Ansible playbook to launch a digitalocean droplet and then configure it to run Minecraft based on instructions from https://www.digitalocean.com/community/articles/how-to-set-up-a-minecraft-server-on-linux Note that some things are hardwired: the name of the droplet, the version of minecraft

minecraft_do.yml

# http://www.ansibleworks.com/docs/modules.html#digital-ocean

# Create a new Droplet
# Will return the droplet details including the droplet id (used for idempotence)
