cannot create directory ‘public/js’: Permission denied - Rootless docker

Hey Nick, first of all, thank you so much for this amazing repo, man, it is helping me a lot.

I just want to check with you if it is possible to run this repo in an env where docker is installed as rootless.

When I run docker compose up in my nixos, with "root-full" docker, everything works fine, but doesn`t work if I run in a rootless docker.

Will share here some outputs.

I ask for your help, please.

Thanks in advance.

Start by inspecting docker-compose.yml and Dockerfile, then reproduce the reported rootless command docker compose run web mkdir public/js. Done means the web service can create public/js under rootless Docker without the reported permission error, while the existing service setup continues to work.
