Notice:

• This scaler will never scale to 0 and even when user defines multiple scaler types (eg. Kafka + cpu/memory, or Prometheus + cpu/memory), the deployment will never scale to 0.
• This scaler only applies to ScaledObject, not to Scaling Jobs.

Trigger Specification

This specification describes the memory trigger that scales based on memory metrics.

triggers:
- type: memory
  metadata:
    # Required
    type: Utilization/ AverageValue
    value: "60"

Parameter list:

• type - Type of metric to use. Options are Utilization, or AverageValue.
• value - Value to trigger scaling actions for:
  • When using Utilization, the target value is the average of the resource metric across all relevant pods, represented as a percentage of the requested value of the resource for the pods.
  • When using AverageValue, the target value is the target value of the average of the metric across all relevant pods (quantity).

Example

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata:
  name: memory-scaledobject
  namespace: default
spec:
  scaleTargetRef:
    name: my-deployment
  triggers:
  - type: memory
    metadata:
      type: Utilization
      value: "50"
