<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I’ll start by answering the last questions: “</span><span style="font-size:11.0pt">Is that kind of deployment possible? If not possible, is this or could this be in the roadmap of the project?”<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">It’s been a while that we discussed the limitations of the user-friendliness of our inventory. So, yes it’s part of our long term road map, and we discussed it at the summit.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I don’t expect the inventory to be radically changed in this cycle.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">However…<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I think (never tried) it’s technically possible to do what you are asking for. But it’s gonna involve a few hacks in the inventory.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">This is worth a complete conversation on the channel, because it’s hard to fully understand your requirements with a brief email.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">Anyway, let me give you some hints…<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt"><o:p> </o:p></span></p>

</span></span></span><![endif]><span lang="EN-US" style="font-size:11.0pt">You could technically assign whatever IP you require in your compute/controller nodes, as long as they are properly ssh reachable from your deploy node.<o:p></o:p></span></p>

</span></span></span><![endif]><span lang="EN-US" style="font-size:11.0pt">I think you could define many cidr_networks, and change the ip_from_q per site (instead of having global_overrides, you’d have to define override per host/group of hosts)<o:p></o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-.25in;mso-list:l0 level1 lfo1"><![if !supportLists]><span lang="EN-US" style="font-size:11.0pt"><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">

</span></span></span><![endif]><span lang="EN-US" style="font-size:11.0pt">Please keep in mind that you most likely (depending on your multicast routing configuration?) won’t be able to use haproxy + keepalived co-located on your controller nodes, because we
are using multicast for VRRP. That means that if you have another load balancer, or are ready to configure keepalived and haproxy differently, you could do it.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">A simpler approach would be to build overlays between the sites. It completely depends on your environment/requirements.<o:p></o:p></span></p>
