Constants

const (
	// MaxDisruptedPodSize is the max size of PodDisruptionBudgetStatus.DisruptedPods. API server eviction
	// subresource handler will refuse to evict pods covered by the corresponding PDB
	// if the size of the map exceeds this value. It means a large number of
	// evictions have been approved by the API server but not noticed by the PDB controller yet.
	// This situation should self-correct because the PDB controller removes
	// entries from the map automatically after the PDB DeletionTimeout regardless.
	MaxDisruptedPodSize = 2000

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

type BindingREST struct {
	// contains filtered or unexported fields
}

BindingREST implements the REST endpoint for binding pods to nodes when etcd is in use.

func (*BindingREST) Create

func (r *BindingREST) Create(ctx context.Context, name string, obj runtime.Object, createValidation rest.ValidateObjectFunc, options *metav1.CreateOptions) (out runtime.Object, err error)

Create ensures a pod is bound to a specific host.

func (*BindingREST) NamespaceScoped

func (r *BindingREST) NamespaceScoped() bool

NamespaceScoped fulfill rest.Scoper

func (*BindingREST) New

func (r *BindingREST) New() runtime.Object

New creates a new binding resource

	PortForward         *podrest.PortForwardREST
}

PodStorage includes storage for pods and all sub resources

func NewStorage

func NewStorage(optsGetter generic.RESTOptionsGetter, k client.ConnectionInfoGetter, proxyTransport http.RoundTripper, podDisruptionBudgetClient policyclient.PodDisruptionBudgetsGetter) (PodStorage, error)

NewStorage returns a RESTStorage object that will work against pods.

type REST

type REST struct {
	*genericregistry.Store

}

REST implements a RESTStorage for pods

func (*REST) Categories

func (r *REST) Categories() []string

Categories implements the CategoriesProvider interface. Returns a list of categories a resource is part of.

func (*REST) ResourceLocation

ShortNames implements the ShortNamesProvider interface. Returns a list of short names for a resource.

type StatusREST

type StatusREST struct {
	// contains filtered or unexported fields
