Functions

func GetHostPort

func GetHostPort(name, addr string) (host string, port string, err error)

GetHostPort separates out the host and port portions of an address. The host portion may be a name, IPv4 address, or IPv6 address (with square brackets).

func RunProxy

func RunProxy(config *meshconfig.ProxyConfig, node string, epoch int, configFname string, doneChan chan error,
	outWriter io.Writer, errWriter io.Writer) (*os.Process, error)

RunProxy will run sidecar with a v2 config generated from template according with the config. The doneChan will be notified if the envoy process dies. The returned process can be killed by the caller to terminate the proxy.

func StoreHostPort

func StoreHostPort(host, port, field string, opts map[string]interface{})

StoreHostPort encodes the host and port as key/value pair strings in the provided map.

func WriteBootstrap

func WriteBootstrap(config *meshconfig.ProxyConfig, node string, epoch int, pilotSAN []string, opts map[string]interface{}) (string, error)

WriteBootstrap generates an envoy config based on config and epoch, and returns the filename. TODO: in v2 some of the LDS ports (port, http_port) should be configured in the bootstrap.
