How to setup a WLAN Interface passthrough into a Docker container?

I have the need to passthrough a WLAN Interface into a Docker container. My goal is to setup the container so, that it uses the WLAN Interface to create a AP and Captive Portal. I created a base image with the tools I need and copied some configs into it: FROM ubuntu:22.04 ENV DEBIAN_FRONTEND=noninteractive RUN apt-get update \ apt-get install -y --no-install-recommends \ hostapd \ dnsmasq \ iproute2 \ iputils-ping \ net-tools \ vim \ sudo \ systemctl \ apt-get clean rm -rf /var/lib/apt/lists/* COPY config/hostapd.conf /etc/hostapd/hostapd.conf COPY config/dnsmasq.conf /etc/dnsmasq.conf WORKDI
