Types

type Advertisement interface {
	// the service being advertised.
	ServiceID() ServiceID

	// sets the service being advertised.
	SetServiceID(service ServiceID) Advertisement

	// optional health function, return an error to indicate unhealthy.
	Health() func() error

	// sets the health function for the advertised instance.
	SetHealth(health func() error) Advertisement

	// PlacementInstance returns the placement instance associated with this advertisement, which
	// contains the ID of the instance advertising and all other relevant fields.
	PlacementInstance() placement.Instance

	// SetPlacementInstance sets the Instance that is advertising.
	SetPlacementInstance(p placement.Instance) Advertisement
}

Advertisement advertises the availability of a given instance of a service.

func NewAdvertisement

func NewAdvertisement() Advertisement

NewAdvertisement creates a new Advertisement.

type CampaignOptions

type CampaignOptions interface {
	// LeaderValue allows the user to override the value a campaign announces
	// (that is, the value an observer sees upon calling Leader()). This
	// defaults to the hostname of the caller.
	LeaderValue() string
	SetLeaderValue(v string) CampaignOptions
}

CampaignOptions provide the ability to override campaign defaults.

func NewCampaignOptions

func NewCampaignOptions() (CampaignOptions, error)

NewCampaignOptions returns an empty CampaignOptions.

type Configuration

type Configuration struct {
	InitTimeout *time.Duration `yaml:"initTimeout"`
}

Configuration is the config for service options.

func (Configuration) NewOptions

func (cfg Configuration) NewOptions() Options

NewOptions creates an Option.

type ElectionConfiguration

type ElectionConfiguration struct {
	LeaderTimeout *time.Duration `yaml:"leaderTimeout"`
	ResignTimeout *time.Duration `yaml:"resignTimeout"`
	TTLSeconds    *int           `yaml:"TTLSeconds"`
}

ElectionConfiguration is for configuring election timeouts and TTLs

func (ElectionConfiguration) NewOptions

func (cfg ElectionConfiguration) NewOptions() ElectionOptions

NewOptions creates an ElectionOptions.

type ElectionOptions

type ElectionOptions interface {
	// Duration after which a call to Leader() will timeout if no response
	// returned from etcd. Defaults to 30 seconds.
	LeaderTimeout() time.Duration
	SetLeaderTimeout(t time.Duration) ElectionOptions

	// Duration after which a call to Resign() will timeout if no response
	// returned from etcd. Defaults to 30 seconds.
	ResignTimeout() time.Duration
	SetResignTimeout(t time.Duration) ElectionOptions

	// TTL returns the TTL used for campaigns. By default (ttl == 0), etcd will
	// set the TTL to 60s.
	TTLSecs() int
	SetTTLSecs(ttl int) ElectionOptions
}

ElectionOptions configure specific election-scoped options.

func NewElectionOptions

func NewElectionOptions() ElectionOptions

type HeartbeatService interface {
	// Heartbeat sends heartbeat for a service instance with a ttl.
	Heartbeat(instance placement.Instance, ttl time.Duration) error

	// Get gets healthy instances for a service.
	Get() ([]string, error)

	// GetInstances returns a deserialized list of healthy Instances.

type LeaderService

type LeaderService interface {
	// Close closes the election service client entirely. No more campaigns can be
	// started and any outstanding campaigns are closed.
	Close() error

	// Campaign proposes that the caller become the leader for a specified
	// election, with its leadership being refreshed on an interval according to
	// the ElectionOptions the service was created with. It returns a read-only
	// channel of campaign status events that is closed when the user resigns
	// leadership or the campaign is invalidated due to background session
	// expiration (i.e. failing to refresh etcd leadership lease). The caller
	// MUST consume this channel until it is closed or risk goroutine leaks.
	// Users are encouraged to read the package docs of services/leader for
	// advice on proper usage and common gotchas.
	//
	// The leader will announce its hostname to observers unless opts is non-nil
	// and opts.LeaderValue() is non-empty.
	Campaign(electionID string, opts CampaignOptions) (<-chan campaign.Status, error)

	// Resign gives up leadership of a specified election if the caller is the
	// current leader (if the caller is not the leader an error is returned).
	Resign(electionID string) error

	// Leader returns the current leader of a specified election (if there is no
	// leader then leader.ErrNoLeader is returned).
	Leader(electionID string) (string, error)

	// Observe returns a channel on which leader updates for a specified election
	// will be returned. If no one is campaigning for the given election the call
	// will still succeed and the channel will receive its first update when an
	// election is started.
	Observe(electionID string) (<-chan string, error)
}

LeaderService provides access to etcd-backed leader elections.
