Functions

func IsDefaultDeny added in v1.3.0

Types

type Evaluator added in v1.4.0

type Evaluator interface {
	// Evaluate takes an operation and checks to see if quota constraints are satisfied.  It returns an error if they are not.
	// The default implementation process related operations in chunks when possible.
	Evaluate(a admission.Attributes) error
}

Evaluator is used to see if quota constraints are satisfied.

func NewQuotaEvaluator added in v1.4.0

func NewQuotaEvaluator(quotaAccessor QuotaAccessor, ignoredResources map[schema.GroupResource]struct{}, quotaRegistry quota.Registry, lockAcquisitionFunc func([]api.ResourceQuota) func(), config *resourcequotaapi.Configuration, workers int, stopCh <-chan struct{}) Evaluator

NewQuotaEvaluator configures an admission controller that can enforce quota constraints using the provided registry. The registry must have the capability to handle group/kinds that are persisted by the server this admission controller is intercepting

type QuotaAccessor added in v1.4.0

type QuotaAccessor interface {
	// UpdateQuotaStatus is called to persist final status.  This method should write to persistent storage.
	// An error indicates that write didn't complete successfully.
	UpdateQuotaStatus(newQuota *api.ResourceQuota) error

	// GetQuotas gets all possible quotas for a given namespace
	GetQuotas(namespace string) ([]api.ResourceQuota, error)
}

QuotaAccessor abstracts the get/set logic from the rest of the Evaluator. This could be a test stub, a straight passthrough, or most commonly a series of deconflicting caches.

type QuotaAdmission added in v1.9.0

type QuotaAdmission struct {
	*admission.Handler
	// contains filtered or unexported fields
}

QuotaAdmission implements an admission controller that can enforce quota constraints

func NewResourceQuota

func NewResourceQuota(config *resourcequotaapi.Configuration, numEvaluators int, stopCh <-chan struct{}) (*QuotaAdmission, error)

NewResourceQuota configures an admission controller that can enforce quota constraints using the provided registry. The registry must have the capability to handle group/kinds that are persisted by the server this admission controller is intercepting

func (*QuotaAdmission) SetQuotaConfiguration added in v1.9.0

func (*QuotaAdmission) Validate added in v1.9.0

func (a *QuotaAdmission) Validate(attr admission.Attributes) (err error)
