Functions ¶
func NewLimitRanger ¶
func NewLimitRanger(actions LimitRangerActions) (admission.Interface, error)
NewLimitRanger returns an object that enforces limits based on the supplied limit function
func PersistentVolumeClaimLimitFunc ¶
func PersistentVolumeClaimLimitFunc(limitRange *api.LimitRange, pvc *api.PersistentVolumeClaim) error
PersistentVolumeClaimLimitFunc enforces storage limits for PVCs. Users request storage via pvc.Spec.Resources.Requests. Min/Max is enforced by an admin with LimitRange. Claims will not be modified with default values because storage is a required part of pvc.Spec. All storage enforced values *only* apply to pvc.Spec.Resources.Requests.
func PodLimitFunc ¶
func PodLimitFunc(limitRange *api.LimitRange, pod *api.Pod) error
PodLimitFunc enforces resource requirements enumerated by the pod against the specified LimitRange. The pod may be modified to apply default resource requirements if not specified, and enumerated on the LimitRange
Types ¶
type DefaultLimitRangerActions ¶
type DefaultLimitRangerActions struct{}
DefaultLimitRangerActions is the default implementation of LimitRangerActions.
func (*DefaultLimitRangerActions) Limit ¶
func (d *DefaultLimitRangerActions) Limit(limitRange *api.LimitRange, resourceName string, obj runtime.Object) error
Limit enforces resource requirements of incoming resources against enumerated constraints on the LimitRange. It may modify the incoming object to apply default resource requirements if not specified, and enumerated on the LimitRange
func (*DefaultLimitRangerActions) SupportsAttributes ¶
func (d *DefaultLimitRangerActions) SupportsAttributes(a admission.Attributes) bool
SupportsAttributes ignores all calls that do not deal with pod resources or storage requests (PVCs). Also ignores any call that has a subresource defined.
func (*DefaultLimitRangerActions) SupportsLimit ¶
func (d *DefaultLimitRangerActions) SupportsLimit(limitRange *api.LimitRange) bool
SupportsLimit always returns true.
type LimitRangerActions ¶
type LimitRangerActions interface {
// Limit is a pluggable function to enforce limits on the object.
Limit(limitRange *api.LimitRange, kind string, obj runtime.Object) error
// SupportsAttributes is a pluggable function to allow overridding what resources the limitranger
// supports.
SupportsAttributes(attr admission.Attributes) bool
// SupportsLimit is a pluggable function to allow ignoring limits that should not be applied
// for any reason.
SupportsLimit(limitRange *api.LimitRange) bool
}
