Functions

func FindPort

func FindPort(pod *v1.Pod, svcPort *v1.ServicePort) (int, error)

FindPort locates the container port for the given pod and portName. If the targetPort is a number, use that. If the targetPort is a string, look that string up in all named ports in all containers in the target pod. If no match is found, fail.

func GetContainerStatus

func GetContainerStatus(statuses []v1.ContainerStatus, name string) (v1.ContainerStatus, bool)

GetContainerStatus extracts the status of container "name" from "statuses". It also returns if "name" exists.

func GetExistingContainerStatus

func GetExistingContainerStatus(statuses []v1.ContainerStatus, name string) v1.ContainerStatus

GetExistingContainerStatus extracts the status of container "name" from "statuses", and returns empty status if "name" does not exist.

func GetPodCondition

func GetPodCondition(status *v1.PodStatus, conditionType v1.PodConditionType) (int, *v1.PodCondition)

GetPodCondition extracts the provided condition from the given status and returns that. Returns nil and -1 if the condition is not present, and the index of the located condition.

func GetPodConditionFromList

func GetPodConditionFromList(conditions []v1.PodCondition, conditionType v1.PodConditionType) (int, *v1.PodCondition)

GetPodConditionFromList extracts the provided condition from the given list of condition and returns the index of the condition and the condition. Returns -1 and nil if the condition is not present.

func GetPodReadyCondition

func GetPodReadyCondition(status v1.PodStatus) *v1.PodCondition

Extracts the pod ready condition from the given status and returns that. Returns nil if the condition is not present.

func IsPodAvailable

func IsPodAvailable(pod *v1.Pod, minReadySeconds int32, now metav1.Time) bool

IsPodAvailable returns true if a pod is available; false otherwise. Precondition for an available pod is that it must be ready. On top of that, there are two cases when a pod can be considered available: 1. minReadySeconds == 0, or 2. LastTransitionTime (is set) + minReadySeconds < current time

func IsPodReady

func IsPodReady(pod *v1.Pod) bool

IsPodReady returns true if a pod is ready; false otherwise.

func IsPodReadyConditionTrue

func IsPodReadyConditionTrue(status v1.PodStatus) bool

IsPodReady returns true if a pod is ready; false otherwise.

func UpdatePodCondition

func UpdatePodCondition(status *v1.PodStatus, condition *v1.PodCondition) bool

Updates existing pod condition or creates a new one. Sets LastTransitionTime to now if the status has changed. Returns true if pod condition has changed or has been added.

func VisitPodConfigmapNames

func VisitPodConfigmapNames(pod *v1.Pod, visitor Visitor) bool

VisitPodConfigmapNames invokes the visitor function with the name of every configmap referenced by the pod spec. If visitor returns false, visiting is short-circuited. Transitive references (e.g. pod -> pvc -> pv -> secret) are not visited. Returns true if visiting completed, false if visiting was short-circuited.

func VisitPodSecretNames

func VisitPodSecretNames(pod *v1.Pod, visitor Visitor) bool

VisitPodSecretNames invokes the visitor function with the name of every secret referenced by the pod spec. If visitor returns false, visiting is short-circuited. Transitive references (e.g. pod -> pvc -> pv -> secret) are not visited. Returns true if visiting completed, false if visiting was short-circuited.

Types

type Visitor

type Visitor func(name string) (shouldContinue bool)

Visitor is called with each object name, and returns true if visiting should continue
