For those who are looking for the solution too:
Crutial part is to enable x11:
RUN apt-get update
RUN apt-get install -y x11-apps
Container will be run with some thing as following (ubuntu):
docker run -it -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix osbot
Are there any templates available somewhere? If there are none, what would be suggestions... like: windows or linux based? Any good Idea what else could be included other than the client ( I know depends on the application, but maybe there is something standard that could be included I did not think of... like standalone sql container.... etc). I am just starting and I was wondering if it is possible to find anything regarding the topic.
