Make sure to create a firewall https://www.digitalocean.com/docs/networking/firewalls/how-to/create/ for the droplet. Open ports 22 (for SSH) and 2376 (for Docker).

SSH tunnel:

docker-machine ssh docker-sandbox -N -L 1433:localhost:1433 -L 6379:localhost:6379 -L 5672:localhost:5672 -L 15672:localhost:15672
