Functions

func GetNodeID

func GetNodeID(agent Agent) string

GetNodeID returns the envoy metadata ID for pilot's service discovery.

Types

type Agent

type Agent interface {
	io.Closer
	// GetConfig returns the ServiceEntry configuration for this agent.
	GetConfig() model.Config
	// GetAdminPort returns the Envoy administration port for this agent.
	GetAdminPort() int
	// GetPorts returns a list of port mappings between Envoy and the backend application.
	GetPorts() []*MappedPort
	// IsConfiguredForService indicates whether this agent has received configuration for communication with the given service.
	CheckConfiguredForService(target Agent) error
}

Agent is a wrapper around an Envoy proxy that has been configured for a particular backend Application.

type Factory

type Factory func(serviceName, version string, serviceManager *service.Manager, appFactory application.Factory, portMgr reserveport.PortManager) (Agent, error)

Factory is a function that manufactures Agent instances.

type MappedPort

type MappedPort struct {
	Name            string
	Protocol        model.Protocol
	ProxyPort       int
	ApplicationPort int
}

MappedPort provides a single port mapping between an Envoy proxy and its backend application.

func FindFirstPortForProtocol

func FindFirstPortForProtocol(a Agent, protocol model.Protocol) (*MappedPort, error)

FindFirstPortForProtocol is a utility method to simplify lookup of a port for a given protocol.

type PilotAgentFactory

type PilotAgentFactory struct {
	DiscoveryAddress *net.TCPAddr
	TmpDir           string
	EnvoyLogLevel    envoy.LogLevel
}

PilotAgentFactory is responsible for manufacturing agent.Agent instances which use Pilot for configuration.

func (*PilotAgentFactory) NewAgent

func (f *PilotAgentFactory) NewAgent(serviceName, version string, serviceManager *service.Manager, appFactory application.Factory,
	portMgr reserveport.PortManager) (Agent, error)

NewAgent is an agent.Factory function that creates new agent.Agent instances which use Pilot for configuration
