Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock:


Bash: 
    1.Create the docker group if it does not exist

$ sudo groupadd docker

    2.Add your user to the docker group.

$ sudo usermod -aG docker $USER

    3.Run the following command or Logout and login again and run (that doesnt work you may need to reboot your machine first)

$ newgrp docker

    4.Check if docker can be run without root

$ docker ps
thanks mkb
