package mount

import "k8s.io/kubernetes/pkg/util/mount"

Package mount defines an interface to mounting filesystems.

TODO(thockin): This whole pkg is pretty linux-centric. As soon as we have an alternate platform, we will need to abstract further.

Functions ¶

func GetDeviceNameFromMount ¶

func GetDeviceNameFromMount(mounter Interface, mountPath string) (string, int, error)

GetDeviceNameFromMount: given a mnt point, find the device from /proc/mounts returns the device name, reference count, and error code

func GetMountRefs ¶

func GetMountRefs(mounter Interface, mountPath string) ([]string, error)

GetMountRefs finds all other references to the device referenced by mountPath; returns a list of paths.

Types ¶

type FakeAction ¶

type FakeAction struct {
	Action string // "mount" or "unmount"
	Target string // applies to both mount and unmount actions
	Source string // applies only to "mount" actions
	FSType string // applies only to "mount" actions
}

FakeAction objects are logged every time a fake mount or unmount is called.

type FakeMounter ¶

type FakeMounter struct {
	MountPoints []MountPoint
	Log         []FakeAction
}

FakeMounter implements mount.Interface for tests.

func (*FakeMounter) IsMountPoint ¶

func (f *FakeMounter) IsMountPoint(file string) (bool, error)

func (*FakeMounter) List ¶

func (f *FakeMounter) List() ([]MountPoint, error)

func (*FakeMounter) Mount ¶

func (f *FakeMounter) Mount(source string, target string, fstype string, flags uintptr, data string) error

func (*FakeMounter) ResetLog ¶

func (f *FakeMounter) ResetLog()

func (*FakeMounter) Unmount ¶

func (f *FakeMounter) Unmount(target string, flags int) error

type Interface ¶

type Interface interface {
	// Mount wraps syscall.Mount().
	Mount(source string, target string, fstype string, flags uintptr, data string) error
	// Umount wraps syscall.Mount().
	Unmount(target string, flags int) error
	// List returns a list of all mounted filesystems.  This can be large.
	// On some platforms, reading mounts is not guaranteed consistent (i.e.
	// it could change between chunked reads). This is guaranteed to be
	// consistent.
	List() ([]MountPoint, error)
	// IsMountPoint determines if a directory is a mountpoint.
	IsMountPoint(file string) (bool, error)
}

Each supported platform must define the following flags:

• FlagBind: specifies a bind mount
• FlagReadOnly: the mount will be read-only

func New ¶

func New() Interface

New returns a mount.Interface for the current system.

type MountPoint ¶

type MountPoint struct {
	Device string
	Path   string
	Type   string
	Opts   []string
	Freq   int
	Pass   int
}

This represents a single line in /proc/mounts or /etc/fstab.

type Mounter ¶

type Mounter struct{}

func (*Mounter) IsMountPoint ¶

func (mounter *Mounter) IsMountPoint(file string) (bool, error)

func (*Mounter) List ¶

func (mounter *Mounter) List() ([]MountPoint, error)

func (*Mounter) Mount ¶

func (mounter *Mounter) Mount(source string, target string, fstype string, flags uintptr, data string) error

func (*Mounter) Unmount ¶

func (mounter *Mounter) Unmount(target string, flags int) error
