Transparent mode failure: FileNotFoundError(2, 'No such file or directory')

Steps to reproduce the problem:

1. start ap and redirect tcp 80/443 stream to 8080
2. pull and start mitmproxy for raspberrypi model 3

docker run -it --rm -p 8080:8080 mitmproxy/mitmproxy:4.0.3-ARMv7 mitmdump -m transparent -p 8080 -v 

and it shows:

...
clientconnect
Transparent mode failure: FileNotFoundError(2, 'No such file or directory')
ProtocolException("Transparent mode failure: FileNotFoundError(2, 'No such file or directory')",)
clientdisconnect
...

I think --network host may actually work. 😃

The error persists when I use a local Docker container though, so it is nothing k8s specific. I will continue searching, thanks for the hint @mhils ! If I find the solution I will document it here for others to find if this is ok. At least someone seems to have managed to get it working (though on an old k8s and docker version): https://github.com/danisla/kubernetes-tproxy
