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> I am investigating how to help move godaddy from rpms to a
<o:p></o:p></p>
<p class="MsoNormal">> container-like solution (virtualenvs, lxc, or docker...) and a set of
<o:p></o:p></p>
<p class="MsoNormal">> questions that comes up is the following (and I would think that some
<o:p></o:p></p>
<p class="MsoNormal">> folks on this mailing list may have some useful insight into the answers):<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> * Have you done the transition?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are currently in the middle of the transition to a containerized deployment solution for Cray’s OpenStack-based System Management platform.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> * How did the transition go?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So far, so good.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> * Was/is kolla used or looked into? or something custom?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We evaluated both openstack-ansible and Kolla. Each has its advantages but Kolla won over thanks to its simplicity, speed of deployment and use of immutable containers. We’re also using Kolla’s ansible deployment tool.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> * How long did it take to do the transition from a package based
<o:p></o:p></p>
<p class="MsoNormal">> solution (with say puppet/chef being used to deploy these packages)?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For the first iteration we’re still using a package-based solution. This is largely because we have considerable infrastructure built up around this. We’re using OpenStack’s Anvil tool, which I know you are familiar with, Josh
<span style="font-family:Wingdings">J</span>.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Kolla supports installing from both packages and source, so we have the option of moving to source in future if it fits.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">> * Follow-up being how big was the team to do this?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There are 4 of us working on this project. The work involved is considerably more than for an operator because we are building a platform based on OpenStack with multiple deployment environments. We estimated about 6 man-months.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">><o:p> </o:p></p>
<p class="MsoNormal">> * What was the roll-out strategy to achieve the final container solution?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This will be difficult. As others have said, we expect to do this one service at a time, and will add considerable automation around it. Migrating stateful services such as the DB and nova-compute will need care.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
