Types ¶
type ConfigMapLock ¶ added in v1.7.0

	// ConfigMapMeta should contain a Name and a Namespace of an
	// ConfigMapMeta object that the Leadercmlector will attempt to lead.
	ConfigMapMeta metav1.ObjectMeta
	Client        corev1client.ConfigMapsGetter

func (*ConfigMapLock) Update ¶ added in v1.7.0
func (cml *ConfigMapLock) Update(ler LeaderElectionRecord) error
Update will update and existing annotation on a given resource.
type EndpointsLock ¶
type EndpointsLock struct {
	// EndpointsMeta should contain a Name and a Namespace of an
	// Endpoints object that the LeaderElector will attempt to lead.
	EndpointsMeta metav1.ObjectMeta
	Client        corev1client.EndpointsGetter
	LockConfig    ResourceLockConfig
	// contains filtered or unexported fields
}
    func (*EndpointsLock) Create ¶
func (el *EndpointsLock) Create(ler LeaderElectionRecord) error
Create attempts to create a LeaderElectionRecord annotation
func (*EndpointsLock) Describe ¶
func (el *EndpointsLock) Describe() string
Describe is used to convert details on current resource lock into a string
func (*EndpointsLock) Get ¶
func (el *EndpointsLock) Get() (*LeaderElectionRecord, error)
Get returns the election record from a Endpoints Annotation
func (*EndpointsLock) Identity ¶
func (el *EndpointsLock) Identity() string
returns the Identity of the lock
func (*EndpointsLock) RecordEvent ¶
func (el *EndpointsLock) RecordEvent(s string)
RecordEvent in leader election while adding meta-data
func (*EndpointsLock) Update ¶
func (el *EndpointsLock) Update(ler LeaderElectionRecord) error
Update will update and existing annotation on a given resource.
type Interface ¶
type Interface interface {
	// Get returns the LeaderElectionRecord
	Get() (*LeaderElectionRecord, error)
	// Create attempts to create a LeaderElectionRecord
	Create(ler LeaderElectionRecord) error
	// Update will update and existing LeaderElectionRecord
	Update(ler LeaderElectionRecord) error
	// RecordEvent is used to record events
	RecordEvent(string)
	// Identity will return the locks Identity
	Identity() string
	// Describe is used to convert details on current resource lock
	// into a string
	Describe() string
}
    Interface offers a common interface for locking on arbitrary resources used in leader election. The Interface is used to hide the details on specific implementations in order to allow them to change over time. This interface is strictly for use by the leaderelection code.
type LeaderElectionRecord ¶
type LeaderElectionRecord struct {
	HolderIdentity       string      `json:"holderIdentity"`
	LeaseDurationSeconds int         `json:"leaseDurationSeconds"`
	AcquireTime          metav1.Time `json:"acquireTime"`
	RenewTime            metav1.Time `json:"renewTime"`
	LeaderTransitions    int         `json:"leaderTransitions"`
}
    LeaderElectionRecord is the record that is stored in the leader election annotation. This information should be used for observational purposes only and could be replaced with a random string (e.g. UUID) with only slight modification of this code. TODO(mikedanese): this should potentially be versioned
type ResourceLockConfig ¶
type ResourceLockConfig struct {
	Identity      string
	EventRecorder record.EventRecorder
}
    ResourceLockConfig common data that exists across different resource locks
