Overview

Package definitions provides type definitions, parsing, marshaling and validation for Kubernetes resources used by Skipper.

const (
	ServiceBackend = eskip.LBBackend + 1 + iota
)

adding Kubernetes specific backend types here. To be discussed. The main reason is to differentiate between service and external, in a way where we can also use the current global option to decide whether the service should then be converted to LB. Or shall we expect the route group already contain the pod endpoints, and ignore the global option for skipper? --> As CRD we have to lookup endpoints ourselves, maybe via kube.go
