NodePrePullImageList is a list of images used in node e2e test. These images will be prepulled before test running so that the image pulling won't fail in actual test.

var SIGDescribe = framework.SIGDescribe("node")

SIGDescribe annotates the test with the SIG label.

Functions

func CountSampleDeviceAllocatable

func CountSampleDeviceAllocatable(node *v1.Node) int64

CountSampleDeviceAllocatable returns the number of devices of SampleDeviceResourceName advertised by a node allocatable

func CountSampleDeviceCapacity

func CountSampleDeviceCapacity(node *v1.Node) int64

CountSampleDeviceCapacity returns the number of devices of SampleDeviceResourceName advertised by a node capacity

func ExecCommand

func ExecCommand(name string, c execCommand) []string

ExecCommand returns the command to execute in the container that implements execCommand and logs activities to a container specific log that persists across container restarts. The final log is written to container log so it can be retrieved by the test harness during the container execution. Log to /proc/1/fd/1 so that the lifecycle hook handler logs are captured as well.

func IsCgroup2UnifiedMode

func IsCgroup2UnifiedMode() bool

IsCgroup2UnifiedMode returns whether we are running in cgroup v2 unified mode.

func PrePullAllImages

func PrePullAllImages() error

PrePullAllImages pre-fetches all images tests depend on so that we don't fail in an actual test.

func WaitForPodContainerRestartCount

func WaitForPodContainerRestartCount(ctx context.Context, c clientset.Interface, namespace, podName string, containerIndex int, desiredRestartCount int32, timeout time.Duration) error

WaitForPodContainerRestartCount waits for the given Pod container to achieve at least a given restartCount TODO: eventually look at moving to test/e2e/framework/pod

func WaitForPodInitContainerRestartCount

func WaitForPodInitContainerRestartCount(ctx context.Context, c clientset.Interface, namespace, podName string, initContainerIndex int, desiredRestartCount int32, timeout time.Duration) error

WaitForPodInitContainerRestartCount waits for the given Pod init container to achieve at least a given restartCount TODO: eventually look at moving to test/e2e/framework/pod

func WaitForPodInitContainerToFail

func WaitForPodInitContainerToFail(ctx context.Context, c clientset.Interface, namespace, podName string, containerIndex int, reason string, timeout time.Duration) error

WaitForPodInitContainerToFail waits for the given Pod init container to fail with the given reason, specifically due to invalid container configuration. In this case, the container will remain in a waiting state with a specific reason set, which should match the given reason. TODO: eventually look at moving to test/e2e/framework/pod

Types

type ResourceCollector

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

ResourceCollector is a collector object which collects resource usage periodically from Cadvisor.

func NewResourceCollector

func NewResourceCollector(interval time.Duration) *ResourceCollector

NewResourceCollector creates a resource collector object which collects resource usage periodically from Cadvisor

func (*ResourceCollector) GetBasicCPUStats

func (r *ResourceCollector) GetBasicCPUStats(containerName string) map[float64]float64

GetBasicCPUStats returns the percentiles the cpu usage in cores for containerName. This method examines all data currently in the buffer.

func (*ResourceCollector) GetCPUSummary

func (r *ResourceCollector) GetCPUSummary() e2ekubelet.ContainersCPUSummary

GetCPUSummary gets CPU usage in percentile.

func (*ResourceCollector) GetLatest

func (r *ResourceCollector) GetLatest() (e2ekubelet.ResourceUsagePerContainer, error)

GetLatest gets the latest resource usage from stats buffer.

func (*ResourceCollector) GetResourceTimeSeries

func (r *ResourceCollector) GetResourceTimeSeries() map[string]*perftype.ResourceSeries

GetResourceTimeSeries gets the time series of resource usage of each container.

func (*ResourceCollector) LogLatest

func (r *ResourceCollector) LogLatest()

LogLatest logs the latest resource usage.

func (*ResourceCollector) Reset

func (r *ResourceCollector) Reset()

Reset clears the stats buffer of resource collector.

func (*ResourceCollector) Start

func (r *ResourceCollector) Start()

Start starts resource collector and connects to the standalone Cadvisor pod then repeatedly runs collectStats.

func (*ResourceCollector) Stop

func (r *ResourceCollector) Stop()

Stop stops resource collector collecting stats. It does not clear the buffer
