This fork resolves the issues mentioned here.
As a bonus, it's a multiarch build. You can use it with arm and x86.
The built image can be found here: https://hub.docker.com/repository/docker/timsch12345/erpnext-customized

If you just want to use the built image:

1. Copy the compose.yml file and the example.env file.
2. update the example.env as needed - especially the passwords and the traefik domain
3. up the containers. I expect you to have a ready Traefik build. If not, please see somewhere else how to do that or use ports instead of expose.

The built image has the addional apps

• erpnext_germany
• hrms
• payments

If you need more, you'll have to build it yourself. To easily build, you can use the docker-build.sh file. You may have to edit it slightly.
