}


#abilitare TCP debian
modificare /lib/systemd/system/docker.service
modificare riga:
ExecStart=/usr/bin/dockerd -H fd://  oppure ExecStart=/usr/bin/dockerd -H unix:// 
  in
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://   oppure
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock 

systemctl daemon-reload

#verifica il funzionamento 
docker -H tcp://<REMOTE_IP>:2375 info
