func DropDisabledPodFields

func DropDisabledPodFields(pod, oldPod *api.Pod)

DropDisabledPodFields removes disabled fields from the pod metadata and spec. This should be called from PrepareForCreate/PrepareForUpdate for all resources containing a Pod

func DropDisabledTemplateFields

func DropDisabledTemplateFields(podTemplate, oldPodTemplate *api.PodTemplateSpec)

DropDisabledTemplateFields removes disabled fields from the pod template metadata and spec. This should be called from PrepareForCreate/PrepareForUpdate for all resources containing a PodTemplateSpec

func GetPodCondition

func GetPodCondition(status *api.PodStatus, conditionType api.PodConditionType) (int, *api.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 GetPodReadyCondition

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

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

func IsPodReady

func IsPodReady(pod *api.Pod) bool

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

func IsPodReadyConditionTrue

func IsPodReadyConditionTrue(status api.PodStatus) bool

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

func UpdatePodCondition

func UpdatePodCondition(status *api.PodStatus, condition *api.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 *api.PodSpec, mask ContainerType, 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.

With the default mask (zero value or DefaultContainers) VisitContainers will visit all containers enabled by current feature gates. If mask is non-zero, VisitContainers will unconditionally visit container types specified by mask, and no feature gate checks will be performed.

func VisitPodConfigmapNames

func VisitPodConfigmapNames(pod *api.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 *api.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.

type ContainerType

type ContainerType int

ContainerType signifies container type

const (
	// Containers is for normal containers
	Containers ContainerType = 1 << iota
	// InitContainers is for init containers
	InitContainers
	// EphemeralContainers is for ephemeral containers
	EphemeralContainers
)
const AllContainers ContainerType = (InitContainers | Containers | EphemeralContainers)

AllContainers specifies that all containers be visited

const DefaultContainers ContainerType = 0

DefaultContainers defines default behavior: Iterate containers based on feature gates

type ContainerVisitor

type ContainerVisitor func(container *api.Container, containerType ContainerType) (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
