+## 全局设置
+
+在`docker`配置文件`/etc/docker/daemon.json`中设置
+
+```
+$ cat /etc/docker/daemon.json 
+{
+  "dns": ["119.29.29.29", "223.5.5.5", "223.6.6.6"]
+}
+```
+
+重新启动`docker`服务
+
+```
+$ sudo /etc/init.d/docker restart
+```
+
+## 容器设置
+
+使用属性`--dns`指定要载入容器的`DNS`
+
+```
+$ docker run -it --dns 233.5.5.5 --dns 233.6.6.6 ubuntu bash
+```
