Types

type NodeSetReconciler 

type NodeSetReconciler struct {
	client.Client
	Scheme *runtime.Scheme

	ClientMap *clientmap.ClientMap
	// contains filtered or unexported fields
}

NodeSetReconciler reconciles a NodeSet object

func NewReconciler 

func NewReconciler(c client.Client, cm *clientmap.ClientMap) *NodeSetReconciler

func (*NodeSetReconciler) EnqueueNodeSetAfter 

func (r *NodeSetReconciler) EnqueueNodeSetAfter(nodeset *slinkyv1beta1.NodeSet, after time.Duration)

EnqueueNodeSetAfter schedules a reconcile of the NodeSet after the given delay. It uses the shared durationStore so that the next Reconcile result will have RequeueAfter set.

func (*NodeSetReconciler) NodeShouldRunDaemonPod 

func (r *NodeSetReconciler) NodeShouldRunDaemonPod(ctx context.Context, node *corev1.Node, nodeset *slinkyv1beta1.NodeSet) (bool, bool)

NodeShouldRunDaemonPod checks a set of preconditions against a (node,daemonset) and returns a summary. Returned booleans are:

  • shouldRun: Returns true when a daemonset should run on the node if a daemonset pod is not already running on that node.
  • shouldContinueRunning: Returns true when a daemonset should continue running on a node if a daemonset pod is already running on that node.

func (*NodeSetReconciler) Reconcile 

func (r *NodeSetReconciler) Reconcile(ctx context.Context, req ctrl.Request) (res ctrl.Result, retErr error)

Reconcile is part of the main kubernetes reconciliation loop which aims to move the current state of the cluster closer to the desired state.

func (*NodeSetReconciler) SetupWithManager 

func (r *NodeSetReconciler) SetupWithManager(mgr ctrl.Manager) error

SetupWithManager sets up the controller with the Manager.

func (*NodeSetReconciler) Sync 

func (r *NodeSetReconciler) Sync(ctx context.Context, req reconcile.Request) error

Sync implements control logic for synchronizing a NodeSet and its derived Pods.
