如何在ansible中重命名或重新映射键

Question

我正在尝试将 geerlingguy 的this repo （谢谢！）与我的实际东西一起使用
但是我的文件中的变量不一样并且无法更改它们，因为它们已被其他任务使用...
我的结构其实是这样的：

apache2:
  vhost:
  - name: toto.com
    add_vhost: true
    add_ssl: true
  - name: AAA.toto.com
    add_vhost: true
    add_ssl: true
  - name: BBB.toto.com
    add_vhost: true
    add_ssl: true
  - name: CCC.toto.com
    add_vhost: true
    add_ssl: true 

我复制此任务以使用我的变量 (source) 但我的变量名为 cert_item.name 我必须翻译成cert_item.domains 来处理in this file 工作的任务。

- include_tasks: create-cert-standalone.yml
  with_items:
  - "{{ apache2.vhost }}"
  when:
  - certbot_create_if_missing
  - certbot_create_method == 'standalone'
  - cert_item_apache2.add_ssl | d(true)
  loop_control:
    loop_var: cert_item

我怎样才能将cert_item.name 传递给任务并让他阅读cert_item.domains？

您可以在之前创建列表 certbot_certs 以包含任务 create-cert-standalone.yml

---
- hosts: localhost
  gather_facts: false

  vars:
    certbot_create_if_missing: true
    certbot_create_method: "standalone"
    apache2:
      vhost:
        - name: toto.com
          add_vhost: true
          add_ssl: true
        - name: AAA.toto.com
          add_vhost: true
          add_ssl: true
        - name: BBB.toto.com
          add_vhost: true
          add_ssl: true
        - name: CCC.toto.com
          add_vhost: true
          add_ssl: true

  tasks:

    - name: SET_FACTS | Populate attribute domains
      vars:
        certbot_entry: "{{ item.name }}"
      set_fact:
        certbot_certs: "{{ certbot_certs |default([]) + [certbot_entry] }}"
      loop: "{{ apache2.vhost }}"
      when:
        - certbot_create_if_missing
        - certbot_create_method == 'standalone'
        - item.add_ssl | d(true)


    - include_tasks: create-cert-standalone.yml
      with_items: "{{ certbot_certs }}"
      when:
        - certbot_create_if_missing
        - certbot_create_method == 'standalone'
      loop_control:
        loop_var: cert_item

我的 create-cert-standalone.yml 文件：

---
- name: "Create cert standalone {{ cert_item }}"
  debug:
     msg: "{{ cert_item }}"

这里是输出：
