Constants 

const (

	// AffinityTimeout is the maximum time that CheckAffinity is allowed to take; this
	// needs to be more than long enough for AffinityConfirmCount HTTP requests to
	// complete in a busy CI cluster, but shouldn't be too long since we will end up
	// waiting the entire time in the tests where affinity is not expected.
	AffinityTimeout = 2 * time.Minute

	// AffinityConfirmCount is the number of needed continuous requests to confirm that
	// affinity is enabled.
	AffinityConfirmCount = 15
)
const (

	// RespondingTimeout is how long to wait for a service to be responding.
	RespondingTimeout = 2 * time.Minute
)

func CheckSCTPModuleLoadedOnNodes 

func CheckSCTPModuleLoadedOnNodes(f *framework.Framework, nodes *v1.NodeList) bool

CheckSCTPModuleLoadedOnNodes checks whether any node on the list has the sctp.ko module loaded For security reasons, and also to allow clusters to use userspace SCTP implementations, we require that just creating an SCTP Pod/Service/NetworkPolicy must not do anything that would cause the sctp kernel module to be loaded.

func DescribeSvc 

func DescribeSvc(ns string)

DescribeSvc logs the output of kubectl describe svc for the given namespace

func GetHTTPContent 

func GetHTTPContent(host string, port int, timeout time.Duration, url string) bytes.Buffer

GetHTTPContent returns the content of the given url by HTTP.

func GetHTTPContentFromTestContainer 

func GetHTTPContentFromTestContainer(config *e2enetwork.NetworkingTestConfig, host string, port int, timeout time.Duration, dialCmd string) (string, error)

GetHTTPContentFromTestContainer returns the content of the given url by HTTP via a test container.

func SIGDescribe 

func SIGDescribe(text string, body func()) bool

SIGDescribe annotates the test with the SIG label.

func StartServeHostnameService 

func StartServeHostnameService(c clientset.Interface, svc *v1.Service, ns string, replicas int) ([]string, string, error)

StartServeHostnameService creates a replication controller that serves its hostname and a service on top of it.

func StopServeHostnameService 

func StopServeHostnameService(clientset clientset.Interface, ns, name string) error

StopServeHostnameService stops the given service.

func TestHTTPHealthCheckNodePort 

func TestHTTPHealthCheckNodePort(host string, port int, request string, timeout time.Duration, expectSucceed bool, threshold int) error

TestHTTPHealthCheckNodePort tests a HTTP connection by the given request to the given host and port.

}

IPerfResults is a struct that stores some IPerfResult

func (*IPerfResults) Add 

func (i *IPerfResults) Add(ipr *IPerfResult)

Add adds a new result to the Results struct.

func (*IPerfResults) ToTSV 

func (i *IPerfResults) ToTSV() string

ToTSV exports an easily readable tab delimited format of all IPerfResults.

type StrSlice 

type StrSlice []string

StrSlice represents a string slice

type TestFixture 

type TestFixture struct {
	ServiceName string
	Namespace   string
	Client      clientset.Interface

	TestID string
	Labels map[string]string

	Name  string
	Image string
	// contains filtered or unexported fields
}

TestFixture is a simple helper class to avoid too much boilerplate in tests

func NewServerTest 

func NewServerTest(client clientset.Interface, namespace string, serviceName string) *TestFixture

NewServerTest creates a new TestFixture for the tests.

func (*TestFixture) BuildServiceSpec 

func (t *TestFixture) BuildServiceSpec() *v1.Service

BuildServiceSpec builds default config for a service (which can then be changed)

func (*TestFixture) Cleanup 

func (t *TestFixture) Cleanup() []error

Cleanup cleans all ReplicationControllers and Services which this object holds.

func (*TestFixture) CreateRC 

func (t *TestFixture) CreateRC(rc *v1.ReplicationController) (*v1.ReplicationController, error)

CreateRC creates a replication controller and records it for cleanup.

func (*TestFixture) CreateService 

func (t *TestFixture) CreateService(service *v1.Service) (*v1.Service, error)

CreateService creates a service, and record it for cleanup

func (*TestFixture) DeleteService 

func (t *TestFixture) DeleteService(serviceName string) error

DeleteService deletes a service, and remove it from the cleanup list

type UDPPokeParams 

type UDPPokeParams struct {
	Timeout  time.Duration
	Response string
}

UDPPokeParams is a struct for UDP poke parameters.

type UDPPokeResult 

type UDPPokeResult struct {
	Status   UDPPokeStatus

	Response []byte // if code != 0
}

UDPPokeResult is a struct for UDP poke result.

type UDPPokeStatus 

type UDPPokeStatus string

UDPPokeStatus is string for representing UDP poke status. 

const (
	// UDPSuccess is UDP poke status which is success.
	UDPSuccess UDPPokeStatus = "Success"
	// UDPError is UDP poke status which is error.
	UDPError UDPPokeStatus = "UnknownError"
	// UDPTimeout is UDP poke status which is timeout.
	UDPTimeout UDPPokeStatus = "TimedOut"
	// UDPRefused is UDP poke status which is connection refused.
	UDPRefused UDPPokeStatus = "ConnectionRefused"
	// UDPBadResponse is UDP poke status which is bad response.
	UDPBadResponse UDPPokeStatus = "BadResponse"
)
