Functions

func CreateTestingNamespace

func CreateTestingNamespace(baseName string, apiserver *httptest.Server, t *testing.T) *v1.Namespace

func DeleteTestingNamespace

func DeleteTestingNamespace(ns *v1.Namespace, apiserver *httptest.Server, t *testing.T)

func EtcdMain

func EtcdMain(tests func() int)

func FindFreeLocalPort

func FindFreeLocalPort() (int, error)

FindFreeLocalPort returns the number of an available port number on the loopback interface. Useful for determining the port to launch a server on. Error handling required - there is a non-zero chance that the returned port number will be bound by another process after this function returns.

func GetEtcdURL

func GetEtcdURL() string

return the EtcdURL

func GetPauseImageName

func GetPauseImageName(c clientset.Interface) string

GetPauseImageName fetches the pause image name for the same architecture as the apiserver.

func GetServerArchitecture

func GetServerArchitecture(c clientset.Interface) string

GetServerArchitecture fetches the architecture of the cluster's apiserver.

func NewIntegrationTestMasterConfig

func NewIntegrationTestMasterConfig() *master.Config

Returns the master config appropriate for most integration tests.

func NewIntegrationTestNodePreparer

func NewIntegrationTestNodePreparer(client clientset.Interface, countToStrategy []testutils.CountToStrategy, nodeNamePrefix string) testutils.TestNodePreparer

func NewMasterConfig

func NewMasterConfig() *master.Config

Returns a basic master config.

func NewSingleContentTypeSerializer

func NewSingleContentTypeSerializer(scheme *runtime.Scheme, info runtime.SerializerInfo) runtime.StorageSerializer

NewSingleContentTypeSerializer wraps a serializer in a NegotiatedSerializer that handles one content type

func RCFromManifest

func RCFromManifest(fileName string) *v1.ReplicationController

RCFromManifest reads a .json file and returns the rc in it.

func RunParallel

func RunParallel(task Task, numTasks, numWorkers int)

RunParallel spawns a goroutine per task in the given queue

func ScaleRC

func ScaleRC(name, ns string, replicas int32, clientset internalclientset.Interface) (*api.ReplicationController, error)

ScaleRC scales the given rc to the given replicas.

func StopRC

StopRC stops the rc via kubectl's stop library

Types

type CloseFunc

type CloseFunc func()

CloseFunc can be called to cleanup the master

func RunAMaster

func RunAMaster(masterConfig *master.Config) (*master.Master, *httptest.Server, CloseFunc)

func RunAMasterUsingServer

func RunAMasterUsingServer(masterConfig *master.Config, s *httptest.Server, masterReceiver MasterReceiver) (*master.Master, *httptest.Server, CloseFunc)

type Config

type Config struct {
	// If nil, a default is used, partially filled configs will not get populated.
	MasterConfig            *master.Config
	StartReplicationManager bool
	// Client throttling qps
	QPS float32
	// Client burst qps, also burst replicas allowed in rc manager
	Burst int
}

Config is a struct of configuration directives for NewMasterComponents.

type IntegrationTestNodePreparer

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

func (*IntegrationTestNodePreparer) CleanupNodes

func (p *IntegrationTestNodePreparer) CleanupNodes() error

func (*IntegrationTestNodePreparer) PrepareNodes

func (p *IntegrationTestNodePreparer) PrepareNodes() error

type MasterComponents

type MasterComponents struct {
	// Raw http server in front of the master
	ApiServer *httptest.Server
	// Kubernetes master, contains an embedded etcd storage
	KubeMaster *master.Master
	// Restclient used to talk to the kubernetes master
	ClientSet clientset.Interface
	// Replication controller manager
	ControllerManager *replicationcontroller.ReplicationManager
	// CloseFn shuts down the server
	CloseFn CloseFunc
	// contains filtered or unexported fields
}

MasterComponents is a control struct for all master components started via NewMasterComponents. TODO: Include all master components (scheduler, nodecontroller). TODO: Reconcile with integration.go, currently the master used there doesn't understand how to restart cleanly, which is required for each iteration of a benchmark. The integration tests also don't make it easy to isolate and turn off components at will.

func NewMasterComponents

func NewMasterComponents(c *Config) *MasterComponents

NewMasterComponents creates, initializes and starts master components based on the given config.

func (*MasterComponents) Stop

func (m *MasterComponents) Stop(apiServer, rcManager bool)

type MasterHolder

type MasterHolder struct {
	Initialized chan struct{}
	M           *master.Master
}

MasterHolder implements

func (*MasterHolder) SetMaster

func (h *MasterHolder) SetMaster(m *master.Master)

type MasterReceiver

type MasterReceiver interface {
	SetMaster(m *master.Master)
}

MasterReceiver can be used to provide the master to a custom incoming server function

type Task

type Task func(id int) error

Task is a function passed to worker goroutines by RunParallel. The function needs to implement its own thread safety.
