Sorry I don't know much about the word 'save-out', but here are some common translations of docker commands in Chinese: save: 保存 load: 加载 export: 导出 import: 导入 It seems that there is a big difference between 'save' and 'export' in Docker, it will be great if you make a detail explanation :P

## 保存和加载镜像
|
|
|
|
### 保存镜像
|
|
如果要保存镜像到本地文件，可以使用 `docker save` 命令。
|
|
```
|
|
$ sudo docker images
|
|
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
|
ubuntu 14.04 c4ff7513909d 5 weeks ago 225.4 MB
|
|
...
|
|
$sudo docker save -o ubuntu_14.04.tar ubuntu:14.04
|
|
```
|
|
|
|
### 加载镜像
|
|
可以使用 `docker load` 从导出的本地文件中再加载到本地镜像库，例如
|
|
```
|
|
$ sudo docker load --input ubuntu_14.04.tar
|
|
```
|
|
或
|
|
```
|
|
$ sudo docker load < ubuntu_14.04.tar
|
|
```
|
|
这将加载镜像以及其相关的元数据信息（包括标签等）。
