Is it possible build a file in local by using template module?

[qiu jiawei]

Now,the template module woule build the template file and send to the remote host.

Is it possible for not send to the remote host?

I just want to see the file in local machine.

Yep.   The basics are that you could do:

    - local_action: template src=src.j2 dest=/path/to/local/system

However, this is a bit of a trap, if you are iterating over 500 hosts in a group, this will run 500 times, and clobber the file 500 times, possibly from multiple processes at once.

So this is better:

- hosts: webservers

  tasks:

     - blah

     - blah

- hosts: localhost

  tasks:

    - template:

- hosts: webservers

  tasks:

    - more 

    - more

Etc.

Absolutely. I use this technique to help combat the deprecation of include + with_items. Something like:

```
- name: normalize apache_sites_list into variable file
  local_action: template dest={{ apache_sites_var_file }} src="apache_sites_normalized.j2"
 
- name: load normalized `apache_sites_normalized` from variable file
  include_vars: "{{ apache_sites_var_file }}"
 
- name: remove variable file
  local_action: file path={{ apache_sites_var_file }} state=absent
 ```

where apache_sites_var_file is defined as:

  apache_sites_var_file: /tmp/ansible.apache_sites.{{ inventory_hostname }}.yml

NOTE that it uses {{ inventory_hostname }} to help prevent issues with parallel execution.

May be an "anti pattern" in this establishment; but helped me write cleaner playbooks.

I'm not even sure I'd call it a pattern :)

Writing variables to a template should be totally unneccessary if you're just going to load it in that way, because of the way lazy-loading in Ansible already works.

If you want dog to contain the value of cat, you can just predeclare dog:

dog: "{{ cat }}"

You don't have to write a variable file to load it.
