How to use flower to monitor more than 1 worker

Question

Currently, I create a Celery worker + Flower monitoring solution based on

https://github.com/itsrifat/flask-celery-docker-scale

Celery worker and Flower monitoring both run in a same directory flask-celery

The reason is that, so that Flower has access to Celery worker code module, and the following command with -A flag would work

entrypoint: flower
command: -A tasks --port=5555 --broker=redis://redis:6379/0

This is what their docker-compose.yml looks like

worker:
  build:
    context: ./flask-celery
    dockerfile: Dockerfile
  depends_on:
    - redis
monitor:
  build:
    context: ./flask-celery
    dockerfile: Dockerfile
  ports:
    - "5555:5555"
  entrypoint: flower
  command:  -A tasks --port=5555 --broker=redis://redis:6379/0
  depends_on:
    - redis

Now, I would like to create another new worker task2.py code, which will sit inside new directory called flask-celery2.

So, how should I modify the Dockerfile and docker-compose.yml so that flower will be capable of monitoring both tasks and tasks2?

Answer 1

yes, you have to get this new worker running in a separate container(best practice) and configure in the dockerfile, then flower can automatically monitor this task as long as it is being pushed into the same message broker.

You have to use below steps. You have to to your project folder.

pip install flower
flower -A proj --port=5555

Then you can see in and check in your celery task in browser like http://yourIP:5555
