Types ¶

type Master ¶

type Master string

Master is used to announce the current elected master.

func (Master) IsAnAPIObject ¶

func (Master) IsAnAPIObject()

IsAnAPIObject is used solely so we can work with the watch package. TODO: Either fix watch so this isn't necessary, or make this a real API Object. TODO: when it becomes clear how this package will be used, move these declarations to to the proper place.

type MasterElector ¶

type MasterElector interface {
	// RequestMaster makes the caller represented by 'id' enter into a master election for the
	// distributed lock defined by 'path'
	// The returned watch.Interface provides a stream of Master objects which
	// contain the current master.
	// Calling Stop on the returned interface relinquishes ownership (if currently possesed)
	// and removes the caller from the election
	Elect(path, id string) watch.Interface
}

MasterElector is an interface for services that can elect masters. Important Note: MasterElectors are not inter-operable, all participants in the election need to be

using the same underlying implementation of this interface for correct behavior.

func NewEtcdMasterElector ¶

func NewEtcdMasterElector(h tools.EtcdGetSet) MasterElector

NewEtcdMasterElector returns an implementation of election.MasterElector backed by etcd.
