Types

type PolicyReconciler

type PolicyReconciler struct {
	client.Client
	Scheme           *runtime.Scheme
	TrackerNamespace string
	TrackerName      string
}

PolicyReconciler is the main controller for the Tracker Policy CRD. It is responsible for updating the Tracker DaemonSet whenever a change is detected in a TrackerPolicy object.

func (*PolicyReconciler) Reconcile

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

Reconcile is where the reconciliation logic resides. Every time a change is detected in a v1beta1.Policy object, this function will be called. It will update the Tracker DaemonSet, so that the Tracker pods will be restarted with the new policy. It does this by adding a timestamp annotation to the pod template, so that the daemonset controller will rollout a new daemonset ("restarting" the daemonset).

func (*PolicyReconciler) SetupWithManager

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

SetupWithManager is responsible for connecting the PolicyReconciler to the main controller manager. It tells the manager that for changes in v1beta1Policy objects, the PolicyReconciler should be invoked.
