Types

type IndexedResources

type IndexedResources struct {
	// Index is a map of typeURL => resourceName => resource
	Index map[string]map[string]proto.Message

	// ChildIndex is a map of typeURL => parentResourceName => list of
	// childResourceNames. This only applies if the child and parent do not
	// share a name.
	ChildIndex map[string]map[string][]string
}

func EmptyIndexedResources

func EmptyIndexedResources() *IndexedResources

type PluginConfiguration

type PluginConfiguration struct {
	// ServiceConfigs is a mapping from service names to the data Envoy plugins
	// need to override the default Envoy configurations.
	ServiceConfigs map[api.CompoundServiceName]ServiceConfig

	// SNIToServiceName is a mapping from SNIs to service names. This allows
	// Envoy plugins to easily convert from an SNI Envoy resource name to the
	// associated service's CompoundServiceName
	SNIToServiceName map[string]api.CompoundServiceName

	// EnvoyIDToServiceName is a mapping from EnvoyIDs to service names. This allows
	// Envoy plugins to easily convert from an EnvoyID Envoy resource name to the
	// associated service's CompoundServiceName
	EnvoyIDToServiceName map[string]api.CompoundServiceName

	// Kind is mode the local Envoy proxy is running in. For now, only
	// terminating gateways are supported.
	Kind api.ServiceKind
}

PluginConfiguration is passed into Envoy plugins. It should depend on the API client rather than the structs package because the API client is meant to be public.

func MakePluginConfiguration

func MakePluginConfiguration(cfgSnap *proxycfg.ConfigSnapshot) PluginConfiguration

MakePluginConfiguration generates the configuration that will be sent to Envoy plugins.

type ServiceConfig

type ServiceConfig struct {
	// Kind identifies the final proxy kind that will make the request to the
	// destination service.
	Kind api.ServiceKind
	Meta map[string]string
}
