centos7 docker版本应用无法添加镜像

[lxyevil]

操作系统版本：CentOS Linux release 7.7.1908 (Core)
内核版本：Linux localhost.localdomain 3.10.0-123.el7.x86_64 #1 SMP Mon Jun 30 12:09:22 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
应用添加本地镜像时提示报错“服务器内部错误，请联系管理员”
跟踪docker日志，报错信息如下：

我的也是centos7的环境，一开始也出现了这样的问题，你可以按照我这样操作一下：
第一步：vi /etc/sysconfig/docker 编辑这个文件，找到下面这一段话，
OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false'
将这段话改成：OPTIONS='--selinux-enabled=false --log-driver=journald --signature-verification=false'

第二步：然后关闭centos7的防火墙，和SELinux
临时关闭防火墙：systemctl stop firewalld
防火墙开机不启动：systemctl disable firewalld
临时关闭SELinux：setenforce 0

第三步：重新启动docker环境，执行：
docker run -d -p 80:80 -v /var/run/docker.sock:/var/run/docker.sock -e VUL_IP=xxx.xxx.xxx.xxx vulfocus/vulfocus

第四步：打开靶场界面，登录靶场后进行添加镜像。

这个问题大佬已经帮我解决了，如果不改这些配置文件的话，可以加上--privileged参数，如：
docker run -d --privileged -p 80:80 -v /var/run/docker.sock:/var/run/docker.sock -e VUL_IP=XX.XX.XX.XX vulfocus/vulfocus，不过有容器逃逸的风险。

/var/run/docker.sock` 权限问题比较合适的方案为

1. 配置 Docker URL（vulfocus/settings.py），启用 tcp://127.0.0.1:2375
2. 添加 docker 用户组把 nginx 用户加进去
   nginx为运行用户

   groupadd docker
   usermod -aG docker nginx
   systemctl restart docker
