Functions ¶

func CreateListener ¶

func CreateListener(endpoint string) (net.Listener, error)

CreateListener creates a listener on the specified endpoint.

func FromApiserverCache ¶

func FromApiserverCache(opts *metav1.GetOptions)

FromApiserverCache modifies <opts> so that the GET request will be served from apiserver cache instead of from etcd.

func GetAddressAndDialer ¶

func GetAddressAndDialer(endpoint string) (string, func(ctx context.Context, addr string) (net.Conn, error), error)

GetAddressAndDialer returns the address parsed from the given endpoint and a context dialer.

func GetBootTime ¶

func GetBootTime() (time.Time, error)

GetBootTime returns the time at which the machine was started, truncated to the nearest second

func GetNodenameForKernel ¶

func GetNodenameForKernel(hostname string, hostDomainName string, setHostnameAsFQDN *bool) (string, error)

GetNodenameForKernel gets hostname value to set in the hostname field (the nodename field of struct utsname) of the pod.

func IsUnixDomainSocket ¶

func IsUnixDomainSocket(filePath string) (bool, error)

IsUnixDomainSocket returns whether a given file is a AF_UNIX socket file Note that due to the retry logic inside, it could take up to 4 seconds to determine whether or not the file path supplied is a Unix domain socket

func LocalEndpoint ¶

func LocalEndpoint(path, file string) (string, error)

LocalEndpoint empty implementation

func NormalizePath ¶

func NormalizePath(path string) string

NormalizePath converts FS paths returned by certain go frameworks (like fsnotify) to native Windows paths that can be passed to Windows specific code

func SetNodeOwnerFunc ¶

func SetNodeOwnerFunc(c clientset.Interface, nodeName string) func(lease *coordinationv1.Lease) error

SetNodeOwnerFunc helps construct a newLeasePostProcessFunc which sets a node OwnerReference to the given lease object

Types ¶

type PodStartupLatencyTracker ¶

type PodStartupLatencyTracker interface {
	ObservedPodOnWatch(pod *v1.Pod, when time.Time)
	RecordImageStartedPulling(podUID types.UID)
	RecordImageFinishedPulling(podUID types.UID)
	RecordStatusUpdated(pod *v1.Pod)
	DeletePodStartupState(podUID types.UID)
}

PodStartupLatencyTracker records key moments for startup latency calculation, e.g. image pulling or pod observed running on watch.

func NewPodStartupLatencyTracker ¶

func NewPodStartupLatencyTracker() PodStartupLatencyTracker

NewPodStartupLatencyTracker creates an instance of PodStartupLatencyTracker
