Add user and group Linux Alpine Dockerfile

RUN apk add --no-cache sudo


# creates a pcluser with no password
# then set password to 1234
# this is necessary since adduser from Alpine Linux
# will prompt a password without the --disabled-password flag

Docker Display GUI with X server

Displaying a GUI based application in Docker is typically a moment of stackoverflow search, for the sake of time, and for the reckless lazy ones, the easiest solution is to give xhost permission and then remove the permission.

A possible error when displaying things inside a docker container will go along the lines of:

ERROR: In /build/vtk6-VHOYAG/vtk6-6.3.0+dfsg1/Rendering/OpenGL/vtkXOpenGLRenderWindow.cxx, line 1475
vtkXOpenGLRenderWindow (0x563fbe453620): bad X server connection. DISPLAY=:1. Aborting.

• Running container must have installed gdb
• Install Remote-containers extensions in your local vscode application
