# 安装 Docker

### 1、安装前配置

添加Docker PGP key:

因为国内对docker官网的网速支持并不友好，我将使用清华镜像作为代替，阿里云docker对一些镜像支持也太友好故未选择。

```
curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian/gpg | sudo apt-key add -
```

配置Docker APT repository：

 (Kali is based on Debian testing, which will be called buster upon release, and Docker now has support for it)

```
echo 'deb https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian/ buster stable' | sudo tee /etc/apt/sources.list.d/docker.list
```

更新APT

```
 
```

### **2、安装Docker**

如果您安装了旧版本的Docker，请卸载它们：

```
sudo apt-get remove docker docker-engine docker.io
```

安装docker：

```
sudo apt-get install docker-ce
```

查看docker状态：

```
sudo systemctl status docker
```

启动docker：

```
sudo systemctl start docker
```

开机自动启动：

```
sudo systemctl enable docker
```
