yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y
```



#### 启动$Docker$

```shell
systemctl start docker
```



#### 配置镜像源

```shell
mkdir -p /etc/docker

tee /etc/docker/daemon.json <<EOF
{
    "registry-mirrors": [
        "https://docker.m.daocloud.io",
        "https://huecker.io",
        "https://dockerhub.timeweb.cloud",
        "https://noohub.ru"
    ]
}
EOF

systemctl daemon-reload
systemctl restart docker
```



#### 检查是否安装成功

```shell
docker run hello-world
```

#### 卸载 docker

```shell
yum remove docker-ce
```

#### 删除镜像、容器、配置文件等内容

```



#### 下载$Ununtu$容器

```

```

#### 进入容器

```
docker run -it ubuntu /bin/bash
```

```
-i: 交互式操作。
-t: 终端。
ubuntu: ubuntu 镜像。
/bin/bash：放在镜像名后的是命令，这里我们希望有个交互式 Shell，因此用的是 /bin/bash。
```
