MagicDraw in Docker

How to run MagicDraw in Docker container

see also https://community.nomagic.com/running-magicdraw-in-a-docker-container-t5895.html

The goal is to get an older MagicDraw 16.9 working in a container. The following approach has been tested on Mac OS 10.13.6 High Sierra and Ubuntu 18.04 LTS Bionic Beaver.

Prerequisites

Please try out the following Dockerfile and Gui.java first using the build and run scripts.

./build
./run

The Java based gui should appear:
