Functions

func MakeEtcdItemKey

func MakeEtcdItemKey(ctx api.Context, prefix string, id string) (string, error)

MakeEtcdItemKey constructs etcd paths to a resource relative to prefix enforcing namespace rules. If no namespace is on context, it errors.

func MakeEtcdListKey

func MakeEtcdListKey(ctx api.Context, prefix string) string

MakeEtcdListKey constructs etcd paths to resource directories enforcing namespace rules

Types

type Registry

type Registry struct {
	tools.EtcdHelper
	// contains filtered or unexported fields
}

Registry implements BindingRegistry, ControllerRegistry, EndpointRegistry, MinionRegistry, PodRegistry and ServiceRegistry, backed by etcd.

func NewRegistry

func NewRegistry(helper tools.EtcdHelper, pods pod.Registry, endpoints endpoint.Registry) *Registry

NewRegistry creates an etcd registry.

func (*Registry) CreateController

func (r *Registry) CreateController(ctx api.Context, controller *api.ReplicationController) (*api.ReplicationController, error)

CreateController creates a new ReplicationController.

func (*Registry) CreateService

func (r *Registry) CreateService(ctx api.Context, svc *api.Service) (*api.Service, error)

CreateService creates a new Service.

func (*Registry) DeleteController

func (r *Registry) DeleteController(ctx api.Context, controllerID string) error

DeleteController deletes a ReplicationController specified by its ID.

func (*Registry) DeleteService

func (r *Registry) DeleteService(ctx api.Context, name string) error

DeleteService deletes a Service specified by its name.

func (*Registry) GetController

func (r *Registry) GetController(ctx api.Context, controllerID string) (*api.ReplicationController, error)

GetController gets a specific ReplicationController specified by its ID.

func (*Registry) GetService

func (r *Registry) GetService(ctx api.Context, name string) (*api.Service, error)

GetService obtains a Service specified by its name.

ListControllers obtains a list of ReplicationControllers.

func (*Registry) ListServices

func (r *Registry) ListServices(ctx api.Context) (*api.ServiceList, error)

ListServices obtains a list of Services.

func (*Registry) UpdateController

func (r *Registry) UpdateController(ctx api.Context, controller *api.ReplicationController) (*api.ReplicationController, error)

UpdateController replaces an existing ReplicationController.

func (*Registry) UpdateService

func (r *Registry) UpdateService(ctx api.Context, svc *api.Service) (*api.Service, error)

UpdateService replaces an existing Service.

func (*Registry) WatchControllers

func (r *Registry) WatchControllers(ctx api.Context, label labels.Selector, field fields.Selector, resourceVersion string) (watch.Interface, error)
