We are going to be overriding a few of the default variables. To do this, update the group_vars/common.yml file to read like this, making sure you update the do_token value to reflect your own:

do_token: !vault |
          $ANSIBLE_VAULT;1.1;AES256

droplet:
  name: "WordPress"
  region: "lon1"
  size: "s-1vcpu-2gb"
  image: "centos-7-x64"
  timeout: "500"

wordpress:
  domain: "http://{{ hostvars['localhost'].droplet_ip }}/"
  title: "WordPress installed by Ansible on {{ os_family }} host in DigitalOcean"
  username: "ansible"
  password: "AnsiblePasswordForDigitalOcean"
  email: "[email protected]"
  theme: "sydney"
  plugins:
    - "jetpack"
    - "wp-super-cache"
    - "wordpress-seo"
    - "wordfence"
    - "nginx-helper"

As you can see, the majority of the values are their default values; the four values we are changing are:

• droplet.name: This is a simple update to the name so we can easily spot our instance in the DigitalOcean control panel.
• wordpress.domain: This is the important change here. As you can see, we are using the droplet_ip variable we set on our Ansible controller. To make the variable available to our WordPress host, we are telling Ansible to use the variable from localhost. If we hadn't done this, then the variable would not have been set; we will look at why in the next section.
• wordpress.title: A slight tweak to the title our WordPress site is configured to reflect where it is hosted.
• wordpress.password: Changing the password so it is more complex, as we are launching on a publicly available IP address.
