Types ¶
type Mounter ¶
type Mounter struct {
// contains filtered or unexported fields
}
Mounter implements mount.Interface Currently, all docker containers receive their own mount namespaces. Mounter works by executing nsenter to run commands in the host's mount namespace.
func NewMounter ¶
NewMounter creates a new mounter for kubelet that runs as a container.
func (*Mounter) DeviceOpened ¶
DeviceOpened checks if block device in use by calling Open with O_EXCL flag. Returns true if open returns errno EBUSY, and false if errno is nil. Returns an error if errno is any error other than EBUSY. Returns with error if pathname is not a device.
func (*Mounter) EvalHostSymlinks ¶
EvalHostSymlinks returns the path name after evaluating symlinks.
func (*Mounter) ExistsPath ¶
ExistsPath checks if pathname exists. Error is returned on any other error than "file not found".
func (*Mounter) GetDeviceNameFromMount ¶
GetDeviceNameFromMount given a mount point, find the volume id from checking /proc/mounts
func (*Mounter) GetFSGroup ¶
GetFSGroup returns FSGroup of pathname.
func (*Mounter) GetFileType ¶
GetFileType checks for file/directory/socket/block/character devices.
func (*Mounter) GetMountRefs ¶
GetMountRefs finds all mount references to the path, returns a list of paths. Path could be a mountpoint path, device or a normal directory (for bind mount).
func (*Mounter) GetSELinuxSupport ¶
GetSELinuxSupport tests if pathname is on a mount that supports SELinux.
func (*Mounter) IsLikelyNotMountPoint ¶
IsLikelyNotMountPoint determines whether a path is a mountpoint by calling findmnt in the host's root mount namespace.
func (*Mounter) IsMountPointMatch ¶
func (*Mounter) IsMountPointMatch(mp mount.MountPoint, dir string) bool
IsMountPointMatch tests if dir and mp are the same path
func (*Mounter) List ¶
func (*Mounter) List() ([]mount.MountPoint, error)
List returns a list of all mounted filesystems in the host's mount namespace.
func (*Mounter) MakeRShared ¶
MakeRShared checks if path is shared and bind-mounts it as rshared if needed.
func (*Mounter) Mount ¶
Mount runs mount(8) in the host's root mount namespace. Aside from this aspect, Mount has the same semantics as the mounter returned by mount.New()
func (*Mounter) PathIsDevice ¶
PathIsDevice uses FileInfo returned from os.Stat to check if path refers to a device.
