    container_name: ha-auto-guest-login
    environment:

      - URL=http://homeassistant.local
      - DASH=lovelace-guest
      - USER=username
      - PASS=password

  -e URL=http://homeassistant.local \
  -e DASH=lovelace-guest \
  -e USER=username \

Parameters

Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Parameter	Function
-p 80	WebUI
-e CLIENTID=http://homeassistant.local/	Usually matches URL. See Getting ClientId for instructions on finding it
-e URL=http://homeassistant.local	URL of Home Assistant instance
-e DASH=lovelace-guest	Home Assistant Dashboard to automatically be directed to. In this example setup: http://homeassistant.local/guest-dashboard
-e USER=username	Home Assistant user that is automatically logged into
-e PASS=password	Password of Home Assistant user above
