I am dealing with nested loops inorder to build dynamic host using add\_host.

> Outer Loop: with\_items: “{{ command\_result.stdout\_lines }}” // gets me the list of users  
> Inner Loop: with\_items: “{{ dest\_ip.split(‘,’) }}” // gets me the list of IP addresses seperated by comma (,)

The below code works fine.

`

- name: Add hosts

include\_tasks: “{{ playbook\_dir }}/gethosts.yml”

vars:

dest\_ip: “{{ item.split(‘\t’)[0] }}”  
file\_dets: “{{ item.split(‘\t’)[1] }}”  
USER: “anystring”

# USER: “{% if item.split(‘\t’)[3] == ‘FrontEnd’ %}user1{% elif item.split(‘\t’)[3] == ‘BackEnd’ %}user2{% else %}{% endif %}”

ansible\_host: localhost  
install\_dir\_pass: “anystring”

# install\_dir: “{{ item.split(‘\t’)[2] }}”

with\_items: “{{ command\_result.stdout\_lines }}”  
`

Below is my include\_task gethost.yml file:
