When kicking a managed EKS cluster using a yaml config file, what does desiredCapacity in ClusterConfig specify?

Question

I am a k8s and EKS noob. I'm trying to kick a cluster and keep meeting the desiredCapacity key. I just cannot find where it is documented.
Don't bother pointing to the schema, it's not described there.

This field is actually used by ASG; where it means your cluster will start by launching the desired capacity (# of EC2 instance), and ASG will monitor and replace any instance that has health issue to maintain the desired capacity for your cluster.
