Types

type ConfigGenerator

type ConfigGenerator interface {
	// BuildListeners returns the list of inbound/outbound listeners for the given proxy. This is the LDS output
	// Internally, the computation will be optimized to ensure that listeners are computed only
	// once and shared across multiple invocations of this function.
	BuildListeners(node *model.Proxy, push *model.PushContext) []*listener.Listener

	// BuildClusters returns the list of clusters for the given proxy. This is the CDS output
	BuildClusters(node *model.Proxy, req *model.PushRequest) ([]*discovery.Resource, model.XdsLogDetails)

	// BuildDeltaClusters returns both a list of resources that need to be pushed for a given proxy and a list of resources
	// that have been deleted and should be removed from a given proxy. This is Delta CDS output.
	BuildDeltaClusters(proxy *model.Proxy, updates *model.PushRequest,
		watched *model.WatchedResource) ([]*discovery.Resource, []string, model.XdsLogDetails, bool)

	// BuildHTTPRoutes returns the list of HTTP routes for the given proxy. This is the RDS output
	BuildHTTPRoutes(node *model.Proxy, req *model.PushRequest, routeNames []string) ([]*discovery.Resource, model.XdsLogDetails)

	// BuildNameTable returns list of hostnames and the associated IPs
	BuildNameTable(node *model.Proxy, push *model.PushContext) *dnsProto.NameTable

	// BuildExtensionConfiguration returns the list of extension configuration for the given proxy and list of names. This is the ECDS output.
	BuildExtensionConfiguration(node *model.Proxy, push *model.PushContext, extensionConfigNames []string,
		pullSecrets map[string][]byte) []*core.TypedExtensionConfig

	// MeshConfigChanged is invoked when mesh config is changed, giving a chance to rebuild any cached config.
	MeshConfigChanged(mesh *meshconfig.MeshConfig)
}

ConfigGenerator represents the interfaces to be implemented by code that generates xDS responses

func NewConfigGenerator

func NewConfigGenerator(cache model.XdsCache) ConfigGenerator

NewConfigGenerator creates a new instance of the dataplane configuration generator
