Cannot connect to the Docker daemon. Is the docker daemon running on this host?
If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
 sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
[root@apptest ~]# 
[root@apptest ~]# service docker start
Redirecting to /bin/systemctl start docker.service
[root@apptest ~]# docker images

[root@apptest ~]#
