Constants

const DebugHandlerPath = "/debug/resource-dependency-graph"

DebugHandlerPath is the HTTP handler path for this debug handler.

Functions

func New

func New(logger logr.Logger, client client.Client) *graph

New creates a new graph interface for tracking resource dependencies.

func NewDebugHandler

func NewDebugHandler(graph *graph) http.HandlerFunc

NewDebugHandler creates a new HTTP handler for debugging the resource dependency graph.

Types

type Interface

type Interface interface {
	// Setup registers the event handler functions for the various resource types.
	Setup(ctx context.Context, c cache.Cache) error
	// HasVertex returns true when the given vertex exists in the graph.
	HasVertex(vertexType VertexType, vertexNamespace, vertexName string) bool
	// HasPathFrom returns true when there is a path from <from> to <to>.
	HasPathFrom(fromType VertexType, fromNamespace, fromName string, toType VertexType, toNamespace, toName string) bool
}

Interface is used to track resources dependencies.
