Types

type CompletedConfig 

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

func (CompletedConfig) New 

func (c CompletedConfig) New(name string) (*WebServer, error)

New creates a new server which logically combines the handling chain with the passed server. name is used to differentiate for logging. The handler chain in particular can be difficult as it starts delgating.

type Config 

type Config struct {
	GetViper func() *viper.Viper // If set, overrides params below
	Proto    Web

	GatewayOptions []grpc.GatewayOption
	GinMiddlewares []gin.HandlerFunc

	CORS *cors.Config

	TlsConfig *tls.Config

	ServiceRegistryBackend *consul.ServiceRegister
	ServiceResolverBackend *consul.ServiceResolver

	// BindAddress is the host name to use for bind (local internet) facing URLs (e.g. Loopback)
	// Will default to a value based on secure serving info and available ipv4 IPs.
	BindAddress string
	// ExternalAddress is the host name to use for external (public internet) facing URLs (e.g. Swagger)
	// Will default to a value based on secure serving info and available ipv4 IPs.
	ExternalAddress string
	// ShutdownDelayDuration allows to block shutdown for some time, e.g. until endpoints pointing to this API server
	// have converged on all node. During this time, the API server keeps serving, /healthz will return 200,
	// but /readyz will return failure.
	ShutdownDelayDuration time.Duration
}

func NewConfig 

func NewConfig() *Config

NewConfig returns a Config struct with the default values

func NewViperConfig added in v0.0.17 

func NewViperConfig(getViper func() *viper.Viper) *Config

NewViperConfig returns a Config struct with the global viper instance key representing a sub tree of this instance. NewViperConfig is case-insensitive for a key.

func (*Config) Complete 

func (c *Config) Complete() CompletedConfig

Complete fills in any fields not set that are required to have valid data and can be derived from other fields. If you're going to `ApplyOptions`, do that first. It's mutating the receiver.

type PostStartHookFunc 

type PostStartHookFunc func(ctx context.Context) error

PostStartHookFunc is a function that is called after the server has started. It must properly handle cases like:

  1. asynchronous start in multiple API server processes
  2. conflicts between the different processes all trying to perform the same action
  3. partially complete work (API server crashes while running your hook)
  4. API server access **BEFORE** your hook has completed

Think of it like a mini-controller that is super privileged and gets to run in-process If you use this feature, tag @deads2k on github who has promised to review code for anyone's PostStartHook until it becomes easier to use.

type PostStartHookProvider 

type PostStartHookProvider interface {
	PostStartHook() (string, PostStartHookFunc, error)
}

PostStartHookProvider is an interface in addition to provide a post start hook for the api server

type PreShutdownHookFunc 

type PreShutdownHookFunc func() error

PreShutdownHookFunc is a function that can be added to the shutdown logic.

	// ShutdownDelayDuration allows to block shutdown for some time, e.g. until endpoints pointing to this API server
	// have converged on all node. During this time, the API server keeps serving, /healthz will return 200,
	// but /readyz will return failure.
	ShutdownDelayDuration time.Duration

}

func (*WebServer) AddBootSequenceHealthChecks 

func (s *WebServer) AddBootSequenceHealthChecks(checks ...healthz.HealthCheck) error

AddBootSequenceHealthChecks adds health checks to the old healthz endpoint (for backwards compatibility reasons) as well as livez and readyz. The livez grace period is defined by the value of the command-line flag --livez-grace-period; before the grace period elapses, the livez health checks will default to healthy. One may want to set a grace period in order to prevent the kubelet from restarting the kube-apiserver due to long-ish boot sequences. Readyz health checks, on the other hand, have no grace period, since readyz should fail until boot fully completes.

func (*WebServer) AddHealthChecks 

func (s *WebServer) AddHealthChecks(checks ...healthz.HealthCheck) error

AddHealthChecks adds HealthCheck(s) to health endpoints (healthz, livez, readyz) but configures the liveness grace period to be zero, which means we expect this health check to immediately indicate that the apiserver is unhealthy.

AddPreShutdownHook allows you to add a PreShutdownHook.

func (*WebServer) AddPreShutdownHookOrDie 

func (s *WebServer) AddPreShutdownHookOrDie(name string, hook PreShutdownHookFunc)

AddPreShutdownHookOrDie allows you to add a PostStartHook, but dies on failure
