The files in this directory are organized as follows:

• core/: the elements that are required for knative/serving to function,
• hpa-autoscaling/: the configuration needed to extend the core with HPA-class autoscaling,
• namespace-wildcards/: the configuration needed to extend the core to provision wildcard certificates per-namespace,
• cert-manager/: the configuration needed to plug in the cert-manager certificate implementation,
• *.yaml: symlinks that form a particular "rendered view" of the knative/serving configuration.

The Core is complex enough that it further breaks down as follows:

• roles/: The [cluster] roles needed for the core controllers to function, or to plug knative/serving into standard Kubernetes RBAC constructs.
• configmaps/: The configmaps that are used to configure the core components.
• resources/: The serving resource definitions.
• webhooks/: The serving {mutating, validating} admission webhook configurations, and supporting resources.
• deployments/: The serving executable components and associated configuration resources.
