package binding

import "k8s.io/kubernetes/pkg/registry/binding"

Package binding contains the middle layer logic for bindings. Bindings are objects containing instructions for how a pod ought to be bound to a host. This allows a registry object which supports this action (ApplyBinding) to be served through an apiserver.

Types ¶

type MockRegistry ¶

type MockRegistry struct {
	OnApplyBinding func(binding *api.Binding) error
}

MockRegistry can be used for testing.

func (MockRegistry) ApplyBinding ¶

func (mr MockRegistry) ApplyBinding(ctx api.Context, binding *api.Binding) error

type REST ¶

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

REST implements the RESTStorage interface for bindings. When bindings are written, it changes the location of the affected pods. This information is eventually reflected in the pod's CurrentState.Host field.

func NewREST ¶

func NewREST(bindingRegistry Registry) *REST

NewREST creates a new REST backed by the given bindingRegistry.

func (*REST) Create ¶

func (b *REST) Create(ctx api.Context, obj runtime.Object) (<-chan runtime.Object, error)

Create attempts to make the assignment indicated by the binding it recieves.

func (*REST) Delete ¶

func (*REST) Delete(ctx api.Context, id string) (<-chan runtime.Object, error)

Delete returns an error because bindings are write-only objects.

func (*REST) Get ¶

func (*REST) Get(ctx api.Context, id string) (runtime.Object, error)

Get returns an error because bindings are write-only objects.

func (*REST) List ¶

func (*REST) List(ctx api.Context, label, field labels.Selector) (runtime.Object, error)

List returns an error because bindings are write-only objects.

func (*REST) New ¶

func (*REST) New() runtime.Object

New returns a new binding object fit for having data unmarshalled into it.

func (*REST) Update ¶

func (b *REST) Update(ctx api.Context, obj runtime.Object) (<-chan runtime.Object, error)

Update returns an error-- this object may not be updated.

type Registry ¶

type Registry interface {
	// ApplyBinding should apply the binding. That is, it should actually
	// assign or place pod binding.PodID on machine binding.Host.
	ApplyBinding(ctx api.Context, binding *api.Binding) error
}

Registry contains the functions needed to support a BindingStorage.
