//If you want to run docker as non-root user then you need to add it to the docker group.
// 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 doesn't work you may need to reboot your machine first)
$ newgrp docker
