This is, in general, excellent. Thanks. In the PR workflow, I really wanted two rounds of pulls, and two separate logs, because it's actually testing the cache, so I will rework that back in. Great tips about the cache mode=gha. Formatting wise, I will let shellfmt decide, but thanks for all the short-circuiting removals. I will merge this into a feature branch first, I've a big round of merges to do.

Okay.

Question: Have you faced long python compiling time in mitmproxy when creating arm64 image? Because I am! Almost 1100+ seconds.

[rpardini]

Yes! building arm64 under qemu is ridiculously slow. On real arm64 hardware it's ok, of course. I gotta move the mitmproxy build to the base image https://github.com/rpardini/nginx-proxy-connect-stable-alpine/blob/master/Dockerfile where nginx is already built. Then setup CI there to schedule build every night, even if it's super slow qemu on GHA, we'll never get to experience it.

That would allow for fast(er) arm64 builds of this one, since no building would be done at this level.

I think I should separate changes of this branch in multiple PRs
