Constants

const (
	// DefaultLbType set to round robin
	DefaultLbType = networking.LoadBalancerSettings_ROUND_ROBIN
	// ManagementClusterHostname indicates the hostname used for building inbound clusters for management ports
	ManagementClusterHostname = "mgmtCluster"
)

const (

	// HTTPStatPrefix indicates envoy stat prefix for http listeners
	HTTPStatPrefix = "http"

	// RDSName is the name of route-discovery-service (RDS) cluster
	RDSName = "rds"

	// RDSHttpProxy is the special name for HTTP PROXY route
	RDSHttpProxy = "http_proxy"

	// VirtualListenerName is the name for traffic capture listener
	VirtualListenerName = "virtual"

	// WildcardAddress binds to all IP addresses
	WildcardAddress = "0.0.0.0"

)

Variables

var ALPNH2Only = []string{"h2"}

ALPNH2Only advertises that Proxy is going to use HTTP/2 when talking to the cluster.

var ALPNInMesh = []string{"istio"}

ALPNInMesh advertises that Proxy is going to talk to the in-mesh cluster. The custom "istio" value indicates in-mesh traffic and it's going to be used for routing decisions.

var ALPNInMeshH2 = []string{"istio", "h2"}

ALPNInMeshH2 advertises that Proxy is going to use HTTP/2 when talking to the in-mesh cluster. The custom "istio" value indicates in-mesh traffic and it's going to be used for routing decisions. Once Envoy supports client-side ALPN negotiation, this should be {"istio", "h2", "http/1.1"}.

var ListenersALPNProtocols = []string{"h2", "http/1.1"}

ListenersALPNProtocols denotes the the list of ALPN protocols that the listener should expose

Types

type ConfigGeneratorImpl

type ConfigGeneratorImpl struct {
	// List of plugins that modify code generated by this config generator
	Plugins []plugin.Plugin
}

func NewConfigGenerator

func NewConfigGenerator(plugins []plugin.Plugin) *ConfigGeneratorImpl

func (*ConfigGeneratorImpl) BuildClusters

func (configgen *ConfigGeneratorImpl) BuildClusters(env model.Environment, proxy model.Proxy) ([]*v2.Cluster, error)

BuildClusters returns the list of clusters for the given proxy. This is the CDS output For outbound: Cluster for each service/subset hostname or cidr with SNI set to service hostname Cluster type based on resolution For inbound (sidecar only): Cluster for each inbound endpoint port and for each service port

func (*ConfigGeneratorImpl) BuildListeners

func (configgen *ConfigGeneratorImpl) BuildListeners(env model.Environment, node model.Proxy) ([]*xdsapi.Listener, error)

BuildListeners produces a list of listeners and referenced clusters for all proxies

func (*ConfigGeneratorImpl) BuildRoutes

func (_ *ConfigGeneratorImpl) BuildRoutes(env model.Environment, node model.Proxy, routeName string) ([]*xdsapi.RouteConfiguration, error)

TODO

func (*ConfigGeneratorImpl) BuildSidecarOutboundHTTPRouteConfig

func (configgen *ConfigGeneratorImpl) BuildSidecarOutboundHTTPRouteConfig(env model.Environment, node model.Proxy,
	proxyInstances []*model.ServiceInstance, services []*model.Service, routeName string) *xdsapi.RouteConfiguration

BuildSidecarOutboundHTTPRouteConfig builds an outbound HTTP Route for sidecar. Based on port, will determine all virtual hosts that listen on the port.
