python - Flower-Celery异步任务监视工具-在Flask/Docker Web API上

Question

无法运行Flower来监视在我的docker部署的flask应用程序上运行的celery异步任务。我已经尝试了所有方法，但是有关在docker部署环境中运行花的文档非常稀少，但我仍然相对较新。

我的docker-compose.yml文件的Web， celery 和花朵部分

version: "3.6"

services:
  web:
    image: <image here>
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
      placement:
        constraints: [node.role == manager] # this parameter should be worker when in the cloud with managers and workers
    command: ./docker_setup.sh postgres postgres_test
    depends_on:
      - celery
    environment:
      - PYTHONUNBUFFERED=1
    secrets:
      - <secret shtuff>
    networks:
      - webnet
    labels:
      - <local deployment label>

  celery:
    image: <image here>
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
      placement:
        constraints: [node.role == manager] # this parameter should be worker when in the cloud with managers and workers
    command: celery worker -A celery_worker.celery --loglevel=info
    depends_on:
      - postgres
      - redis
    environment:
      - PYTHONUNBUFFERED=1
    secrets:
      - <secret shtuff>
    networks:
      - webnet
    labels:
      - <local deployment label>

  flower:
    image: <image here>
    environment:
      - PYTHONUNBUFFERED=1
    working_dir: /code
    command: celery flower -A celery_worker.celery --port=5555
    depends_on:
      - postgres
      - redis
      - celery
    ports:
      - "5555:5555"
    links:
      - db
      - redis
    networks:
      - webnet

当我通过docker本地部署(以便可以通过 localhost访问Web API)时，它运行良好，并且可以通过celery日志查看该应用程序正在运行并顺利处理异步请求。但是，当我尝试通过执行 $ flower并转到 http://localhost:5555来访问花监控应用程序时，花应用程序会加载，但未显示任何线程或工作程序。任何建议或帮助将不胜感激!

哇。愚蠢的疏忽并忘记了在我的应用程序的我的requirements.txt文件中包括flower==0.9.2。完成该操作后，在进行本地部署后，flower在localhost:5555上公开。奇迹般有效!
