Chapter 6 Lab - docker-machine create fails with error
Hello,
I'm working on Chapter 6, Exercise 3 where we create a host "demo" using docker-machine. I issue the actual docker-machine create command and everything appears to go smoothly until it tries to create the machine and then I get the following output:
Error creating machine: Error running provisioning: ssh command error:
command : sudo systemctl -f start docker
err : exit status 1
output : Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
The command I used was the following (added a flag so I could use my own SSH key):
docker-machine create --driver digitalocean --digitalocean-access-token=$DO_TOKEN --digitalocean-ssh-key-fingerprint $DIGITALOCEAN_SSH_KEY_FINGERPRINT demo
Pasting the entirety of the screen logs here below. Thanks in advance for any help or pointers!

Hi Lee,
I could re-produce the issue with Docker Machine, which currently ships with "Docker for Mac". This seems to fixed with Docker Machine's 0.12.0 release. Please update it manually for now from, as given in the release page.
