Functions

func HostDevpath

func HostDevpath(s string, namespace string) (string, error)

HostDevpath returns host device path for a volume translation rules: INPUT VOL OUPUT COMMENT /path /dev/sda1 loop dev /dev/sda1 /dev/sda1 host full path myvol myvol /dev/sda1 vol dev path in host

func HostDevpaths

func HostDevpaths(l []string, namespace string) ([]string, error)

HostDevpaths applies the HostDevpath function to each path of the input list

func HostPath

func HostPath(s string, namespace string) (string, error)

HostPath expand a volume-relative path to a host full path.

Example:

INPUT VOL OUPUT COMMENT /path /path host full path myvol/path myvol /srv/myvol/path vol head relative path

func HostPathAndVol

func HostPathAndVol(s string, namespace string) (hostPath string, vol object.Vol, err error)

HostPathAndVol expand a volume-relative path to a host full path. It returns the host full path and the associated object volume if defined.

Example:

INPUT VOL host path COMMENT /path nil /path host full path myvol/path myvol /srv/myvol/path vol head relative path

func HostPaths

func HostPaths(l []string, namespace string) ([]string, error)

HostPaths applies the HostPath function to each path of the input list
