Feedback on how to run a Desktop Gambas Application into a Docker container

[Linus <olivier.cruilles@xxxxxxxx>]

Hello all,

Like previously the feedback about how to run a Gambas Web Application into a Docker container,
today is the turn of how to run a Gambas Desktop Application.

The main differences are:
- the command line executed into the Docker Container for a Gambas Desktop Application
is the *.gambas executable itself rather than the Web Server process in the case of a Gambas Web Application.
- The options used in the command line to start the Docker Container

You will find here a little video showing how to start a Gambas Desktop Application into a Docker Container + the Gambas demo Project + the Docker project to build the Docker Image of the Gambas Desktop Application 

Docker_Gambas_Desktop_Application <https://drive.google.com/drive/folders/1D6Q8bsilYRq4RKcybVl6pEyUOTD-dOt0?usp=sharing>


Here is an example of the Docker command line to start a Graphic Application 

xhost +local:docker ; \
docker run -it --name calculateurdegrade \
--privileged \
--net=host \
--env="NVIDIA_DRIVER_CAPABILITIES=all" \
--env="DISPLAY=$DISPLAY" \
--env="QT_X11_NO_MITSHM=1" \
--volume="/tmp/.X11-unix:/tmp/.X11" \
calculateurdegrade:202508
 

The only bad point on this kind of solution to embedded a Gambas Desktop Application, is the size of the Docker Image produced (in this example 746MB)
but the size does not affect at all the time to start the application, that’s the magie of Docker...

In the end the Docker Image can run the Application on any Linux distribution because all the necessary for the Graphic Application is inside the Docker Container.


I hope this project will interest/help someone
