Functions

func AppImagePath

func AppImagePath(root string, imageID types.Hash) string

AppImagePath returns the path where an app image (i.e. unpacked ACI) is rooted (i.e. where its contents are extracted during stage0), based on the app image ID.

func AppImagesPath

func AppImagesPath(root string) string

AppImagesPath returns the path where the app images live

func AppRootfsPath

func AppRootfsPath(root string, imageID types.Hash) string

AppRootfsPath returns the path to an app's rootfs. imageID should be the app image ID.

func GetRktLockFD

func GetRktLockFD() (int, error)

func ImageManifestPath

func ImageManifestPath(root string, imageID types.Hash) string

ImageManifestPath returns the path to the app's manifest file inside the expanded ACI. id should be the app image ID.

func MetadataServicePublicURL

func MetadataServicePublicURL(ip net.IP) string

MetadataServicePublicURL returns the public URL used to host the metadata service

func PodManifestPath

func PodManifestPath(root string) string

PodManifestPath returns the path in root to the Pod Manifest

func RelAppImagePath

func RelAppImagePath(imageID types.Hash) string

RelAppImagePath returns the path of an application image relative to the stage1 chroot

func RelAppRootfsPath

func RelAppRootfsPath(imageID types.Hash) string

RelAppImagePath returns the path of an application's rootfs relative to the stage1 chroot

func Stage1ImagePath

func Stage1ImagePath(root string) string

Stage1ImagePath returns the path where the stage1 app image (unpacked ACI) is rooted, (i.e. where its contents are extracted during stage0).

func Stage1ManifestPath

func Stage1ManifestPath(root string) string

Stage1ManifestPath returns the path to the stage1's manifest file inside the expanded ACI.

func Stage1RootfsPath

func Stage1RootfsPath(root string) string

Stage1RootfsPath returns the path to the stage1 rootfs

func SupportsOverlay

func SupportsOverlay() bool

SupportsOverlay returns whether the system supports overlay filesystem
