示例1: verifyVolumesInfo

// It reads the container configuration and creates valid mount points for the old volumes.
func (daemon *Daemon) verifyVolumesInfo(container *container.Container) error {
// Inspect old structures only when we're upgrading from old versions
// to versions >= 1.7 and the MountPoints has not been populated with volumes data.
type volumes struct {
Volumes map[string]string
VolumesRW map[string]bool
}
