Targets

Configuring a target provide the Autoscaler with a value that it tries to maintain for the configured metric for a revision. See the metrics documentation for more information about configurable metric types.

The target annotation, used to configure per-revision targets, is metric agnostic. This means the target is simply an integer value, which can be applied for any metric type.

Configuring targets

  • Global settings key: container-concurrency-target-default. For more information, see the documentation on metrics.
  • Per-revision annotation key: autoscaling.knative.dev/target
  • Possible values: An integer (metric agnostic).
  • Default: "100" for container-concurrency-target-default. There is no default value set for the target annotation.

Target annotation - Per-revision

  1. apiVersion: serving.knative.dev/v1
  2. kind: Service
  3. metadata:
  4.   name: helloworld-go
  5.   namespace: default
  6. spec:
  7.   template:
  8.     metadata:
  9.       annotations:
  10.         autoscaling.knative.dev/target: "50"

Concurrency target - Global (ConfigMap)

  1. apiVersion: v1
  2. kind: ConfigMap
  3. metadata:
  4.  name: config-autoscaler
  5.  namespace: knative-serving
  6. data:
  7.  container-concurrency-target-default: "200"

Concurrency target - Container Global (Operator)

  1. apiVersion: operator.knative.dev/v1alpha1
  2. kind: KnativeServing
  3. metadata:
  4.   name: knative-serving
  5. spec:
  6.   config:
  7.     autoscaler:
  8.       container-concurrency-target-default: "200"
