}

GoodnightDeploymentReconciler reconciles a GoodnightDeployment object

func (*GoodnightDeploymentReconciler) EnterSandman

func (r *GoodnightDeploymentReconciler) EnterSandman(ctx context.Context, s SleepyDeployment) error

func (*GoodnightDeploymentReconciler) LoadDeployments

func (r *GoodnightDeploymentReconciler) LoadDeployments(ctx context.Context)

func (*GoodnightDeploymentReconciler) Monitor

func (r *GoodnightDeploymentReconciler) Monitor(ctx context.Context)

func (*GoodnightDeploymentReconciler) Reconcile

func (r *GoodnightDeploymentReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, 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. TODO(user): Modify the Reconcile function to compare the state specified by the GoodnightDeployment object against the actual cluster state, and then perform operations to make the cluster state reflect the state specified by the user.

For more details, check Reconcile and its Result here: - https://pkg.go.dev/sigs.k8s.io/controller-runtime@v0.19.0/pkg/reconcile

func (*GoodnightDeploymentReconciler) SetupWithManager

SetupWithManager sets up the controller with the Manager.
