Functions

func CanonicalService

func CanonicalService(labels map[string]string, workloadName string) (string, string)

CanonicalService returns the values of the following labels from the supplied map: - service.istio.io/canonical-name - service.istio.io/canonical-revision

If the labels are not in the map, a set of fallbacks are checked. For canonical name, `app.kubernetes.io/name` is checked, then `app`, evenutually falling back to the supplied `workloadName`. For canonical revision, `app.kubernetes.io/version` is checked, followed by `version` and finally defaulting to the literal value of `"latest"`.

func HasCanonicalServiceName

func HasCanonicalServiceName(labels map[string]string) bool

func HasCanonicalServiceRevision

func HasCanonicalServiceRevision(labels map[string]string) bool

func WorkloadNameFromWorkloadEntry

func WorkloadNameFromWorkloadEntry(name string, annos map[string]string, labels map[string]string) string

WorkloadNameFromWorkloadEntry derives the workload name from a WorkloadEntry
