Functions ¶
func AppImageManifestPath ¶ added in v0.15.0
AppImageManifestPath returns the path to the app's ImageManifest file
func AppInfoPath ¶ added in v0.9.0
AppInfoPath returns the path to the app's appsinfo directory of a pod.
func AppRootfsPath ¶
AppRootfsPath returns the path to an app's rootfs.
func AppTreeStoreIDPath ¶ added in v0.9.0
AppTreeStoreIDPath returns the path to the app's treeStoreID file of a pod.
func AppsInfoPath ¶ added in v0.9.0
AppsInfoPath returns the path to the appsinfo directory of a pod.
func FSSupportsOverlay ¶ added in v1.7.0
FSSupportsOverlay checks whether the filesystem under which a specified path resides is compatible with OverlayFS
func GetRktLockFD ¶ added in v0.5.1
func ImageManifestPath ¶
ImageManifestPath returns the path to the app's manifest file of a pod.
func LookupGid ¶ added in v0.9.0
LookupGid reads the group file and returns the gid of the group specified by groupName.
func LookupPath ¶ added in v1.1.0
LookupPath search for bin in paths. If found, it returns its absolute path, if not, an error
func MetadataServicePublicURL ¶ added in v0.4.0
MetadataServicePublicURL returns the public URL used to host the metadata service
func PodManifestPath ¶ added in v0.5.1
PodManifestPath returns the path in root to the Pod Manifest
func RelAppPath ¶ added in v0.8.0
RelAppPath returns the path of an app relative to the stage1 chroot.
func RelAppRootfsPath ¶
RelAppRootfsPath returns the path of an app's rootfs relative to the stage1 chroot.
func SharedVolumesPath ¶ added in v0.9.0
SharedVolumesPath returns the path to the shared (empty) volumes of a pod.
func SliceToPath ¶ added in v0.6.1
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 ¶
Stage1ImagePath returns the path where the stage1 app image (unpacked ACI) is rooted, (i.e. where its contents are extracted during stage0).
func Stage1ManifestPath ¶
Stage1ManifestPath returns the path to the stage1's manifest file inside the expanded ACI.
func Stage1RootfsPath ¶
Stage1RootfsPath returns the path to the stage1 rootfs
func SupportsOverlay ¶ added in v0.5.2
func SupportsOverlay() bool
SupportsOverlay returns whether the system supports overlay filesystem
func SupportsUserNS ¶ added in v0.8.0
func SupportsUserNS() bool
SupportsUserNS returns whether the kernel has CONFIG_USER_NS set
func SystemdVersion ¶ added in v1.1.0
SystemdVersion parses and returns the version of a given systemd binary
Types ¶
type NetList ¶ added in v0.9.0
type NetList struct {
// contains filtered or unexported fields
}
NetList implements the flag.Value interface to allow specification of --net with and without values Example: --net="all,net1:k1=v1;k2=v2,net2:l1=w1"
func (*NetList) Contained ¶ added in v0.10.0
Check if the container needs to be put in a separate network namespace
func (*NetList) None ¶ added in v0.10.0
Check if 'none' (loopback only) networking has been requested
