File Editor - Docker there are container that could help?

Hi @Luca_Garofalo , I found your solution when i was starten to install HA Docker and would like to add the File Editor container. I installed it as a docker container, but when i start the file editor it ends-up at a totally weird location in the file system; Obvious, i did something wrong, hopefully you can help me.
Mij docker-composer looks like this:

## File Editor (Configurator)
  file_editor:
    container_name: configurator
    image: causticlab/hass-configurator-docker:arm
    restart: unless-stopped
    volumes:
      - /home/iotstack/docker/configurator:/config
      - /home/iotstack/docker/homeassistant/.homeassistant:/home/docker/homeassistant/.homeassistant
    ports:
      - "3218:3218"

And my iframe cfg in configuration.yaml is this:

panel_iframe:
  file_editor:
    title: 'File Editor'
    url: http://192.168.178.240:3218
    icon: mdi:wrench-outline

With this configuration i end op here in the file system:

Can you tell me what i am doing wrong here?
