Variables

var (
	ClusterResourceQuotaKind = "ClusterResourceQuota"

	LabelClusterResourceQuotaAutoUpdate = "clusterresourcequota.quota.kubezoo.io/autoupdate"
)

var DefaultRetry = wait.Backoff{
	Steps:    5,
	Duration: 10 * time.Millisecond,
	Factor:   1.0,
	Jitter:   0.1,
}

DefaultRetry is the recommended retry for a conflict where multiple clients are making changes to the same resource.

Types

	// contains filtered or unexported fields
}

func NewAdmission

func NewAdmission(ctx context.Context, client client.Client) *Admission

func (*Admission) Handle

func (a *Admission) Handle(ctx context.Context, req admission.Request) admission.Response

func (*Admission) InjectDecoder

func (a *Admission) InjectDecoder(d *admission.Decoder) error

InjectDecoder injects the decoder into a validatingHandler.

func (*Admission) InjectLogger

func (a *Admission) InjectLogger(logger logr.Logger) error

type ClusterResourceQuotaReconciler

ClusterResourceQuotaReconciler reconciles a ClusterResourceQuota object

func (*ClusterResourceQuotaReconciler) Reconcile

func (r *ClusterResourceQuotaReconciler) 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 ClusterResourceQuota 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@v0.13.0/pkg/reconcile

func (*ClusterResourceQuotaReconciler) SetupWithManager

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

SetupWithManager sets up the controller with the Manager.

type Updater

type Updater interface {
	Update(ctx context.Context, obj client.Object, opts ...client.UpdateOption) error
}
