更新软件源，漫长的时间……

1
osboxes@osboxes:~$ sudo apt update

更新完成之后安装docker和docker-compose

1
osboxes@osboxes:~$ sudo apt install docker.io docker-compose

使用下列命令查看版本判断是否安装成功

osboxes@osboxes:~$ docker-compose -v
docker-compose version 1.25.0, build unknown
osboxes@osboxes:~$ docker -v
Docker version 24.0.5, build 24.0.5-0ubuntu1~20.04.1

接下来到GZ:CTF根据文档部署，首先创建一个GZCTF文件夹，根据文档创建配置appsettings.json和docker-compose.yml文件

appsettings.json

osboxes@osboxes:~/GZCTF$ vi appsettings.json
