Functions

func AppPath

func AppPath(root string, appName types.ACName) string

AppPath returns the path to an app's rootfs.

func AppRootfsPath

func AppRootfsPath(root string, appName types.ACName) string

AppRootfsPath returns the path to an app's rootfs.

func AppsPath

func AppsPath(root string) string

AppsPath returns the path where the apps within a pod live.

func GetRktLockFD

func GetRktLockFD() (int, error)

func ImageManifestPath

func ImageManifestPath(root string, appName types.ACName) string

ImageManifestPath returns the path to the app's manifest file inside a pod.

func MetadataServicePublicURL

func MetadataServicePublicURL(ip net.IP, token string) 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 RelAppPath

func RelAppPath(appName types.ACName) string

RelAppPath returns the path of an app relative to the stage1 chroot.

func RelAppRootfsPath

func RelAppRootfsPath(appName types.ACName) string

RelAppRootfsPath returns the path of an app's rootfs relative to the stage1 chroot.

func SliceToPath

func SliceToPath(unit string) (string, error)

SliceToPath explodes a slice name to its corresponding path in the cgroup hierarchy. For example, a slice named "foo-bar-baz.slice" corresponds to the path "foo.slice/foo-bar.slice/foo-bar-baz.slice". See systemd.slice(5)

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

func SupportsUserNS

func SupportsUserNS() bool

SupportsUserNS returns whether the kernel has CONFIG_USER_NS set
