Trigger scaling of multiple Deployment with the same Kafka metrics

[alessio1983lx]

Hi, here is my scaled object:

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata:
  name: kafka-scaledobject
spec:
  scaleTargetRef:
    name: nginx-deployment 
  pollingInterval: 5
  cooldownPeriod: 10
  minReplicaCount: 0
  maxReplicaCount: 1
  advanced:
    restoreToOriginalReplicaCount: true
  triggers:
  - type: kafka
    metadata:
      bootstrapServers: kafka-kafka-bootstrap.default.svc.cluster.local:9092
      consumerGroup: cli-group
      topic: topic1
      scaleToZeroOnInvalidOffset: "true"
      offsetResetPolicy: earliest
      lagThreshold: "1"

It scales the nginx-deployment deployment to replica 1 when there is a message on the kafka topic, it scale to zero when it is consumed by a consumer in the consumer group kafka-cli

If i want to trigger the scaler to more than one Deployment with that metric, should i just create other scaled objects with different name, target deployment and same trigger? Or is there another best practice?

Thanks for the replies

Bye!

Yes, you should just create other scaled objects with different name, with other scaleTargetRef and you can use the same trigger
