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

You need to be able to run a Java 6 Swing GUI in a container. To get the GUI environment working might be tricky e.g. on MacOS see https://stackoverflow.com/questions/37826094/xt-error-cant-open-display-if-using-default-display
