Functions

func Add

func Add(mgr manager.Manager) error

Add creates a new DaemonSet Controller and adds it to the Manager. The Manager will set fields on the Controller and Start it when the Manager is Started.

func Match

func Match(ds *ketiv1.DaemonSet, history *ketiv1.ControllerRevision) (bool, error)

Match check if the given DaemonSet's template matches the template stored in the given history.

func NewPod

func NewPod(ds *ketiv1.DaemonSet, nodeName string) *ketiv1.Pod

NewPod creates a new pod

func Predicates

func Predicates(pod *ketiv1.Pod, nodeInfo *schedulernodeinfo.NodeInfo) (bool, []predicates.PredicateFailureReason, error)

Predicates checks if a DaemonSet's pod can be scheduled on a node using GeneralPredicates and PodToleratesNodeTaints predicate

Types

type ReconcileDaemonSet

type ReconcileDaemonSet struct {
	KetiClient migration.MigrationV1Interface
	KubeClient kubeclient.Interface
	// contains filtered or unexported fields
}

ReconcileDaemonSet reconciles a DaemonSet object

func (*ReconcileDaemonSet) Reconcile

func (r *ReconcileDaemonSet) Reconcile(request reconcile.Request) (reconcile.Result, error)

Reconcile reads that state of the cluster for a DaemonSet object and makes changes based on the state read and what is in the DaemonSet.Spec TODO(user): Modify this Reconcile function to implement your Controller logic. This example creates a Pod as an example Note: The Controller will requeue the Request to be processed again if the returned error is non-nil or Result.Requeue is true, otherwise upon completion it will remove the work from the queue.
