Flower is a web-based tool for monitoring and administrating Celery clusters. By connecting to the node that contains Celery, you can see the behaviour of all the workers and their tasks in real-time.
To bring up the frontend, run this command `$ kubectl create -f examples/celery-rabbitmq/flower-controller.yaml`. This controller is defined as so:
First, start the flower service with `$ kubectl create -f examples/celery-rabbitmq/flower-service.yaml`. The service is defined as below:
```yaml
apiVersion:v1
kind:Service
metadata:
labels:
name:flower
name:flower-service
spec:
ports:
-port:5555
selector:
app:taskQueue
component:flower
type:LoadBalancer
```
It is marked as external (LoadBalanced). However on many platforms you will have to add an explicit firewall rule to open port 5555.
Now you know on which host Flower is running (in this case, 10.245.1.4), you can open your browser and enter the address (e.g. `http://10.245.1.4:5555`. If you click on the tab called "Tasks", you should see an ever-growing list of tasks called "celery_conf.add" which the run\_tasks.py script is dispatching.
Point your internet browser to the appropriate flower-service address, port 5555 (in our case http://162.222.181.180:5555).
If you click on the tab called "Tasks", you should see an ever-growing list of tasks called "celery_conf.add" which the run\_tasks.py script is dispatching.
