func GetControllerConfig

func GetControllerConfig(st *state.State) (controller.Config, error)

GetControllerConfig gets the controller config from a *State - it exists so we can test the manifold without a StateSuite.

func Manifold

func Manifold(config ManifoldConfig) dependency.Manifold

Manifold returns a dependency.Manifold that will run an HTTP server worker. The manifold outputs an *apiserverhttp.Mux, for other workers to register handlers against.

func NewTLSConfig

func NewTLSConfig(st *state.State, defaultSNI SNIGetterFunc, logger Logger) (*tls.Config, error)

NewTLSConfig returns the TLS configuration for the HTTP server to use based on controller configuration stored in the state database.

func NewWorkerShim

func NewWorkerShim(config Config) (worker.Worker, error)

NewWorkerShim calls through to NewWorker, and exists only to adapt to the signature of ManifoldConfig.NewWorker.

type Config

type Config struct {
	AgentName            string
	Clock                clock.Clock
	TLSConfig            *tls.Config
	Mux                  *apiserverhttp.Mux
	MuxShutdownWait      time.Duration
	LogDir               string
	Logger               Logger
	PrometheusRegisterer prometheus.Registerer
	Hub                  *pubsub.StructuredHub
	APIPort              int
	APIPortOpenDelay     time.Duration
	ControllerAPIPort    int
}

Config is the configuration required for running an API server worker.

func (Config) Validate

func (config Config) Validate() error

Validate validates the API server configuration.

type Logger

type Logger interface {
	Debugf(string, ...interface{})
	Errorf(string, ...interface{})
	Infof(string, ...interface{})
	Logf(loggo.Level, string, ...interface{})
	Warningf(string, ...interface{})
}

type ManifoldConfig

type ManifoldConfig struct {
	AuthorityName string
	HubName       string
	MuxName       string
	StateName     string

	// We don't use these in the worker, but we want to prevent the
	// httpserver from starting until they're running so that all of
	// their handlers are registered.
	RaftTransportName string
	APIServerName     string

	AgentName            string
	Clock                clock.Clock
	MuxShutdownWait      time.Duration
	LogDir               string
	PrometheusRegisterer prometheus.Registerer

	Logger Logger

	GetControllerConfig func(*state.State) (controller.Config, error)
	NewTLSConfig        func(*state.State, SNIGetterFunc, Logger) (*tls.Config, error)
	NewWorker           func(Config) (worker.Worker, error)
}

ManifoldConfig holds the information necessary to run an HTTP server in a dependency.Engine.

func (ManifoldConfig) Validate

func (config ManifoldConfig) Validate() error

Validate validates the manifold configuration.

type SNIGetterFunc

type SNIGetterFunc func(*tls.ClientHelloInfo) (*tls.Certificate, error)

type Worker

type Worker struct {
	// contains filtered or unexported fields
}

func NewWorker

func NewWorker(config Config) (*Worker, error)

NewWorker returns a new API server worker, with the given configuration.

func (*Worker) Kill

func (w *Worker) Kill()

Kill implements worker.Kill.

func (*Worker) Report

func (w *Worker) Report() map[string]interface{}

Report provides information for the engine report.

func (*Worker) URL

func (w *Worker) URL() string

URL returns the base URL of the HTTP server of the form https://ipaddr:port with no trailing slash.

func (*Worker) Wait

func (w *Worker) Wait() error

Wait implements worker.Wait.
