Expected behaviour

Seems like this theme uses absolute_url, which will yield urls like 0.0.0.0:PORT when you use it with docker. I've noticed that your other theme "so-simple" works well with docker as it uses relative_url. I was wondering if there's a reason for that. I'd be happy to update it all and send you a PR, but wanted to check with you first if there's a reason. Should all work the same after the update.

Are you correctly assigning JEKYLL_ENV=production at build? Jekyll defaults development, which overrides url with localhost... or in your case 0.0.0.0:PORT.

Give production a try first. absolute_url could likely be changed to relative_url, but I think your issue is the environment flag. You might want to search through the closed issues as I know I've seen others who had the same problem and solved it without messing with the theme.

Here's how to solve it. Closing as this is a duplicate.

Thanks @mmistakes. I'd already tried that, but it doesn't quite solve the problem. When you set the build for production, you're basically saying "use the url as it is in my _config.xml". In the example you gave me, the author changes the url to be what they want locally. However, deploying this to production would mean changing that again, which is prone to errors.

Ideally, if you use a relative path instead, the url stops getting on the way.

This is where multiple config files can come into place. You can daisy chain them in your build command.

Specify config files instead of using _config.yml automatically. Settings in later files override settings in earlier files.

ref: https://jekyllrb.com/docs/configuration/

# _config.yml
# contains all your normal configs

# _config.dev.yml (or whatever you want to name it)
# add any variables you want to override for development purposes

url: http://localhost:4000

Then your Jekyll build command would change to jekyll serve --config _config.yml,_config.dev.yml

Right on! Doing that solved it.

Still think it would be easier to just use relative urls to avoid the "hackery" around how you start Jekyll, but this completely solved it.

Thank you for the responsiveness!
