示例1: Mount

// (is it not set coming in? why is it unset?)
func (daemon *Daemon) Mount(container *container.Container) error {
var layerID layer.ChainID
if container.ImageID != "" {
img, err := daemon.imageStore.Get(container.ImageID)
if err != nil {

}

}
rwlayer, err := daemon.layerStore.Mount(container.ID, layerID, container.GetMountLabel(), daemon.setupInitLayer)
if err != nil {
return err
}

}
logrus.Debugf("container mounted via layerStore: %v", dir)
if container.BaseFS != dir {
// The mount path reported by the graph driver should always be trusted on Windows, since the
// volume path for a given mounted layer may change over time. This should only be an error
// on non-Windows operating systems.
