Ansible - 如何将多个不同的列表合并到任务循环中使用

Question

我有如下 3 个列表

users:
  - "['user1', 'user2']"
permissions:
  - "[['Read'], ['Read', 'Write']]"
topics:
  - "[['Topic1', 'Topic2'], ['Topic3', 'Topic4', 'Topic5']]"

我想组合成类似这样的结构

  combined_lists:
    [
        {'user1', 'Read','Topic1'},
        {'user1', 'Read','Topic2'},
        {'user2', 'Read','Topic3'},
        {'user2', 'Read','Topic4'},
        {'user2', 'Read','Topic5'},
        {'user2', 'Write','Topic3'},
        {'user2', 'Write','Topic4'},
        {'user2', 'Write','Topic5'}
    ]

这样我就可以在下面的任务中使用它

- name: Generate ACL command and run
  shell: |
    echo " kafka-acls --bootstrap-server broker1:9092 --command-config /kafka/configs/client.properties --add --allow-principal User:{{ item.0 }} --operation {{ item.1 }} --topic {{ item.2 }}"
  loop:
      "{{ combined_lists }}"

有人可以建议我应该使用或查看哪个模块来组合列表，这些列表是可用于生成和执行 kafka-acl 命令的格式的列表列表？我试图查看笛卡尔模块，但无法使其以这种方式工作。

感谢任何有关要查看哪些模块以实现结果的指示。

谢谢

你需要处理几个 set_facts 循环：

---
- hosts: localhost
  gather_facts: false

  vars:
    users: [ "user1", "user2" ]
    permissions: [ "Read", [ "Read", "Write"]]
    topics: [[ "Topic1", "Topic2"], ["Topic3", "Topic4", "Topic5"]]

  tasks:

    - name: SET_FACTS | Combine users and permissions
      vars:
        user: "{{ users[my_idx] }}"
        permission: "{% if item | type_debug == 'list' %}{{ item }}{% else %}{{ [item] }}{% endif %}"
      set_fact:
        combined_up: "{{ combined_up | default([]) + [[user] | product(permission) | list] }}"
      loop: "{{ permissions }}"
      loop_control:
        index_var: my_idx

    - name: SET_FACTS | Combine users, permissions with topics
      vars:
        userpermission: "{{ combined_up[my_idx] }}"
        topic: "{% if item | type_debug == 'list' %}{{ item }}{% else %}{{ [item] }}{% endif %}"
      set_fact:
        combined_upt: "{{ combined_upt | default([]) + userpermission | product(topic) | list }}"
      loop: "{{ topics }}"
      loop_control:
        index_var: my_idx

    - name: SET_FACTS | Create list of dictionary objects
      set_fact:
        combined_listd: "{{ combined_listd | default([]) + [{ 'user': item[0][0], 'permission': item[0][1], 'topic': item[1] }] }}"
      loop: "{{ combined_upt }}"

    - name: SET_FACTS | Create list of lists
      set_fact:
        combined_lists: "{{ combined_lists | default([]) + [[ item[0][0], item[0][1], item[1] ]] }}"
      loop: "{{ combined_upt }}"

    - name: DEBUG | list of dictionary objects
      debug:
        msg: "{{ item.user }} - {{ item.permission }} - {{ item.topic }}"
      loop: "{{ combined_listd }}"

    - name: DEBUG | list of lists
      debug:
        msg: "{{ item[0] }} - {{ item[1] }} - {{ item[2] }}"
      loop: "{{ combined_lists }}"

这里是输出：
