add Containerfile

[Ptosiek]

Hey,
It's a tentative try to start using containers for development and avoid having specific MacOS/Windows behavior.
Note that it's using python bookworm image, we can change to bullseye if needed. (Also tried with a pure debian image but the handling of python deps comes with some headaches, it's just easier that way)

I don't have a Mac handy to test so this is probably not working 'as is'.
Found this gist:

(If you don't use Windows either, I wouldn't bother much making this work for it)

I'm using podman but docker should work too:

1. Build with

podman build . -t pizero_bikecomputer

2. Run with

podman run -v .:/opt -v /tmp/.X11-unix:/tmp/.X11-unix -e "DISPLAY=:0" pizero_bikecomputer

Hi @Ptosiek ,
thank you for your PR.
I haven't been able to get it up and running on both docker and podman on macOS yet, but it's a good opportunity so I'll keep trying until I do.
