Functions

func CreateEphemeralImages

func CreateEphemeralImages(
	vmi *v1.VirtualMachineInstance,
	diskCreator ephemeraldisk.EphemeralDiskCreatorInterface,
	disksInfo map[string]*DiskInfo,
) error

func ExtractImageIDsFromSourcePod

func ExtractImageIDsFromSourcePod(vmi *v1.VirtualMachineInstance, sourcePod *kubev1.Pod) (imageIDs map[string]string)

ExtractImageIDsFromSourcePod takes the VMI and its source pod to determine the exact image used by containerdisks and boot container images, which is recorded in the status section of a started pod; if the status section does not contain this info the tag is used. It returns a map where the key is the vlume name and the value is the imageID

func GenerateContainers

func GenerateContainers(vmi *v1.VirtualMachineInstance, config *virtconfig.ClusterConfig, imageIDs map[string]string, podVolumeName string, binVolumeName string) []kubev1.Container

func GenerateInitContainers

func GenerateInitContainers(vmi *v1.VirtualMachineInstance, config *virtconfig.ClusterConfig, imageIDs map[string]string, podVolumeName string, binVolumeName string) []kubev1.Container

func GenerateKernelBootContainer

func GenerateKernelBootContainer(vmi *v1.VirtualMachineInstance, config *virtconfig.ClusterConfig, imageIDs map[string]string, podVolumeName string, binVolumeName string) *kubev1.Container

func GenerateKernelBootInitContainer

func GenerateKernelBootInitContainer(vmi *v1.VirtualMachineInstance, config *virtconfig.ClusterConfig, imageIDs map[string]string, podVolumeName string, binVolumeName string) *kubev1.Container

func GetDiskTargetDirFromHostView

func GetDiskTargetDirFromHostView(vmi *v1.VirtualMachineInstance) (*safepath.Path, error)

func GetDiskTargetName

func GetDiskTargetName(volumeIndex int) string

func GetDiskTargetPartFromLauncherView

func GetDiskTargetPartFromLauncherView(volumeIndex int) (string, error)

GetDiskTargetPartFromLauncherView returns (path to disk image, image type, and error)

func GetDiskTargetPathFromLauncherView

func GetDiskTargetPathFromLauncherView(volumeIndex int) string

func GetImage

func GetImage(root *safepath.Path, imagePath string) (*safepath.Path, error)

func GetKernelBootArtifactPathFromLauncherView

func GetKernelBootArtifactPathFromLauncherView(artifact string) string

func GetLegacyVolumeMountDirOnHost

func GetLegacyVolumeMountDirOnHost(vmi *v1.VirtualMachineInstance) string

func GetVolumeMountDirOnGuest

func GetVolumeMountDirOnGuest(vmi *v1.VirtualMachineInstance) string

func GetVolumeMountDirOnHost

func GetVolumeMountDirOnHost(vmi *v1.VirtualMachineInstance) (*safepath.Path, error)

func SetKubeletPodsDirectory

func SetKubeletPodsDirectory(dir string)

func SetLocalDirectory

func SetLocalDirectory(dir string) error

func SetLocalDirectoryOnly

func SetLocalDirectoryOnly(dir string)

SetLocalDirectoryOnly TODO: Refactor this package. This package is used by virt-controller to set proper paths on the virt-launcher template and by virt-launcher to create directories at the right location. The functions have side-effects and mix path setting and creation which makes it hard to differentiate the usage per component.

func VerifyImage

func VerifyImage(diskInfo *DiskInfo) error

func VerifyQCOW2

func VerifyQCOW2(diskInfo *DiskInfo) error

Types

type DiskInfo

type DiskInfo struct {

NewKernelBootSocketPathGetter get the socket pat of the kernel-boot containerDisk. For testing a baseDir can be provided which can for instance point to /tmp.

type SocketPathGetter
