Autoscaling
The Knative Pod Autoscaler (KPA), provides fast, request-based autoscaling capabilities. To correctly configure autoscaling to zero for revisions, you must modify its parameters.
target defines how many concurrent requests are wanted at a given time (soft
limit) and is the recommended configuration for autoscaling in Knative.
The minScale and maxScale annotations can be used to configure the minimum
and maximum number of pods that can serve applications.
You can access autoscaling capabilities by using kn to modify Knative services
without editing YAML files directly.
Use the service create and service update commands with the appropriate
flags to configure the autoscaling behavior.
