Using the Docker image for Kali on a Raspberry Pi, no networking

Hi all,

while deploying the Docker Kali image (kalilinux/kali-rolling:armhf) on a Raspberry Pi 4 I'm not able to use apt to install the necessary Kali packages and tools.
When I start the docker container with --net=bridge I can see an IP address being active while running "hostname -i" but "apt update" remains on 0%.
I can ping the container's IP from the Pi and I see iptables rules in place and ip_forward active, yet no network for the container.

What am I missing?

Cheers,

BC
