Создайте ansible groupvars из group_vars как dict

Question

Что здесь не так?

hosts.yml

---
all:
  hosts:
    computenode[1:2]:
  children:
    computenodes:
      hosts:
        computenode[1:2]:
    net_192_168_99:
      children:
        computenodes:
    net_192_168_123:
      children:
        computenodes:

group_vars / net_192_168_99.yml

---
network:
  net_addr: 99

group_vars / net_192_168_123.yml

---
network:
  net_addr: 123

playbook.yml

---
- name: Foo playbook 
  hosts: 127.0.0.1
  become: false
   tasks:
    - name: Debug
      debug:
        msg: "{{ groups[item] | map('extract', hostvars, 'network') | list }}"
      loop: "{{ groups | select('match','net_.*') | list }}"

Я ожидал увидеть net_addr: 123 где-то в выводе, но всегда получаю net_addr: 99

Большое спасибо.

Answer 1

После долгих исследований я пришел к такому подходу к созданию групповых переменных, которых я ожидал. Я взял части ответа из множества источников, которые, к сожалению, больше не могу назвать подробно.
