User folder setup

[noootch]

Hello all,

in #141 I suggest a change from config.py to a json config.

In the PR I have two possible solutions to define a user directory:

1. via command line
2. via env var

The problem I see in this is that if someone uses both variants, sooner or later there might be an issue, when changing the directory in one of these methods.

I would like to reduce the options to either CLI args or ENVVAR.

What are your opinions on this?

Make CLI overwrite ENVVAR.

I'm Not Sure If this ist helpfull. The Server should Run in a docker env, so starting the py Code directly will be for devs only

good point. Then I guess envar(s) would be enough. Especially when run in a container. CLI is some effort for a clean implementation.

I suggest using https://pypi.org/project/python-decouple/ it's perfect for several settings. env vars but also config files like .env or similar.

it gives the flexibility that you usually need.
