Enable Docker Remote API

Navigate to /lib/systemd/system in your terminal and open docker.service file
```
  vi /lib/systemd/system/docker.service
```
Find the line which starts with ExecStart and adds -H=tcp://0.0.0.0:2375 to make it look like
```
  ExecStart=/usr/bin/dockerd -H=fd:// -H=tcp://0.0.0.0:2375
```
Save the Modified File
Reload the docker daemon
```
  systemctl daemon-reload
```
Restart the container
```
  sudo service docker restart
```
