Ansible 尝试在playbook中注册输出时未定义变量

我试图注册一个变量，并将其输出到F5池的查询中，但出现以下错误：

"<type 'list'>": "VARIABLE IS NOT DEFINED!",

您正在使用带有选项

var:

的

debug:

模块，这需要一个变量，而不是jinja2模板

因此，要么将其更改为：

debug:
  var: item.members

或

---

正如@dgw所说，问题在于

debug

模块的

var

选项

这个剧本的作用是：

  - name: test rejectattr
    hosts: localhost
    gather_facts: no

    vars:
      members:
        - { name: "one", state: "present" }
        - { name: "two", state: "absent" }
        - { name: "three", state: "present" }

    tasks:

      - name: FACTS OUTPUT
        debug:
          msg: "{{ members | rejectattr('state', 'match', '^present$') | map(attribute='name') | list }}"

---

谢谢你的回复。我会进一步调查的。 除此之外，我想我还可以用另一种方法解决这个问题

    - name: FACTS OUTPUT
  set_fact:
    listado: "{{ item.members | rejectattr('state', 'match', '^present$') | map(attribute='name') | list }}"
  with_items: "{{ bigip_device_facts.ltm_pools }}"
  when: item.full_path  == "/Common/mypool"
- debug: msg={{ listado }}
  register: jkout

- name: Set a variable
  debug:
    msg: "jkvar={{ jkout }}"

这样做对吗？ 谢谢

  - name: test rejectattr
    hosts: localhost
    gather_facts: no

    vars:
      members:
        - { name: "one", state: "present" }
        - { name: "two", state: "absent" }
        - { name: "three", state: "present" }

    tasks:

      - name: FACTS OUTPUT
        debug:
          msg: "{{ members | rejectattr('state', 'match', '^present$') | map(attribute='name') | list }}"

    - name: FACTS OUTPUT
  set_fact:
    listado: "{{ item.members | rejectattr('state', 'match', '^present$') | map(attribute='name') | list }}"
  with_items: "{{ bigip_device_facts.ltm_pools }}"
  when: item.full_path  == "/Common/mypool"
- debug: msg={{ listado }}
  register: jkout

- name: Set a variable
  debug:
    msg: "jkvar={{ jkout }}"
