The files in this directory are organized as follows:
core/: the elements that are required for knative/serving to function,istio-ingress/: the configuration needed to plug in the istio ingress implementation,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 thecert-managercertificate implementation,monitoring/: an installable bundle of tooling for assorted observability functions,*.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.
