A quick example of creating a docker machine from your local terminal into a digital ocean droplet.
#Create a new droplet, install Docker, set the machine to active, set up the shell on the newly created machine.
docker-machine create --driver digitalocean --digitalocean-image ubuntu-16-04-x64 --digitalocean-access-token [ACCESS TOKEN HERE] [container-name] && docker-machine env [container-name] && eval $(docker-machine env [container-name])
#nginx
docker run -d -p 8000:80 --name webserver1 kitematic/hello-world-nginx
docker run -d -p 8001:80 --name webserver2 kitematic/hello-world-nginx
