如果想在容器內看到ip位置

```
# yum install net-tools
```

可以在開另一台容器架好ip然後ping看看

![](/files/-LaOykpRSjhSrer7x4Pc)

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
```

![](/files/-LaP2j_Qd8ObrZPfbkoq)

複製容器

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

![](/files/-LaP38sAYsduAsov5LVI)

```
# 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](/files/-LaP3Y2ahEmd-LlkMIDI)

將容器上傳

![](/files/-LaP4KSQBvgwweNjz1hE)

![成功上傳docker hub](/files/-LaP4eqCk9NYw1j5-V71)

刪除images檔，從docker hub上下載回來。

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