### 容器使用

#### Docker Link 使用

{% tabs %}
{% tab title="vm1 - c1" %}

```
docker run -it --name c1 busybox sh
```

![c1](https://483685739-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MHFSfnhkNCUTnJ2hcGc%2F-MJVTR5uHb__9BRVi3y0%2F-MJV_XXBpMNjcXeO_y2L%2F00.jpg?alt=media\&token=75e8631e-14d5-4ca7-91eb-c5c166284aab)

> #### 查詢 IP&#x20;

```
ifconfig
```

{% endtab %}

{% tab title="vm1 - c2" %}

```
docker run -it --name c2 --link c1:c1 busybox sh
```

> #### 查詢 IP&#x20;

```
ifconfig
```

> #### c2 直接 ping c1

```
ping c1
```
