 # 2.1.3 Docker
+
+在配置 pwn 环境时，如果不想每次都用 socat，那么 [ctf_xinetd](https://github.com/Eadom/ctf_xinetd) 是个不错的选择。
+
+安装 docker：
+
+```shell
+$ sudo apt install docker.io
+```
+
+ctf_xinetd 用法示例：
+
+```shell
+$ git clone https://github.com/Eadom/ctf_xinetd.git
+$ sudo docker build -t "helloworld" ./ctf_xinetd/
+$ sudo docker run -d -p "0.0.0.0:10001:9999" -h "helloworld" --name="helloworld" helloworld
+```
+
+docker 的一些基本操作：
+
+```shell
+$ sudo docker images 
+REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
+helloworld          latest              80b466e06d24        2 hours ago         372 MB
