Go to “Preferences”, “Clouds”, add a new deployment by clicking on “+”. Click on “Import credentials from Docker Machine”, “Detect”, and see a successful connection. You may have to check the IP address of your Docker Machine. Find the IP address of your Docker Machine as docker-machine ip <machine-name> and specify the correct IP address here.
