Types

type APIUtil

type APIUtil interface {
	// Create PersistentVolume object
	CreatePV(pv *v1.PersistentVolume) (*v1.PersistentVolume, error)

	// Delete PersistentVolume object
	DeletePV(pvName string) error
}

APIUtil is an interface for the K8s API

func NewAPIUtil

func NewAPIUtil(client *kubernetes.Clientset) APIUtil

NewAPIUtil creates a new APIUtil object that represents the K8s API

type FakeAPIUtil

type FakeAPIUtil struct {
	// contains filtered or unexported fields
}

FakeAPIUtil is a fake API wrapper for unit testing

func NewFakeAPIUtil

func NewFakeAPIUtil(shouldFail bool, cache *cache.VolumeCache) *FakeAPIUtil

NewFakeAPIUtil returns an APIUtil object that can be used for unit testing

func (*FakeAPIUtil) CreatePV

func (u *FakeAPIUtil) CreatePV(pv *v1.PersistentVolume) (*v1.PersistentVolume, error)

CreatePV will add the PV to the created list and cache

func (*FakeAPIUtil) DeletePV

func (u *FakeAPIUtil) DeletePV(pvName string) error

DeletePV will delete the PV from the created list and cache, and also add it to the deleted list
