Functions

func MakeVirtualService

func MakeVirtualService(claims []*v1alpha1.RouteClaim, routes []*v1alpha1.Route) (*networking.VirtualService, error)

MakeVirtualService creates a VirtualService from a Route object.

Example

package main

import (
	"fmt"

	"github.com/google/kf/pkg/apis/kf/v1alpha1"
	"github.com/google/kf/pkg/reconciler/route/resources"
)

func makeRouteSpecFields(host, domain, path string) v1alpha1.RouteSpecFields {
	return v1alpha1.RouteSpecFields{
		Hostname: host,
		Domain:   domain,
		Path:     path,
	}
}

func makeRoute(host, domain, path string) *v1alpha1.Route {
	return &v1alpha1.Route{
		Spec: v1alpha1.RouteSpec{
			RouteSpecFields: makeRouteSpecFields(host, domain, path),
		},
	}
}

func makeRouteClaim(host, domain, path string) *v1alpha1.RouteClaim {
	return &v1alpha1.RouteClaim{
		Spec: v1alpha1.RouteClaimSpec{
			RouteSpecFields: makeRouteSpecFields(host, domain, path),
		},
	}
}

func main() {
	claims := []*v1alpha1.RouteClaim{
		makeRouteClaim("some-host", "example.com/", ""),
	}

	routes := []*v1alpha1.Route{
		makeRoute("some-host", "example.com/", ""),
		makeRoute("some-host", "example.com/", "/some-path-1"),
		makeRoute("some-host", "example.com/", "/some-path-2"),
	}

	vs, err := resources.MakeVirtualService(claims, routes)
	if err != nil {
		panic(err)
	}

	for i, h := range vs.Spec.HTTP {
		fmt.Printf("Regex %d: %s\n", i, h.Match[0].URI.Regex)
	}

}

Output:

Regex 0: ^(/.*)?
Regex 1: ^/some-path-1(/.*)?
Regex 2: ^/some-path-2(/.*)?

func MakeVirtualServiceLabels

func MakeVirtualServiceLabels(spec v1alpha1.RouteSpecFields) map[string]string

MakeVirtualServiceLabels creates Labels that can be used to tie a VirtualService to a Route.
