• 区别：

1. save的对象是image，产生的文件需要用load来生成image；
2. export的对象是container，产生的文件需要用import来生成image。

  save        Save one or more images to a tar archive (streamed to STDOUT by default)
  load        Load an image from a tar archive or STDIN
  export      Export a container‘s filesystem as a tar archive
  import      Import the contents from a tarball to create a filesystem image
