Hi all,

Any recommends on the setting for the number of nginx worker processes of ingress controllers? Thanks.

Subject: [Starlingx-discuss] About Nginx worker process number

Hi Brent,

I am working on the bug https://bugs.launchpad.net/starlingx/+bug/1823803 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.

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.
