How can I scale Celery workers in Kubernetes?

You can scale Celery workers in Kubernetes by adjusting the number of replicas in your deployment configuration.

What configuration changes do I need to make?

You need to modify the spec.replicas field in your deployment YAML file to the desired number of worker instances.

Is there a way to automatically scale based on workload?

Yes, you can use the Horizontal Pod Autoscaler to automatically scale your Celery workers based on CPU or memory usage.

Can you provide an example of the YAML configuration?

Sure! Here's a basic example:

apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
metadata:
  name: celery-hpa
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: celery-worker
  minReplicas: 2
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 50
