When using Windows Subsystem for Linux Version 2 on Windows there may be permissions error because of using the same volum on the host and in the container.
If files are owned by the host-user WordPress can't install/update/delete plugins/themes/media, when owned by the apache user (33) inside the container, the host-user can't edit the files.

I want to be able to edit theme and plugin files on my local host (IDE) and also allow WordPress to write files.
Until now I used a hacky bash-script to always overwrite the file permissions via chown and a sticky group bit, which didn't really work well.

Since this image (especially the docker-compose.development.yml) is only for local development permission escalation / security is not such a big risk. Therefore it would be easier to run the container and apache as the same user / group id as the local user.

/etc/passwd and /etc/group may need to be mounted as well (read only) to sync the user ids, depending on the host distro and the user/group id used (maybe user 1000:1000 already exists in the container?). If you encounter some file permissions about temporary files, this may be the reason.
