+If you want to use a remote docker host follow this instructions in the host:
+
+- Open the file `/lib/systemd/system/docker.service`, search for `ExecStart` and edit the value
+
+```text
+ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:${PORT} -H unix:///var/run/docker.sock
+```
+
+>The above command will bind the docker engine server to the Unix socket as well as TCP port of your choice. “0.0.0.0” means docker-engine accepts connections from all IP addresses.
+
+- Restart the daemon and Docker service
+
+```shell
+sudo systemctl daemon-reload
+sudo service docker restart
+```
+
+- Test if it is working
+
+```shell
+curl http://${IP}:${PORT}/version
