Hello,
<div><br>
</div>
<div>Currently only one region is supported in devstack-gate, there are lots of projects providing multi-region involved features, for example, heat multi-region, tacker multi-vim, shadow multi-cloud, tricircle networking across multi-region, kingbird resource
sync and so on.</div>
<div><br>
</div>
<div>Thanks to the patch "Introduce roles into the feature matrix", it's possible to assign the sub-node in devstack-gate with a new role "subnode_multi_region", so that all services will start and share same keystone in the primary node, this is the typical
devstack multi-region mode. One environment variable MULTI_REGION is introduced to enable the sub-node running as the second region(currently the first step is to setup two-node two-region environment).</div>
<div><br>
</div>
<div>One patch was prepared to enhance devstack-gate: <a href="https://review.openstack.org/#/c/412777/" target="_blank">https://review.openstack.org/#/c/412777/</a></div>
<div>And Tricircle will begin to try the multi-region gate/check job: <a href="https://review.openstack.org/#/c/414909/" target="_blank">https://review.openstack.org/#/c/414909/</a></div>
<div>The devstack plugin of Tricircle is also enhanced to support multi-region job: <a href="https://review.openstack.org/#/c/414860/" target="_blank">https://review.openstack.org/#/c/414860/</a></div>
<div><br>
</div>
<div>How do you think about this idea? It's basic requirement to have multi-region gate/check job for Tricricle, hope this could be on board before Ocata release. once Tricircle can be tested through such a multi-region job, other projects can also benefit
from the same infrastructure.</div>
