Ansible jinja2 template with linux command

Question

I am learning ansible. i have written a jinja2 template for looping over a multiple values. However, i get those values from a linux command.

- name: fetching port ranges 
  command: ls /apache |grep redis|grep ".pid"  | awk -F"_" '{ print $2}'| awk -F"." '{print $1}'

Output of the above command will be :

Below is the jinja2 template

 [{% for range in port  %}
    "127.0.0.1:{{ range }}",
  {% endfor %}]

With "for loop" in the jinja2 template, i am trying iterate over the values generated by linux command but i am not sure how to save those values and use it in jinja2 template. Any help would be appreciated.

You need to register the result and then use the output from stdout_lines.

Try something like this:

- name: fetching port ranges 
  command: ls /apache |grep redis|grep ".pid"  | awk -F"_" '{ print $2}'| awk -F"." '{print $1}'
  register: result

- name: my template task
  template:
    src: <src>
    dest: <dest>
  vars:
    port: "{{ result.stdout_lines }}"
