Using the platform independent daemon-configuration-file seems much cleaner.

Add "hosts" to your /etc/docker/daemon.json (or /custom/path/to/daemon/config.json if you're using --config-file option while starting the dockerd):

{
...
"hosts": ["tcp://127.0.0.1:2375", "unix:///var/run/docker.sock"],
...
}

restart the daemon:

sudo systemctl restart docker
