Functions

func NewConfigServiceClient

func NewConfigServiceClient(opts Options) (client.Client, error)

NewConfigServiceClient returns a ConfigServiceClient.

Types

type Cluster

type Cluster interface {
	Zone() string
	SetZone(z string) Cluster

	Endpoints() []string
	SetEndpoints(endpoints []string) Cluster

	KeepAliveOptions() KeepAliveOptions
	SetKeepAliveOptions(value KeepAliveOptions) Cluster

	TLSOptions() TLSOptions
	SetTLSOptions(TLSOptions) Cluster
}

Cluster defines the configuration for a etcd cluster.

func NewCluster

func NewCluster() Cluster

NewCluster creates a Cluster.

type ClusterConfig

type ClusterConfig struct {
	Zone      string           `yaml:"zone"`
	Endpoints []string         `yaml:"endpoints"`
	KeepAlive *keepAliveConfig `yaml:"keepAlive"`
	TLS       *TLSConfig       `yaml:"tls"`
}

ClusterConfig is the config for a zoned etcd cluster.

func (ClusterConfig) NewCluster

func (c ClusterConfig) NewCluster() Cluster

NewCluster creates a new Cluster.

type Configuration

type Configuration struct {
	Zone              string                 `yaml:"zone"`
	Env               string                 `yaml:"env"`
	Service           string                 `yaml:"service" validate:"nonzero"`
	CacheDir          string                 `yaml:"cacheDir"`
	ETCDClusters      []ClusterConfig        `yaml:"etcdClusters"`
	SDConfig          services.Configuration `yaml:"m3sd"`
	WatchWithRevision int64                  `yaml:"watchWithRevision"`
}

Configuration is for config service client.

func (Configuration) NewClient

func (cfg Configuration) NewClient(iopts instrument.Options) (client.Client, error)

NewClient creates a new config service client.

func (Configuration) NewOptions

func (cfg Configuration) NewOptions() Options

NewOptions returns a new Options.

type KeepAliveOptions

type KeepAliveOptions interface {
	// KeepAliveEnabled determines whether keepAlives are enabled.
	KeepAliveEnabled() bool

	// SetKeepAliveEnabled sets whether keepAlives are enabled.
	SetKeepAliveEnabled(value bool) KeepAliveOptions

	// KeepAlivePeriod is the duration of time after which if the client doesn't see
	// any activity the client pings the server to see if transport is alive.
	KeepAlivePeriod() time.Duration

	// SetKeepAlivePeriod sets the duration of time after which if the client doesn't see
	// any activity the client pings the server to see if transport is alive.
	SetKeepAlivePeriod(value time.Duration) KeepAliveOptions

	// KeepAlivePeriodMaxJitter is used to add some jittering to keep alive period
	// to avoid a large number of clients all sending keepalive probes at the
	// same time.
	KeepAlivePeriodMaxJitter() time.Duration

	// SetKeepAlivePeriodMaxJitter sets the maximum jittering to keep alive period
	// to avoid a large number of clients all sending keepalive probes at the
	// same time.
	SetKeepAlivePeriodMaxJitter(value time.Duration) KeepAliveOptions

	// KeepAliveTimeout is the time that the client waits for a response for the
	// keep-alive probe. If the response is not received in this time, the connection is closed.
	KeepAliveTimeout() time.Duration

	// SetKeepAliveTimeout sets the time that the client waits for a response for the
	// keep-alive probe. If the response is not received in this time, the connection is closed.
	SetKeepAliveTimeout(value time.Duration) KeepAliveOptions
}

KeepAliveOptions provide a set of client-side keepAlive options.

func NewKeepAliveOptions

func NewKeepAliveOptions() KeepAliveOptions

NewKeepAliveOptions provide a set of keepAlive options.
