[Starlingx-discuss] About Nginx worker process number

[Xie, Cindy]

Yi,
What service request will Nginx accept and process, and on what kind of frequency? Just need to evaluate how it is being used and the required responsiveness.

Thx. - cindy

Hi all,

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

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.
