POAnsible: are variables for specific role and inventory possible?
text
Body
copied!<p>Let's say I have a nginx config file created from a template, which I use to configure certain hosts to redirect a server name from http to https:</p> <pre><code>server { listen 80; server_name {{ server_name }}; rewrite ^ https://$server_name$request_uri? permanent; } </code></pre> <p>Say I have two web sites hosted on the same machine:</p> <ul> <li>site A</li> <li>site B</li> </ul> <p>each has its own server name and each needs the redirection above. At the same time let's say I have at least two separate deployment configurations, each represented by its own inventory file and its group_vars/ folder, for example:</p> <ul> <li>vagrant onebox</li> <li>production</li> </ul> <p>each using a different server name. So now I have 2*2 = 4 separate server names:</p> <ul> <li>sitea.myonebox.com</li> <li>siteb.myonebox.com</li> <li>sitea.production.com</li> <li>siteb.production.com</li> </ul> <p>I can't figure out how to define all of those 4 variables. I can't define two separate variables under group_vars/ because the j2 template expects only one variable name {{server_name}}, so I'd have to define the same template twice to make that work.</p> <p>The other option is to have sitea and siteb as two separate roles (which I was going to do anyway), and store sever_name in roles/sitea/vars/main.yml, however that setup does not take inventory in consideration, meaning that I'd be down to 2 variables rather than 4.</p> <p>Is this possible at all without template duplication or is Ansible not supporting this kind of scenario just yet?</p>
