Description
Motivation¶
Apache in prefork mode uses a lot of resources to provide mediocre performance.
Acceptance criteria¶
- AC1: It is known if Nginx rate limiting features work for our use cases
- AC2: Nginx has been deployed successfully on OSD
Suggestions¶
- Make sure there is an easy way to switch back to Apache in case something goes wrong
- See #129490 for results from O3
- Adapt O3 nginx config for HTTP + HTTPS (O3 only requires HTTP)
- Add changes to salt-states-openqa including monitoring: we have multiple panels regarding apache that need to be adapted for nginx as applicable
- Ensure that we have no alerts regarding "oh no, apache is down" ;)
