Here is a user-data workaround that can be used to put in walters' suggested fix and then get the docker service up and running: 

#cloud-config
bootcmd:
  - sed s/After=cloud-final.service/After=cloud-init-local.service/ /usr/lib/systemd/system/docker-storage-setup.service > /etc/systemd/system/docker-storage-setup.service
  - systemctl daemon-reload
  - systemctl start --no-block docker.service
