Provide simple docker image for API devs

[metas-ts]

Type of issue

Feature request

Current behavior

• Currently when developing against metasfresh-webui-api,
  one needs to install npm and node locally, in order to run the frontend.

Expected behavior

I would like to kave a simple docker image which i can fire up locally or on a nearby machine.
I would like to pass the URL of the API as environment varibles.
The way i'd start up that container mignt look like this:

docker run -d -e API_URL=<url-of-my-dev-workstation>-p3000:3000
--name tobis-dev-webui-frontend metasfresh-webui-dev

The benefit would be that i can simply start the frontend either on my workstation or maybe on a dedicated linux box somewhere in the office. At any rate, as a java developer, i would not have to install npm and node.js on my local machine.

We provide config for frontend with config.js file located in root, next to index.html. Unfortunately frontend JavaScript cannot read OS environment variables, so you will need some sh script to launch it while building Docker image that will generate config.js file for you from env vars.

I.e. config_from_env.sh:

#!/bin/bash
echo "const config =  {"
echo "    API_URL: '$API_URL/rest/api',"
echo "    WS_URL:  '$API_URL/stomp'"
echo "}"

Then:

RUN config_from_env.sh > config.js

@metas-ts pls check gh1013-webui branch for Docker-enabled version. I made it unified to work with localhost and Docker – both.
