Can't reach server running inside Docker container

[ggalmazor]

Hi! I'm wrapping my sphinx dev environment inside a Docker container to make it portable and easier to use for other users and I'm interested on adding sphinx-autobuild into it.

Up to now, I was able to run a python -m http.server inside the container and access it from my host machine, no problem.

I've made some tries with sphinx-autobuild and the building part works great but I can't access the web server, even though I've EXPOSEd the port I'm using in my Dockerfile and I'm binding a host port to it, as with the http.server module.

It seems that the server the sphinx-autobuild module is starting isn't getting my hosts requests.

Any idea on how to run it on debug mode, or have some logs to look further into this issue?

I ran into this same issue - the trick for me was to change the host from 127.0.0.1 to 0.0.0.0. Here is my CMD in my Dockerfile (I am running on port 8181):

CMD ["sphinx-autobuild", "--host", "0.0.0.0", "--port", "8181", "docs/source", "docs/build"]

Thanks, @iicky!

Honestly, I had solved the issue somehow. I'll review what I did and leave feedback here :)
(might as well be just what you've commented)

@ggalmazor Awesome, keep me posted - definitely excited about having this tool!

Yup, it was --host 0.0.0.0 what I did.

I also had to add --poll because automatic change detection doesn't work well on Windows, but it didn't affect our Linux and macOS users.

I guess we can close the issue now :)
