Ansible loop - how to match up template values with with_items?

Question

I'm trying to create files that have values that match their with_items values.

I have a var list like so:

 sites:
   - domain: google.com
     cname: blue
   - domain: facebook.com
     cname: green
   - domain: twitter.com
     cname: red

I create individual files for each of the objects in the list in this task:

- name: Create files
  template:
    src: file.conf
    dest: "/etc/nginx/conf.d/{{item.cname}}.conf"
  with_items: "{{sites}}"

These both work great. What do I need to have in my template file for it create a file called blue.conf and has google.com in it only.

I have tried a lot of variations. The closest I got to was this:

   server {
        listen 80;
        listen [::]:80;
      {% for item in sites %}
        server_name  {{item.cname}}.es.nodesource.io;

        location / {
          proxy_pass {{item.domain}};
        }
      {% endfor %}
    }

That will create individual files, but every file has all the domains and cnames.

You already have the variable item defined and passed to the template, so there is no need to loop again.

Try:

server {
    listen 80;
    listen [::]:80;
    server_name  {{item.cname}}.es.nodesource.io;

    location / {
      proxy_pass {{item.domain}};
    }
}
