Ansible:如何从列表字典中提取值 [英] Ansible: How to extract values from a dictionary of lists

问题描述

我正在尝试从字典列表中获取值，但无法获得确切的输出，这是必需的

I'm trying to fetch the values from list of dict but unable to get the exact output, which is required

将Linux服务器与已安装的ansible 2.7.5& jinja2 2.7.2.

Using Linux server with installed versions of ansible 2.7.5 & jinja2 2.7.2 .

下面的是dict值列表.

DOMAIN_GROUPS_ASSIGNMENT:


CACHE01:
    - domain_group: DG1
      is_active: true
    - domain_group: DG2
      is_active: true
    - domain_group: DG3
      is_active: true
  CACHE02:
    - domain_group: DG4
      is_active: true
    - domain_group: DG5
      is_active: true
    - domain_group: DG6
      is_active: true

  SCACHE01:
    - domain_group: DG1
      is_active: false
    - domain_group: DG2
      is_active: false
    - domain_group: DG3
      is_active: true
  SCACHE02:
    - domain_group: DG4
      is_active: false
    - domain_group: DG5
      is_active: false
    - domain_group: DG6
      is_active: false

到目前为止，尝试使用以下代码:

So far trying with the below code:

- debug:
      msg: "KEY: {{ item.key }}, VALUE: {{ item.value }}"
    loop: "{{ lookup('dict', DOMAIN_GROUPS_ASSIGNMENT) }}"

我得到的输出是:

必需的输出:

结果应为dict格式，并应存储在一个变量中.

Result should be in dict format and should be stored in one variable.

我希望列表或字典格式的内容如下所示:

I expect something like below in list or dict format:

CACHE01:是，CACHE02:是，SCACHE01:否，SCACHE02:否

以上值应存储在一个变量中.

The above values should get stored in one variable.

推荐答案

您必须为结果选择正确的value:

You have to select the right value for your result:

tasks:
- name: DEBUG
  debug:
    msg: 'KEY: {{ item.key }}, VALUE: {{ item.value.0.is_active }}'
  loop: '{{ lookup("dict", DOMAIN_GROUPS_ASSIGNMENT) }}'
