Faced the same issue with RabbitMQ. Here is how I have it works:
```yaml
rabbitmq:
image: rabbitmq:3-management
flower:
image: mher/flower
ports:
- 5555:5555
command:
- "celery"
- "--broker=amqp://guest@rabbitmq:5672//"
- "flower"
- "--broker_api=http://guest:guest@rabbitmq:15672/api//"
depends_on:
- rabbitmq
```
Brokers & other tabs will show up.
