[scipioni]

in docker-compose.yml

Same problem. No changes in queue or flower container.

@scipioni suggested change "fixes" the issue. It would be nice to know why it is an issue to begin with, though.

Since the way celery is written has changed, the easiest way to solve this problem is to pass the value as an environment variable. The easiest way to solve this problem is to add CELERY_BROKER_URL as an environment variable to flower in docker-compose.yml. Please remove the existing command.

flower:
...
    environment:
        - CELERY_BROKER_URL=amqp://guest@queue:5672//
...

Ok I’ll try that. Thanks.

To add onto okamop's answer;
According to Flower's Docker page

Important Please note that from version 1.0.1 Flower uses Celery 5 and has to be invoked in the same style as celery commands do.

The key takeaway here is that the Celery app's arguments have to be specified after the celery command and Flower's arguments have to be specified after the flower sub-command.

This is the template to follow::

celery [celery args] flower [flower args]

With the fix in this commit

- ENTRYPOINT ["flower"]
+ CMD ["celery flower"] 

Which means we also need to delete the command: block for Flower to start correctly.

I ran into a Flower 0.9.7 issue that is resolved in their latest container image and couldn't continue using version 0.9.7.

  flower:
    image: mher/flower
    networks:
      - ${TRAEFIK_PUBLIC_NETWORK?Variable not set}
      - default
    env_file:
      - .env
    environment:

    deploy:
      labels:

I don't know about the "Broker tab" comment and dropped it.

I googled for hours but unfortunately I couldn't find a solution until I found yours. Thank you.
