KEDA Prometheus Scaler

Overview​

Kubernetes Event-Driven Autoscaling (KEDA) can scale workloads based on events from various sources, called "Scalers". It has a Prometheus Scaler, that can query metrics from Oodle.

This guide shows you Oodle-specific configurations for KEDA's Prometheus Scaler.

Prerequisites​

To connect KEDA to Oodle via Oodle's Prometheus API, you will need the following:

  • OODLE_INSTANCE: Your Oodle instance ID
  • OODLE_API_KEY: Your Oodle API key for authentication

Configuring KEDA to Query Oodle​

Set serverAddress and customHeaders for each prometheus trigger of the ScaledObject:

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata: ...
spec:
  ...
  triggers:
  - type: prometheus
    metadata:
      serverAddress: https://<OODLE_INSTANCE>.api.oodle.ai
      customHeaders: "X-API-KEY=<OODLE_API_KEY>,OODLE-INSTANCE=<OODLE_INSTANCE>"
      query: |
        sum(
          rate(
            http_requests_total{
              namespace="default"
            }[2m]
          )
        ) / sum(
          http_server_count{
            namespace="default"
          }
        )
      threshold: "10"
      activationThreshold: "1"
