<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">There are three ingress controllers. One for kube-system services, one for openstack services, one for mariadb dedicatedly. With current simplex deployment, by default, there are no ingress created in kube-system
namespace (I didn’t see it in my deployment). In openstack namespace, I can see many ingresses created, like aodh, barbican, ceilometer, cinder, glace, horizon, nova, keystone, neuron, etc.

<p class="MsoNormal">Hi Brent,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am working on the bug <a href="https://bugs.launchpad.net/starlingx/+bug/1823803">
https://bugs.launchpad.net/starlingx/+bug/1823803</a> which is about large nginx worker process number. With current starlingx code, there are three nginx ingress controllers, one for kube-system namespace ingress, one for openstack namespace ingress, and the
last one for mariadb. Each controller creates as many worker processes as the number of cores.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have initialized three patches to fix this issue. I have no idea about how much the workload of the three ingress controllers will be, so I temporally set the number of worker processes as 1. Do your experts have any suggestions on this
setting? Thanks. <o:p></o:p></p>
