해결방안은 아래와 같다. (기본에 yum 을 이용하여 설치하다 보니 발생한 에러다.)
먼저 docker-selinux 가 설치되어 있는지 체크한다.
[binrang@binrang ~]$ yum list installed|grep docker

[binrang@binrang ~]$

yum remove를 이용하여 docker 관련 패키지를 제거한다.

4. Docker 버전의 'Hello World'를 구동하여 설치를 확인해 본다.
[root@binrang ~]# docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
