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", It also returns if "name" exists.

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

GetPodReadyCondition 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

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

func UpdatePodCondition

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

UpdatePodCondition 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 VisitContainers

func VisitContainers(podSpec *v1.PodSpec, visitor ContainerVisitor) bool

VisitContainers invokes the visitor function with a pointer to the container spec of every container in the given pod spec. If visitor returns false, visiting is short-circuited. VisitContainers returns true if visiting completes, false if visiting was short-circuited.

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 ContainerVisitor

type ContainerVisitor func(container *v1.Container) (shouldContinue bool)

ContainerVisitor is called with each container spec, and returns true if visiting should continue.

type Visitor

type Visitor func(name string) (shouldContinue bool)

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