Functions

func FilterStageComparison added in v0.18.27 

func FilterStageComparison(a, b FilterStage) int

FilterStageComparison helps implement the sort.Interface Less function for use in other implementations of sort.Interface returns -1 if less than, 0 if equal, 1 if greater than It is not sufficient to return a Less bool because calling functions need to know if equal or greater when Less is false

Types

type ClusterGeneratorPlugin 

type ClusterGeneratorPlugin interface {
	Plugin
	GeneratedClusters(params Params) ([]*envoyapi.Cluster, error)
}

Currently only supported for TCP listeners, plan to change this in the future

type ListenerFilterPlugin 

type ListenerFilterPlugin interface {
	Plugin
	ProcessListenerFilter(params Params, in *v1.Listener) ([]StagedListenerFilter, error)
}

type ListenerPlugin 

type ListenerPlugin interface {

func (s StagedListenerFilterList) Swap(i, j int)

type UpstreamPlugin 

type UpstreamPlugin interface {
	Plugin

type WellKnownFilterStage added in v0.18.27 

type WellKnownFilterStage int

WellKnownFilterStages are represented by an integer that reflects their relative ordering 

const (
	FaultStage     WellKnownFilterStage = iota // Fault injection // First Filter Stage
	CorsStage                                  // Cors stage
	WafStage                                   // Web application firewall stage
	AuthNStage                                 // Authentication stage
	AuthZStage                                 // Authorization stage
	RateLimitStage                             // Rate limiting stage
	AcceptedStage                              // Request passed all the checks and will be forwarded upstream
	OutAuthStage                               // Add auth for the upstream (i.e. aws λ)
	RouteStage                                 // Request is going to upstream // Last Filter Stage
)

If new well known filter stages are added, they should be inserted in a position corresponding to their order
