mysqld.address never applied

I am trying to use the exporter in docker with mysqld on the host machine.
Both inside docker ("localhost) does work.

Exporter does not seem to take the host setting, no matter what I try. It seems the host is hardcoded to localhost in the latest version.

You can clearly see in the log it is using localhost. Even changing the port does nothing.

compose:

  mysqld-exporter:
    image: prom/mysqld-exporter:latest
    container_name: monitoring_mysqld_exporter
    environment:
      - MYSQLD_EXPORTER_PASSWORD=xx
    volumes:
      - /var/docker_images/mysqld_exporter.cnf:/cfg/mysqld_exporter.cnf
    command:
      #- "--config.my-cnf=/cfg/mysqld_exporter.cnf"
      - "--mysqld.username=exporter"
      - "--mysqld.address=xxx:3306"
      - "--no-collect.slave_status"
    restart: unless-stopped
    ports:
      - 9104:9104
    expose:
      - 9104
    networks:
      - traefik
    labels:
      - "traefik.enable=false"
