Подключить prometheus к celery-flower, запущенных в разных docker.compose.yml

Хочу подключит prometheus к celery-flower. Делаю всё по инструкции - https://github.com/mher/flower/blob/master/docs/prometheus-integration.rst

Есть 2 docker-compose.yml.

app/docker-compose.yml

  celery-flower:
    ...
    container_name: celery-flower
    command: celery -A configs flower -l INFO --url_prefix=flower --port=5555 --persisten=True
    ports:
      - "5555:5555"
    networks:
      - default
      - flower

networks:
  default:
  flower:
    external: true

observability/docker-compose.yml

  prometheus:
    ...
    volumes:
      - $PWD/prometheus.yml:/etc/prometheus/prometheus.yml
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'
      - '--web.console.libraries=/etc/prometheus/console_libraries'
      - '--web.console.templates=/etc/prometheus/consoles'
      - '--web.enable-lifecycle'
    expose:
      - 9090
    ports:
       - 9090:9090
    networks:
      - observability
      - flower

networks:
  observability:
  flower:
    external: true

observability/prometheus.yml

scrape_configs:
- job_name: flower
  static_configs:
  - targets:
    - celery-flower:5555

Всё запускается, но такое ощущение, что prometheus не видит celery-flower. Здесь тоже не находит http://localhost:9090/graph

У обоих контейнеров есть сеть flower (смотрел docker inspect)

Причина была в неверной команде запуска celery-flower, а именно --url_prefix=flower

app/docker-compose.yml

  celery-flower:
    restart: always
    image: mher/flower:1.2.0
    container_name: celery-flower
    command: celery flower -l INFO --persisten=True
    volumes:
      - flower_data:/data
    environment:
      - CELERY_BROKER_URL=redis://redis:6379
    ports:
      - 5555:5555
    networks:
      - default
      - flower
