Variables

var Strategy = podStrategy{api.Scheme, api.SimpleNameGenerator}

Strategy is the default logic that applies when creating and updating Pod objects via the REST API. TODO: Create other strategies for updating status, bindings, etc

Functions

func MatchPod

func MatchPod(label, field labels.Selector) generic.Matcher

MatchPod returns a generic matcher for a given label and field selector.

func PodStatusDecorator

func PodStatusDecorator(cache PodStatusGetter) rest.ObjectFunc

PodStatusDecorator returns a function that updates pod.Status based on the provided pod cache.

func PodStatusReset

func PodStatusReset(cache PodStatusGetter) rest.ObjectFunc

PodStatusReset returns a function that clears the pod cache when the object is deleted.

func PodToSelectableFields

func PodToSelectableFields(pod *api.Pod) labels.Set

PodToSelectableFields returns a label set that represents the object TODO: fields are not labels, and the validation rules for them do not apply.

func ResourceLocation

func ResourceLocation(getter ResourceGetter, ctx api.Context, id string) (string, error)

ResourceLocation returns a URL to which one can send traffic for the specified pod.

Types

type BasicBoundPodFactory

type BasicBoundPodFactory struct{}

func (*BasicBoundPodFactory) MakeBoundPod

func (b *BasicBoundPodFactory) MakeBoundPod(machine string, pod *api.Pod) (*api.BoundPod, error)

type BoundPodFactory

type BoundPodFactory interface {
	// Make a container object for a given pod, given the machine that the pod is running on.
	MakeBoundPod(machine string, pod *api.Pod) (*api.BoundPod, error)
}

type PodStatusGetter

type PodStatusGetter interface {
	GetPodStatus(namespace, name string) (*api.PodStatus, error)
	ClearPodStatus(namespace, name string)
}

PodStatusGetter is an interface used by Pods to fetch and retrieve status info.

type Registry

type Registry interface {
	// ListPods obtains a list of pods having labels which match selector.
	ListPods(ctx api.Context, selector labels.Selector) (*api.PodList, error)
	// Watch for new/changed/deleted pods
	WatchPods(ctx api.Context, label, field labels.Selector, resourceVersion string) (watch.Interface, error)
	// Get a specific pod
	GetPod(ctx api.Context, podID string) (*api.Pod, error)
	// Create a pod based on a specification.
	CreatePod(ctx api.Context, pod *api.Pod) error
	// Update an existing pod
	UpdatePod(ctx api.Context, pod *api.Pod) error
	// Delete an existing pod
	DeletePod(ctx api.Context, podID string) error
}

Registry is an interface implemented by things that know how to store Pod objects.

func NewRegistry

func NewRegistry(s Storage) Registry

NewRegistry returns a new Registry interface for the given Storage. Any mismatched types will panic.

type ResourceGetter

type ResourceGetter interface {
	Get(api.Context, string) (runtime.Object, error)
}

ResourceGetter is an interface for retrieving resources by ResourceLocation.

type Storage

type Storage interface {
	apiserver.RESTDeleter
	apiserver.RESTLister
	apiserver.RESTGetter
	apiserver.ResourceWatcher

	Create(ctx api.Context, obj runtime.Object) (runtime.Object, error)
	Update(ctx api.Context, obj runtime.Object) (runtime.Object, bool, error)
}

Storage is an interface for a standard REST Storage backend TODO: move me somewhere common
