Types ¶
type Driver ¶
type Driver struct { ManagerIp string ManagerPort string MonitorIp string MonitorPort string // contains filtered or unexported fields }
func (*Driver) ApplyDiff ¶
ApplyDiff applies the new layer into a root docker pull will call this func TODO: this func has bug
func (*Driver) Capabilities ¶
func (d *Driver) Capabilities() graphdriver.Capabilities
func (*Driver) Changes ¶
func (d *Driver) Changes(id, parent string) ([]graphPlugin.Change, error)
Changes produces a list of changes between the specified layer and its parent layer. If parent is "", then all changes will be ADD changes
func (*Driver) Cleanup ¶
Cleanup any state created by overlay which should be cleaned when daemon is being shutdown. For now, we just have to unmount the bind mounted we had created
func (*Driver) CreateReadWrite ¶
func (d *Driver) CreateReadWrite(id, parent, mountlabel string, storageOpt map[string]string) (retErr error)
为容器层创建目录
func (*Driver) Diff ¶
func (d *Driver) Diff(id, parent string) io.ReadCloser
Diff produces an archive of the changes between the specified layer and its parent layer which may be ""
func (*Driver) DiffSize ¶
DiffSize calculates the changes between the specified id and its parent and returns the size in bytes of the changes relative to its base filesystem directory
func (*Driver) Get ¶
func (d *Driver) Get(id, mountLabel string) (containerfs.ContainerFS, error)
Get creates and mounts the required file system for the given id and returns the mount path
func (*Driver) GetMetadata ¶
GetMetadata returns metadata about the overlay driver such as the LowerDir, UpperDir, WorkDir, and MergeDir used to store data
func (*Driver) Put ¶
Put unmounts the mount path created for the give id. It also removes the 'merged' directory to force the kernel to unmount the overlay mount in other namespaces.
