Types ¶
type ControllerLister ¶ added in v1.1.0
type ControllerLister interface {
// Lists all the replication controllers
List() ([]api.ReplicationController, error)
// Gets the services for the given pod
GetPodControllers(*api.Pod) ([]api.ReplicationController, error)
}
ControllerLister interface represents anything that can produce a list of ReplicationController; the list is consumed by a scheduler.
type EmptyControllerLister ¶ added in v1.1.0
type EmptyControllerLister struct{}
EmptyControllerLister implements ControllerLister on []api.ReplicationController returning empty data
func (EmptyControllerLister) GetPodControllers ¶ added in v1.1.0
func (f EmptyControllerLister) GetPodControllers(pod *api.Pod) (controllers []api.ReplicationController, err error)
GetPodControllers returns nil
type FakeControllerLister ¶ added in v1.1.0
type FakeControllerLister []api.ReplicationController
FakeControllerLister implements ControllerLister on []api.ReplicationController for test purposes.
func (FakeControllerLister) GetPodControllers ¶ added in v1.1.0
func (f FakeControllerLister) GetPodControllers(pod *api.Pod) (controllers []api.ReplicationController, err error)
GetPodControllers gets the ReplicationControllers that have the selector that match the labels on the given pod
type FakeNodeLister ¶ added in v1.1.0
type FakeNodeLister api.NodeList
FakeNodeLister implements NodeLister on a []string for test purposes.
type FakePodLister ¶
type FakePodLister []*api.Pod
FakePodLister implements PodLister on an []api.Pods for test purposes.
type FakeServiceLister ¶
type FakeServiceLister []api.Service
FakeServiceLister implements ServiceLister on []api.Service for test purposes.
func (FakeServiceLister) GetPodServices ¶
func (f FakeServiceLister) GetPodServices(pod *api.Pod) (services []api.Service, err error)
GetPodServices gets the services that have the selector that match the labels on the given pod
type FitPredicate ¶
type FitPredicate func(pod *api.Pod, existingPods []*api.Pod, node string) (bool, error)
FitPredicate is a function that indicates if a pod fits into an existing node.
type HostPriority ¶
type HostPriority struct {
Host string
Score int
}
HostPriority represents the priority of scheduling to a particular host, lower priority is better.
type HostPriorityList ¶
type HostPriorityList []HostPriority
type NodeLister ¶ added in v1.1.0
type NodeLister interface {
List() (list api.NodeList, err error)
}
NodeLister interface represents anything that can list nodes for a scheduler.
type PodLister ¶
type PodLister interface {
// TODO: make this exactly the same as client's Pods(ns).List() method, by returning a api.PodList
List(labels.Selector) ([]*api.Pod, error)
}
PodLister interface represents anything that can list pods for a scheduler.
type PriorityConfig ¶
type PriorityConfig struct {
Function PriorityFunction
Weight int
}
type PriorityFunction ¶
type PriorityFunction func(pod *api.Pod, podLister PodLister, nodeLister NodeLister) (HostPriorityList, error)
type ScheduleAlgorithm ¶
type ScheduleAlgorithm interface {
Schedule(*api.Pod, NodeLister) (selectedMachine string, err error)
}
Scheduler is an interface implemented by things that know how to schedule pods onto machines.
type ServiceLister ¶
type ServiceLister interface {
// Lists all the services
List() (api.ServiceList, error)
// Gets the services for the given pod
GetPodServices(*api.Pod) ([]api.Service, error)
}
ServiceLister interface represents anything that can produce a list of services; the list is consumed by a scheduler.
