Functions

func ReserveMemory

func ReserveMemory(ctx context.Context, f *framework.Framework, id string, replicas, megabytes int, expectRunning bool, timeout time.Duration) func() error

ReserveMemory creates a replication controller with pods that, in summation, request the specified amount of memory.

func ReserveMemoryWithPriority

func ReserveMemoryWithPriority(ctx context.Context, f *framework.Framework, id string, replicas, megabytes int, expectRunning bool, timeout time.Duration, priorityClassName string) func() error

ReserveMemoryWithPriority creates a replication controller with pods with priority that, in summation, request the specified amount of memory.

func ReserveMemoryWithSelectorAndTolerations

func ReserveMemoryWithSelectorAndTolerations(ctx context.Context, f *framework.Framework, id string, replicas, megabytes int, expectRunning bool, timeout time.Duration, selector map[string]string, tolerations []v1.Toleration) func() error

ReserveMemoryWithSelectorAndTolerations creates a replication controller with pods with node selector that, in summation, request the specified amount of memory.

func SIGDescribe

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

SIGDescribe annotates the test with the SIG label.

func ScheduleAnySingleGpuPod

func ScheduleAnySingleGpuPod(ctx context.Context, f *framework.Framework, id string) error

ScheduleAnySingleGpuPod schedules a pod which requires single GPU of any type

func ScheduleGpuPod

func ScheduleGpuPod(ctx context.Context, f *framework.Framework, id string, gpuType string, gpuLimit int64) error

ScheduleGpuPod schedules a pod which requires a given number of gpus of given type

func WaitForClusterSizeFunc

func WaitForClusterSizeFunc(ctx context.Context, c clientset.Interface, sizeFunc func(int) bool, timeout time.Duration) error

WaitForClusterSizeFunc waits until the cluster size matches the given function.

func WaitForClusterSizeFuncWithUnready

func WaitForClusterSizeFuncWithUnready(ctx context.Context, c clientset.Interface, sizeFunc func(int) bool, timeout time.Duration, expectedUnready int) error

WaitForClusterSizeFuncWithUnready waits until the cluster size matches the given function and assumes some unready nodes.

Types

type CriticalAddonsOnlyError

type CriticalAddonsOnlyError struct{}

CriticalAddonsOnlyError implements the `error` interface, and signifies the presence of the `CriticalAddonsOnly` taint on the node.

func (CriticalAddonsOnlyError) Error

func (CriticalAddonsOnlyError) Error() string

type CustomMetricTestCase

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

CustomMetricTestCase is a struct for test cases.

func (*CustomMetricTestCase) Run

func (tc *CustomMetricTestCase) Run(ctx context.Context)

Run starts test case.

type DNSParamsLinear

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

DNSParamsLinear is a struct for number of DNS pods.

type HPAContainerResourceScaleTest

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

type HPAScaleTest

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

HPAScaleTest struct is used by the scale(...) function.
