func AddPortIfMissing ¶ Uses

func AddPortIfMissing(c *echo.Config, protocol protocol.Instance)

AddPortIfMissing adds a port for the given protocol if none was found.

func CallEcho ¶ Uses

func CallEcho(c *client.Instance, opts *echo.CallOptions, outboundPortSelector OutboundPortSelectorFunc) (client.ParsedResponses, error)

func CheckOutboundConfig ¶ Uses

func CheckOutboundConfig(source echo.Instance, target echo.Instance, port echo.Port, validator *structpath.Instance) error

CheckOutboundConfig checks the Envoy config dump for outbound configuration to the given target.

func FillInDefaults ¶ Uses

func FillInDefaults(ctx resource.Context, defaultDomain string, c *echo.Config) (err error)

func GetPortForProtocol ¶ Uses

func GetPortForProtocol(c *echo.Config, protocol protocol.Instance) *echo.Port

GetPortForProtocol returns the first port found with the given protocol, or nil if none was found.

func WaitForConfig ¶ Uses

func WaitForConfig(fetch ConfigFetchFunc, accept ConfigAcceptFunc, options ...retry.Option) error

type ConfigAcceptFunc ¶ Uses

type ConfigAcceptFunc func(*envoyAdmin.ConfigDump) (bool, error)

ConfigAcceptFunc evaluates the Envoy config dump and either accept/reject it. This is used by WaitForConfig to control the retry loop. If an error is returned, a retry will be attempted. Otherwise the loop is immediately terminated with an error if rejected or none if accepted.

func OutboundConfigAcceptFunc ¶ Uses

func OutboundConfigAcceptFunc(source echo.Instance, targets ...echo.Instance) ConfigAcceptFunc

OutboundConfigAcceptFunc returns a function that accepts Envoy configuration if it contains outbound configuration for all of the given instances.

type ConfigFetchFunc ¶ Uses

type ConfigFetchFunc func() (*envoyAdmin.ConfigDump, error)

ConfigFetchFunc retrieves the config dump from Envoy.

type OutboundPortSelectorFunc ¶ Uses

type OutboundPortSelectorFunc func(servicePort int) (int, error)

OutboundPortSelectorFunc is a function that selects the appropriate outbound port for sending requests to a target service.

var (
    // IdentityOutboundPortSelector is an OutboundPortSelectorFunc that always returns the original service port.
    IdentityOutboundPortSelector OutboundPortSelectorFunc = func(servicePort int) (int, error) {
        return servicePort, nil
    }
)
