I searched the forum but could not find any way to setup docker with just Frappe Installed on it and nothing else.
Actually I want plain vanilla Frappe Framework setup docker where I can install my custom apps.
In the currently available docker with ERPNext preinstalled I am not able to install my custom app on it.
I enter inside the docker container using this command docker exec -it <mycontainer> sh
Now when I try to install custom app using bench install-app <my custom app> , it gives error Unknown database. After this the container seems to crash as Frappe and ERPNext stops working and in borwser we get Interanal Server Error 500
