• Provisioning with Digital Ocean. Modify the Vagrantfile in /vagrant folder if necessary.

  config.vm.provider :digital_ocean do |provider, override|
    override.ssh.private_key_path = './do-office'
    override.vm.box = 'digital_ocean'
    override.vm.box_url = 'https://github.com/smdahlen/vagrant-digitalocean/raw/master/box/digital_ocean.box'
    override.puppet_install.puppet_version = "3.7.2"
    provider.token= ENV['DIGITALOCEAN_TOK']
    # Configurable parameters depending which droplet you want to create

    provider.region = "nyc1"
    provider.size = "1gb"
  end

$ vagrant up

$ cd opt
$ ./run mitsim.config
