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 clientset.Interface) (*api.ReplicationController, error)

ScaleRC scales the given rc to the given replicas.

func StopRC(rc *api.ReplicationController, clientset clientset.Interface) 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 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
	// 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.
