Docker run centos - Problem

server@ubuntu:~$ docker run centos
Ran above command but got following error:-
Any idea how to resolve following error?

docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.40/containers/create: dial unix /var/run/docker.sock: connect: permission denied.
See ‘docker run --help’.

Because you are not accessing from root user. If wants to run from normal user then do entry in sudoers file.

Yes, Player you are right. It solved my problem.
