Types

type CLACache 

type CLACache interface {
	GetCLA(ctx context.Context, meshName, meshHash string, cluster envoy_common.Cluster, apiVersion envoy_common.APIVersion) (proto.Message, error)
}

type CircuitBreakerMap 

type CircuitBreakerMap map[ServiceName]*mesh_core.CircuitBreakerResource

type DataplaneMetadata 

type DataplaneMetadata struct {
	DataplaneTokenPath  string
	DataplaneToken      string
	DataplaneResource   *core_mesh.DataplaneResource
	ZoneIngressResource *core_mesh.ZoneIngressResource
	AdminPort           uint32
	DNSPort             uint32
	EmptyDNSPort        uint32
	DynamicMetadata     map[string]string
	ProxyType           mesh_proto.ProxyType

}

DataplaneMetadata represents environment-specific part of a dataplane configuration.

This information might change from one dataplane run to another and therefore it cannot be a part of Dataplane resource.

On start-up, a dataplane captures its effective configuration (that might come from a file, environment variables and command line options) and includes it into request for a bootstrap config. Control Plane can use this information to fill in node metadata in the bootstrap config. Envoy will include node metadata from the bootstrap config at least into the very first discovery request on every xDS stream. This way, xDS server will be able to use Envoy node metadata to generate xDS resources that depend on environment-specific configuration.

type DestinationMap 

type DestinationMap map[ServiceName]TagSelectorSet

DestinationMap holds a set of selectors for all reachable Dataplanes grouped by service name. DestinationMap is based on ServiceName and not on the OutboundInterface because TrafficRoute can introduce new service destinations that were not included in a outbound section. Policies that match on outbound connections also match by service destination name and not outbound interface for the same reason.
