Variables ¶
var NodePrePullImageList = sets.NewString( imageutils.GetE2EImage(imageutils.Agnhost), "gcr.io/cadvisor/cadvisor:v0.47.2", busyboxImage, "registry.k8s.io/e2e-test-images/busybox@sha256:a9155b13325b2abef48e71de77bb8ac015412a566829f621d06bfae5c699b1b9", imageutils.GetE2EImage(imageutils.Nginx), imageutils.GetE2EImage(imageutils.Perl), imageutils.GetE2EImage(imageutils.Nonewprivs), imageutils.GetPauseImageName(), imageutils.GetE2EImage(imageutils.NodePerfNpbEp), imageutils.GetE2EImage(imageutils.NodePerfNpbIs), imageutils.GetE2EImage(imageutils.Etcd), )
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 ¶ added in v1.25.10
CountSampleDeviceAllocatable returns the number of devices of SampleDeviceResourceName advertised by a node allocatable
func CountSampleDeviceCapacity ¶ added in v1.25.10
CountSampleDeviceCapacity returns the number of devices of SampleDeviceResourceName advertised by a node capacity
func ExecCommand ¶ added in v1.28.0
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 ¶ added in v1.19.0
func IsCgroup2UnifiedMode() bool
IsCgroup2UnifiedMode returns whether we are running in cgroup v2 unified mode.
func PrePullAllImages ¶ added in v1.3.0
func PrePullAllImages() error
PrePullAllImages pre-fetches all images tests depend on so that we don't fail in an actual test.
func WaitForPodContainerRestartCount ¶ added in v1.28.0
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 ¶ added in v1.28.0
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 ¶ added in v1.28.0
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 ¶ added in v1.4.0
type ResourceCollector struct {
// contains filtered or unexported fields
}
ResourceCollector is a collector object which collects resource usage periodically from Cadvisor.
func NewResourceCollector ¶ added in v1.4.0
func NewResourceCollector(interval time.Duration) *ResourceCollector
NewResourceCollector creates a resource collector object which collects resource usage periodically from Cadvisor
func (*ResourceCollector) GetBasicCPUStats ¶ added in v1.4.0
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 ¶ added in v1.4.0
func (r *ResourceCollector) GetCPUSummary() e2ekubelet.ContainersCPUSummary
GetCPUSummary gets CPU usage in percentile.
func (*ResourceCollector) GetLatest ¶ added in v1.4.0
func (r *ResourceCollector) GetLatest() (e2ekubelet.ResourceUsagePerContainer, error)
GetLatest gets the latest resource usage from stats buffer.
func (*ResourceCollector) GetResourceTimeSeries ¶ added in v1.4.0
func (r *ResourceCollector) GetResourceTimeSeries() map[string]*perftype.ResourceSeries
GetResourceTimeSeries gets the time series of resource usage of each container.
func (*ResourceCollector) LogLatest ¶ added in v1.4.0
func (r *ResourceCollector) LogLatest()
LogLatest logs the latest resource usage.
func (*ResourceCollector) Reset ¶ added in v1.4.0
func (r *ResourceCollector) Reset()
Reset clears the stats buffer of resource collector.
func (*ResourceCollector) Start ¶ added in v1.4.0
func (r *ResourceCollector) Start()
Start starts resource collector and connects to the standalone Cadvisor pod then repeatedly runs collectStats.
func (*ResourceCollector) Stop ¶ added in v1.4.0
func (r *ResourceCollector) Stop()
Stop stops resource collector collecting stats. It does not clear the buffer
