## 課堂練習

### 容器使用

#### Docker Link 使用

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

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

![c1](/files/-MJV_XXBpMNjcXeO_y2L)

> #### 查詢 IP&#x20;

```
ifconfig
```

{% endtab %}

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

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

![c2](/files/-MJV__AZjAvO7amOrAvV)

> #### 查詢 IP&#x20;

```
ifconfig
```

> #### c2 直接 ping c1

```
ping c1
```

![c2](/files/-MJVaej9swDZtEr9zwmy)

{% hint style="info" %}
c2 能直接 ping c1，c1 則不行直接 ping c2
{% endhint %}

```
cat /etc/hosts
```

![](/files/-MJVdg_fJa2HKbaFUBUB)
{% endtab %}

{% tab title="vm1 - c3" %}

```
docker run -it --name c3 --network mynet busybox sh
```

```
