You can customize the network password and other configurations on files at confs/hostapd_confs/. You can also add your own hostapd configuration files here.
Management using plain docker
Add --rm for volatile containers.
Create and run a container with default (Open) configuration (stop with Ctrl+C)

Create and run a container with WEP configuration (stop with Ctrl+C)
docker run --name autowlan_wep --cap-add=NET_ADMIN --network=host -v $(pwd)/confs/hostapd_confs/wep.conf:/etc/hostapd/hostapd.conf autowlan
Create and run a container with WPA2 configuration (stop with Ctrl+C)
docker run --name autowlan_wpa2 --cap-add=NET_ADMIN --network=host -v $(pwd)/confs/hostapd_confs/wpa2.conf:/etc/hostapd/hostapd.conf autowlan
Stop a running container
docker stop autowlan_{open|wep|wpa2}
Management using docker-compose
Create and run container (stop with Ctrl+C)
docker-compose -f <fichero_yml> up
Create and run container in the background
docker-compose -f <fichero_yml> up -d
