- hosts: localhost

vars:
instances:
- id: 1234

tasks:

set_fact:
new_proxy: "{{ new_proxy|default([]) + [ { 'id': item.id } ] }}"
loop: "{{ instances }}"
when: item.type == 'proxy'
- name: set Fact for db
set_fact:
new_db: "{{ new_proxy|default([]) + [ {'id': item.id } ] }}"
loop: "{{ instances }}"
when: item.type == 'db'
- name: set Fact for web
set_fact:
new_web: "{{ new_proxy|default([]) + [ {'id': item.id } ] }}"
loop: "{{ instances }}"
when: item.type == 'web'
- name: Print facts
debug:

{'web': new_web}, {'proxy': new_proxy} ] }}"
- name: Print final fact
debug:
var: new_instances
