title: Ansible variable in jinja2 template
body: <p>I have a small playbook with jinja2 template to apply nginx configuration.
  This template uses some variables.</p>
  <p>In my variables file I have:</p>
  <pre><code>---
  domains:
    - test@example.com
  </code></pre>
  <p>In my template file I have:</p>
  <pre><code>server_name  {{ domains }};
  </code></pre>
  <p>Once playbook deployed, in my config file I have:</p>
  <pre><code>server_name  ['test@example.com'];
  </code></pre>
  <p>What can I do to print only test@example.com? without ['...']?</p>
  <p>Thanks in advance!</p>
