Ansible-从dict on value中提取记录

在ansible中，我有一个目录，如：

- { name: "a" }
- { name: "b", cond: true }

我想在cond未定义或为false时提取姓名列表（1），在cond为true或未定义时提取姓名列表（2）：

怎么做？我没有找到

谢谢

您可以使用

json\u查询

过滤器：

---
- hosts: localhost
  gather_facts: false
  vars:
    mylist:
      - name: a
      - name: b
        cond: true

  tasks:
    - set_fact:
        true_or_unset: "{{ mylist|json_query('[?cond == null || cond].[name]') }}"
        false_or_unset: "{{ mylist|json_query('[?cond == null || !cond].[name]') }}"

    - debug:
        msg:
          true_or_unset: "{{ true_or_unset }}"
          false_or_unset: "{{ false_or_unset }}"

产生：

PLAY [localhost] ******************************************************************************

TASK [set_fact] *******************************************************************************
ok: [localhost]

TASK [debug] **********************************************************************************
ok: [localhost] => {
    "msg": {
        "false_or_unset": [
            [
                "a"
            ]
        ], 
        "true_or_unset": [
            [
                "a"
            ], 
            [
                "b"
            ]
        ]
    }
}

PLAY RECAP ************************************************************************************
localhost                  : ok=2    changed=0    unreachable=0    failed=0

谢谢，这正是我想要的！
