Flower in docker-compose

[yccheok]

Instead of

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

in docker-compose.yml

It gave me error

C:\flask-celery-docker-scale-master>docker-compose up monitor

Instead, I need to change it to

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