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.
