可以在開另一台容器架好ip然後ping看看

可以看到2個容器可以互相ping到

如果想要再進去之前的容器內，可以執行:

```
docker start [ID] or [名稱]
docker attach [ID] or [名稱]
```

```
# docker start 2f7
# docker attach 2f7
# docker stop 2f7
```

如果想要在同一個容器內執行多個終端機時

```
# docker exec -it 2f7 /bin/bash
```

複製容器

```
#docker commit [ID] [新的容器名稱]:0.1
```

![](https://1005948644-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LZgzp55XQBZ7U2SrFtZ%2F-LaOwiaHzecR1RlXeJll%2F-LaP38sAYsduAsov5LVI%2Fimage.png?alt=media\&token=57bd5c26-8674-4963-a648-b4095bde7067)

```
# docker run -it --name=[新名稱] test:0.1 /bin/bash
```

![複製過的容器會保有原來容器內的東西](https://1005948644-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LZgzp55XQBZ7U2SrFtZ%2F-LaOwiaHzecR1RlXeJll%2F-LaP3Y2ahEmd-LlkMIDI%2Fimage.png?alt=media\&token=dd22a60c-4c8c-4d73-9125-5ff64d9593ed)

將容器上傳

刪除images檔，從docker hub上下載回來。

```
# docker rmi [docker hub 帳號]/test:0.1
```
