Types

type ConfigOKCondition

type ConfigOKCondition interface {
	// Set sets the Message, Reason, and Status of the condition
	Set(message, reason string, status apiv1.ConditionStatus)
	// SetFailSyncCondition sets the condition for when syncing Kubelet config fails
	SetFailSyncCondition(reason string)
	// ClearFailSyncCondition clears the overlay from SetFailSyncCondition
	ClearFailSyncCondition()
	// Sync patches the current condition into the Node identified by `nodeName`
	Sync(client clientset.Interface, nodeName string)
}

ConfigOKCondition represents a ConfigOK NodeCondition

func NewConfigOKCondition

func NewConfigOKCondition() ConfigOKCondition

NewConfigOKCondition returns a new ConfigOKCondition
