type TrafficMap

type TrafficMap map[string]*Node

TrafficMap is a map of app Nodes, each optionally holding Edge data. Metadata is a general purpose map for holding any desired node or edge information. Each app node should have a unique namespace+workload. Note that it is feasible but likely unusual to have two nodes with the same name+version in the same namespace.

func NewTrafficMap

func NewTrafficMap() TrafficMap
