Hi I am Harish Kumar, Master Student at BTH, Karlskrona, Sweden. I am working on my Master thesis at BTH and my thesis topic is Performance evaluation of OpenStack with HTTP/3. Welcome Harish! That should be interesting to see the results of your evaluation. I hope you will share that with the community once you complete your research.

I have successfully built curl and nginx with HTTP/3 support and I am performing some commands using curl for generating tokens so i could access the services of OpenStack. OpenStack relies with the Apache web server and I could not get any results using Nginx HTTP/3 . I would like to ask if there is any official documentation on OpenStack relying with Nginx?, I have searched in the internet reg. this info but could not get any, I would like to use nginx instead of apache web server , so I could get some results by performing curl and commands and nginx web server (with http/3 support). Please let me know and if there is any content please share with me. I hope you have understood this. It would be helpful for my Master Thesis.

I haven't really done anything with HTTP/3, but from what I understand, it just changes the transport to use QUIC. So that should be pretty transparent as far as the OpenStack services are concerned. We don't have any documentation that I know of. Unless someone has done some of their own testing and has some notes they can share. I think the main thing here would be just setting up nginx to use the uWSGI apps rather than Apache. This seems like a promising article that walks through configuring nginx: https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applicat... That specifically references flask, so just keep in mind that most OpenStack services do not use that part of the tutorial. Cinder has some old notes from when we were first looking at running behind Apache. Those can be found here: https://docs.openstack.org/cinder/latest/contributor/api.apache.html But you may just need to look at the existing Apache configuration and figure out what to change to do the equivalent under nginx. Good luck! Sean
