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.
