在Centos7上运行docker时的权限

我在Centos7上安装Docker时遇到这个错误。我的搭档找到了解决办法

我的解决方案正在运行以下命令：

docker: Error response from daemon: 
  OCI runtime create failed: container_linux.go:349: 
    starting container process caused “process_linux.go:449: 
      container init caused \“write /proc/self/attr/keycreate: 
        permission denied\“”: unknown.
ERRO[0000] error waiting for container: context canceled

sudo setenforce Permissive
