Functions

func Id

func Id(namespace, workload, app, version, service, graphType string) (id, nodeType string)

Types

type Edge

type Edge struct {
	Source   *Node
	Dest     *Node
	Metadata map[string]interface{} // app-specific data
}

func NewEdge

func NewEdge(source, dest *Node) Edge

type NamespaceInfo

type NamespaceInfo struct {
	Name     string
	Duration time.Duration
}

type Node

type Node struct {
	ID        string                 // unique identifier for the node
	NodeType  string                 // Node type
	Namespace string                 // Namespace
	Workload  string                 // Workload (deployment) name
	App       string                 // Workload app label value
	Version   string                 // Workload version label value
	Service   string                 // Service name
	Edges     []*Edge                // child nodes
	Metadata  map[string]interface{} // app-specific data
}

func NewNode

func NewNode(namespace, workload, app, version, service, graphType string) Node

func NewNodeExplicit

func NewNodeExplicit(id, namespace, workload, app, version, service, nodeType, graphType string) Node

func (*Node) AddEdge

func (s *Node) AddEdge(dest *Node) *Edge

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
