The number of authorization server replicas for an AuthServer can be specified under spec.replicas.
Furthermore, AuthServer implements the scale subresource. That means you can scale it scale an AuthServer with existing tooling. For example:
kubectl scale authserver authserver-sample --replicas=3
The resource of the authorization server and Redis Deployments can be configured under spec.resources and spec.redisResources respectively. See the API reference for details.
