Overview ¶
Package envoy contains a configuration writer for v2 YAML config. To avoid a dependncy on a YAML library, we generate the YAML using the text/template package.

Functions ¶
func Clustername ¶
Clustername returns the name of the CDS cluster for this service.
func ConfigSource ¶
func ConfigSource(cluster string) *core.ConfigSource
ConfigSource returns a *core.ConfigSource for cluster.
func Hashname ¶
Hashname takes a lenth l and a varargs of strings s and returns a string whose length which does not exceed l. Internally s is joined with strings.Join(s, "/"). If the combined length exceeds l then hashname truncates each element in s, starting from the end using a hash derived from the contents of s (not the current element). This process continues until the length of s does not exceed l, or all elements have been truncated. In which case, the entire string is replaced with a hash not exceeding the length of l.
func RouteCluster ¶
func RouteCluster(service *dag.Service) route.Route_Route
RouteCluster returns a route.Route_Route for a single service.
func RouteRoute ¶
func RouteRoute(services []*dag.Service) route.Route_Route
RouteRoute returns a route.Route_Route for the services supplied. If len(services) is greater than one, the route's action will be a weighted cluster.
func TLSInspector ¶
func TLSInspector() listener.ListenerFilter
TLSInspector returns a new TLS inspector listener filter.
func UpstreamTLSContext ¶
func UpstreamTLSContext() *auth.UpstreamTlsContext
UpstreamTLSContext creates an ALPN h2 enabled TLS Context.
func WeightedClusters ¶
func WeightedClusters(services []*dag.Service) *route.WeightedCluster
WeightedClusters returns a route.WeightedCluster for multiple services.
Types ¶
type ConfigWriter ¶
type ConfigWriter struct {
// AdminAccessLogPath is the path to write the access log for the administration server.
// Defaults to /dev/null.
AdminAccessLogPath string
// AdminAddress is the TCP address that the administration server will listen on.
// Defaults to 127.0.0.1.
AdminAddress string
// AdminPort is the port that the administration server will listen on.
// Defaults to 9001.
AdminPort int
// StatsAddress is the address that the /stats path will listen on.
// Defaults to 0.0.0.0 and is only enabled if StatsdEnabled is true.
StatsAddress string
// StatsPort is the port that the /stats path will listen on.
// Defaults to 8002 and is only enabled if StatsdEnabled is true.
StatsPort int
// XDSAddress is the TCP address of the XDS management server. For JSON configurations
// this is the address of the v1 REST API server. For YAML configurations this is the
// address of the v2 gRPC management server.
// Defaults to 127.0.0.1.
XDSAddress string
// XDSRESTPort is the management server port that provides the v1 REST API.
// Defaults to 8000.
XDSRESTPort int
// XDSGRPCPort is the management server port that provides the v2 gRPC API.
// Defaults to 8001.
XDSGRPCPort int
// StatsdEnabled enables metrics output via statsd
// Defaults to false.
StatsdEnabled bool
// StatsdAddress is the UDP address of the statsd endpoint
// Defaults to 127.0.0.1.
StatsdAddress string
// StatsdPort is port of the statsd endpoint
// Defaults to 9125.
StatsdPort int
}
A ConfigWriter knows how to write a bootstap Envoy configuration in YAML format.
