Types

type Filter

type Filter struct {
	// DiscoveryAddr is the address of the "real" discovery service whose responses will be filtered.
	DiscoveryAddr string

	// The filtering function to be used for processing discovery responses. If nil, Identity will be used.
	FilterFunc FilterFunc
}

Filter proxies requests to an Envoy discovery service (e.g. Pilot) and filters the responses.

func (*Filter) StreamAggregatedResources

func (p *Filter) StreamAggregatedResources(stream ads.AggregatedDiscoveryService_StreamAggregatedResourcesServer) error

StreamAggregatedResources implements the ADS interface.

type FilterFunc

type FilterFunc func(resp *xdsapi.DiscoveryResponse) (*xdsapi.DiscoveryResponse, error)
