how to create many templates with an increasing variable (counter) in each?

Hi,

I need to create configuration files for php5-fpm and nginx for many domains. Each php5-fpm’s worker should run on separate port starting from 127.0.0.1:9001 and so on.

I started with the following configuration:

  • role: webserver

sites:

tasks:

  • name: create nginx-domain.conf
    template: src=nginx-domain.conf.j2 dest=/etc/nginx/conf.d/{{ item.1 }}.conf backup=yes
    with_subelements:

  • sites

  • site
    notify: Reload nginx

  • name: create php5-fpm-domain.conf
    template: src=php5-fpm-domain.conf.j2 dest=/etc/php5/fpm/pool.d/{{ item.1 }}.conf backup=yes
    with_subelements:

  • sites

  • site
    notify: Reload php

nginx-domain.conf.j2:

server {

listen 80;
server_name {{ item.1 }};
error_log /home/{{ item.0.name }}/logs/{{ item.1 }}.error.log error;
access_log /home/{{ item.0.name }}/logs/{{ item.1 }}.access.log combined buffer=16k flush=1m;

root /www/{{ item.0.name }}/domains/{{ item.1 }}/public_html/;
set $sock 127.0.0.1:{{ counter }}

include fastcgi_params;
fastcgi_index index.php;
fastcgi_intercept_errors on;
fastcgi_param DOCUMENT_ROOT /public_html;
fastcgi_param SCRIPT_FILENAME /public_html$fastcgi_script_name;

index index.html index.php;

location / {
try_files $uri $uri/ /index.php$is_args$args;
}

location ~* .php$ {
try_files $fastcgi_script_name =404;
fastcgi_pass $sock;
}

}

so, i need to increase {{ counter }} starting from 9001 in a template for every domain to use it in line ‘set $sock 127.0.0.1:{{ counter }}’, but i don’t know how to do that. i didn’t find anything useful via google/stackoverflow.
Maybe you can give me a hint or even some examples in which way to dig?
