On your docker host:
modprobe mac80211_hwsim
If you're running docker-ce on macOS or Windows, the fake docker host doesn't have kernel support for wifi, rather run your docker host in a VM. If you do want to make your docker-ce work with a custom kernel, check this article.
Pull it from docker hub.
docker pull singelet/shinai-fi:latest
or build the container yourself
docker build -t shinai-fi .
docker run -it --privileged --network host singelet/shinai-fi:latest
Try some wifi hacking, e.g.:
airmon-ng start wlan0
airodump-ng wlan0
You can also set up a mana rogue AP and see a client connect.
