= Minimum scale bounds
|
|
|
|
The minimum number of replicas that can serve an application is determined by the `min-scale` annotation. If scale to zero is not enabled, the `min-scale` value defaults to `1`.
|
|
|
|
The `min-scale` value defaults to `0` replicas if the following conditions are met:
|
|
|
|
* The `min-scale` annotation is not set
|
|
* Scaling to zero is enabled
|
|
* The class `KPA` is used
|
|
