Looks like your app is listening on 127.0.0.1. You may need to listen on 0.0.0.0 instead.

I'm getting this error message when I try to build my project. Is there a simple thing I can add to my Dockerfile to make this fix?

i dont know rails but does RUN RAILS_ENV=development make it listen on localhost? It should be running in prod mode ( whatever that means in rails land )

Rumon•3y ago

And what's the error message?

Finn•3y ago

That it's running on localhost I asume

angelo•3y ago

Yep, this is an issue with your code, not Docker

araik49OP•3y ago

I asked the devs of the project, and they suggested that I add RAILS_ENV=development as an environment variable in Railway, but that seems to produce it's own error. https://github.com/octobox/octobox/issues/3145

I'm using this as the start command, RAILS_ENV=production bundle exec puma -C config/puma.rb Looks like it's getting closer... https://web-production-644b.up.railway.app/ I changed the build command to this, bundle exec puma -C config/puma.rb and added the environment variable to RAILS_ENV=development.

Have your tied letting nixpacks do its thing? Ie not setting any start commands. https://nixpacks.com/docs/providers/ruby Might help, I can see some of the words in your command are on that page. Otherwise you can try creating a dockerfile for your project. Altho nixpacks >>>> dockerfile

Ruby | Nixpacks

App source + Nix packages + Docker = Image

Yeah, I removed my custom start commands and it's building now. Last hurdle is to fix the blocked host error message I'm getting without breaking the successful build. https://web-production-644b.up.railway.app/

Looks like you just need to run a dB migration of some kind?
