[Docker] is installing bluez on the host a requirement?

[beloso]

I had Bluez installed on my host.
And I have room-assistant running via docker.
Everything worked.

I thought I could uninstall Bluez from the host.
Room-assistant started failing.

Is Bluez a requirement for the docker host?

Here is the compose part:

  roomassistant:
    image: mkerix/room-assistant
    container_name: roomassistant
    restart: always
    depends_on:
      - homeassistant
    cap_add:
      - NET_ADMIN
    network_mode: host
    volumes:
      - $DOCKERDIR/roomassistant/config:/room-assistant/config
      - /var/run/dbus:/var/run/dbus
    labels:
      ## Watchtower
      - "com.centurylinklabs.watchtower.enable=true"

Your need some sort of bluetooth protocol stack like bluez on your host machine, so that room-assistant can talk to the device.
So unless you install another one, you can't remove it.

Thanks for clearing it up. I have no issues with having bluez installed on the host.
I just didn't understand that need.
