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 setting a concurrency target, andrequests-per-second-target-default
for setting a requests-per-second (RPS) target. For more information, see the documentation on metrics. - Per-revision annotation key:
autoscaling.knative.dev/target
- Possible values: An integer (metric agnostic).
Default:
"100"
forcontainer-concurrency-target-default
, and"200"
forrequests-per-second-target-default
. There is no default value set for thetarget
annotation.- Concurrency target - Global (ConfigMap)
- Concurrency target - Container Global (Operator)
- Requests per second (RPS) target - Global (ConfigMap)
- Requests per second (RPS) target - Global (Operator)
