Is this a new feature request?

• I have searched the existing issues

Wanted change

Add ngx_http_v3_module to support http3

Reason for change

HTTP3 adds many performance improvements compared to HTTP2.
SWAG is based on Alpine 3.21 and NGINX 1.26.2 which both support HTTP3 NGINX module.
The request was declined before based on older versions that didn't support the HTTP3 module, now it should be possible:

There’s an upstream PR to build nginx with the http3 module https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/76753. But it would be built with openssl which means no 0-rtt.

Thanks, I'll try and find time to take a look at this, might take a little while because we'll have to do some thorough testing first.

Hi @thespad, have you made any progress on this front?
I'm available to test a build if you need a guinea-pig :)

I'm currently targeting the Alpine 3.22 release in ~April to implement this in a way that doesn't risk impacting any other images, as it really needs doing on our nginx base, which a lot of things rely on.

A new base version means nothing is using it yet, so it's safe to experiment with. I can get the nginx base updated and a PR build pushed for swag so people can test it and we can shake out any issues.
