Functions

func CreateTestingNamespace added in v1.4.0

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

func DeleteTestingNamespace added in v1.4.0

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

func GetEtcdURLFromEnv added in v1.3.0

func GetEtcdURLFromEnv() string

func NewEtcdClient

func NewEtcdClient() etcd.Client

func NewIntegrationTestMasterConfig added in v1.2.0

func NewIntegrationTestMasterConfig() *master.Config

Returns the master config appropriate for most integration tests.

func NewMasterConfig added in v1.2.0

func NewMasterConfig() *master.Config

Returns a basic master config.

func NewSingleContentTypeSerializer added in v1.3.0

func NewSingleContentTypeSerializer(scheme *runtime.Scheme, serializer runtime.Serializer, contentType string) runtime.StorageSerializer

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

func RCFromManifest

func RCFromManifest(fileName string) *api.ReplicationController

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

func RequireEtcd

func RequireEtcd()

func RunAMaster

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

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, restClient *client.Client) (*api.ReplicationController, error)

ScaleRC scales the given rc to the given replicas.

func StartPods

func StartPods(namespace string, numPods int, host string, restClient *client.Client) error

StartPods check for numPods in namespace. If they exist, it no-ops, otherwise it starts up a temp rc, scales it to match numPods, then deletes the rc leaving behind the pods.

func StartRC

func StartRC(controller *api.ReplicationController, restClient *client.Client) (*api.ReplicationController, error)

StartRC creates given rc if it doesn't already exist, then updates it via kubectl's scaler.

func StopRC

func StopRC(rc *api.ReplicationController, restClient *client.Client) error

StopRC stops the rc via kubectl's stop library

func WithEtcdKey

func WithEtcdKey(f func(string))

Types

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 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
	RestClient *client.Client
	// Replication controller manager
	ControllerManager *replicationcontroller.ReplicationManager
	// 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 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.
