```
**範例2：`docker pull <image>` or `docker image pull <image>`**
將雲端主機上的映像檔下載回本機
```
(joshhuAI)joshhu:~/ $ docker image ls [15:02:04]

```
其它範例：
```
docker pull joshhu/test-php-site:latest
```
**範例3：`docker image history <image>`**
列出一個映像檔的創建歷史，從新到舊，沒有`Dockerfile`時很好用
```

(joshhuAI)joshhu:~/ $
```
**範例4：`docker image save -o <tar file> <image>`**
將映像檔存入本機的`tar`檔案，不想用公開映像檔又沒自己的registry時很好用，可以用來轉移，備份等，通常配合`load`使用。
```
(joshhuAI)joshhu:~/ $ docker image save -o busybox.tar busybox:latest [15:13:06]
