feat: docker container

[domcyrus]

Add a Dockerfile and job to build it during package workflow.

#69

[domcyrus]

@GyulyVGC this works on my feroda 41 using following steps:

docker build -t sniffnet .

docker run -it \
  --net=host \
  -v $XDG_RUNTIME_DIR/$WAYLAND_DISPLAY:/tmp/$WAYLAND_DISPLAY \
  -e WAYLAND_DISPLAY=$WAYLAND_DISPLAY \
  -e XDG_RUNTIME_DIR=/tmp \
  -e RUST_BACKTRACE=full \
  -e ICED_BACKEND=tiny-skia \
  --cap-add=NET_ADMIN \
  --cap-add=NET_RAW \
  sniffnet

I created a draft because I think it would be good to test some things a bit more e.g. on different linux versions maybe and with and without gpu. And certainly add some documentation because this approach is not OS agnostic for example if you would like to use the container on windows or mac it might be a bit more challenging as you would need to have wayland running on mac. Please let me know how you want to deal with this.

Thank you very much 🔥

I think before testing it'd be nice to make this as platform agnostic as possible, as it's one of the main purposes is the container.

[domcyrus]

@GyulyVGC regarding platform agnostic. AFAICT docker images ARE platform dependent and can't be made platform agnostic. That said I've altered the github workflow docker job to build various different images for each platform.

          platforms: linux/amd64,linux/arm64,linux/386,linux/arm/v7

I've also tested using docker buildx locally like this:

 docker buildx build --platform linux/arm64 -t domcyrus/sniffnet:arm64 --load .

It took a bit of time to compile it ;) but it looks alright to me.

Let me know what you think about this approach.

[GyulyVGC]

Thank you very much again.

I'm pretty busy these days, will check and test as soon as I get some time.
