Another Container with Rpi+Docker+Portainer

Hi, I am using hassio with docker in Rpi3 ubuntu.
Docker has hassio supervisor, dns, and hassio containers.

I wan to use another container for hassio to use another frequency z-wave stick.

command:
docker run --init -d --name=“k-home-assistant” -v /home/pi/khomeassistant:/config --net=host homeassistant/raspberrypi3-homeassistant:stable

I can see “k-home-assistant’ container is created and start running, but the log shows up 'the port is already used:8123”.
After that, added “server_port:12345” in configuration.yaml of /home/pi/khomeassistant/ to use another port

But no work. new container is still trying to use port 8123.

How can I use port 12345 for another hassio container?

Thanks
