Deploy site on Digital Ocean Ubuntu Droplet with Ansible

OK. Well I setup an empty Ubuntu 14.0.4 droplet at Digital Ocean. Did not add keys yet, but can do so later and understood that you do not need it right away to deploy with Ansible. Wanted to test if I can setup Bedrock on that server using the Ansible setup.
In site.com/wprmote.com/ansible/group_vars/ I configured the development and production files. Running vagrant locally after the the intial setup as followed at https://github.com/roots/bedrock-ansible went well:

vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'roots/bedrock' is up to date...
==> default: Resuming suspended VM...
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Warning: Connection refused. Retrying...
==> default: Machine booted and ready!
==> default: Checking for host entries

Then I tried

./deploy.sh production site.com

and hit a snag

Using -vvv is perhaps possible running ssh, but not this script.

Checking out https://github.com/roots/roots-example-project.com/blob/master/ansible/group_vars/production now. Seems I am missing stuff in my production file…
