Functions

func BuildContainerLogsDirectory

func BuildContainerLogsDirectory(podLogsDir, podNamespace, podName string, podUID types.UID, containerName string) string

BuildContainerLogsDirectory builds absolute log directory path for a container in pod.

func BuildPodLogsDirectory

func BuildPodLogsDirectory(podLogsDir, podNamespace, podName string, podUID types.UID) string

BuildPodLogsDirectory builds absolute log directory path for a pod sandbox.

func GetHugepageLimitsFromResources

func GetHugepageLimitsFromResources(resources v1.ResourceRequirements) []*runtimeapi.HugepageLimit

GetHugepageLimitsFromResources returns limits of each hugepages from resources.

func GetStableKey

func GetStableKey(pod *v1.Pod, container *v1.Container) string

GetStableKey generates a key (string) to uniquely identify a (pod, container) tuple. The key should include the content of the container, so that any change to the container generates a new key.

func IsInPlacePodVerticalScalingAllowed

func IsInPlacePodVerticalScalingAllowed(pod *v1.Pod) bool
