Why Kivy does not work on docker

note.md

install python with KivyMD

===== using python alpine base image

1. cd /home
2. mkdir workspace
3. apk add --no-cache jpeg-dev zlib-dev
4. apk add --no-cache --virtual .build-deps build-base linux-headers && pip install pillow
5. apk add mesa-dev
6. pip install kivymd

===== use conda base image

1. cd /home
2. mkdir workspace && cd workspace
3. conda create --name kivyenv -y
4. conda activate kivyenv
5. conda install kivy -c conda-forge -y
6. python -m pip install kivymd
7. apt-get update
8. apt-get install libmtdev-dev libgl1-mesa-glx -y

cannot be done because there is no reliable way to porting display from docker to host Every time calling App will return Cannot connect to server X and abruptly exit
