Help trying to make a Dockerfile

[maxlein]

As it not that easy to get all the dependencies in and get this to work, I thought of adapting the Dockerfile of the original repos author to ROS2 and this version here.

Think there are only some minor things missing but maybe the autor can help here.
For example in the 3D grid example it says Error displaying widget: model not found when trying to view the ros3d.Viewer().

ipywidgets are installed, because calling a slider directly works but not when using jupyros.

Running the below Dockerfile leads to a running jupyterlab with ros2 support.

Dockerfile:
