Provisioning with Vagrant and Ansible

This procedure uses Vagrant to provision a Digital Ocean (DO) droplet. If you prefere to use another cloud provider, edit Vagrantfile accordingly.

Install Vagrant along with Digital Ocean plugin.

On Fedora 27:
```
dnf install vagrant-digitalocean
```
Replace YOUR TOKEN with your DO token inside the Vagrantfile
Make sure to upload an SSH key to yuor DO account, then replace YOUR KEY NAME with you SSH key name inside the Vagrantfile
Modify deploy/ansible/group_vars/all.yml file by replacing all variables. Make sure to customize at least icaro.hostname. Set icaro.tls: "auto" if you want https certicate provisioned by Let's Encrypt.
Create the Icaro droplet:
```
vagrant up --provider=digital_ocean
```

You can destroy the droplet using:

vagrant destroy

The machine can be rebuilt using (all data will be lost):

vagrant rebuild
