This is actually beautiful. Would be great to see this in the main as well.

This fix don't work anymore and has multiple conflicts.
Is there another solution to map the local UID and GID?

What about this? https://docs.docker.com/engine/security/userns-remap/

I tried to remap the user but it doesn't seem to work either:

{
  "userns-remap": "myuser"
}

I like the solution of laravel/sail. They are able to map the local UID/GID automatically - and to override is also possible of course.

They have a startup/entrypoint script which makes a usermod's the applications user ID (in craft cms case this would be nginx).

Unfortunately I wasn't able to recreate something like that on my system (probably it has to do with the docker context I didn't get).

But I was able to create a custom image with hardcoded values:

FROM craftcms/nginx:8.2-dev

USER root

RUN set -ex \
    && apk upgrade --no-cache \
    && apk add --no-cache \
        shadow

RUN usermod -u 1000 www-data && groupmod -g 1000 www-data

RUN chown www-data /run/nginx.pid
RUN chown www-data /run/supervisord.pid
RUN chown -R www-data:www-data /var/lib/nginx/

USER www-data

My knowledge about docker is limited, so I'm not sure what would be the best solution to adjust the current implementation - and how to exactly build the craftcms/docker project itself on my system locally.

Nevermind, I've created a fork from laravel/sail and adjusted it so it works with craft perfectly.
