Hi, you might want to check this ERPNext Docker Debian.

I believe it's more stable and dockerfile and readme file is better written.

Dockerfile for building Self-contained ERPNext Image on CentOs

This repository contain Dockerfile use to build Docker Images in Docker Hub pipech/erpnext

You might or might not be able to run docker images using this repository because it's heavily base on other repository like frappe/bench, frappe/frappe and frappe/erpnext

So I think it's best to run using image from Docker Hub pipech/erpnext there I already clone, install those repository into Docker Images

What Dockerfile does

Please see it for yourself here, it's self explanatory.
