尝试在剧本中注册输出时未定义变量

Question

我正在尝试将一个变量与F5池的查询的输出一起注册，我得到了这个错误：

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

我做错了什么？感谢您的帮助。谢谢!

- name: GRAB F5 FACTS
  hosts: f5
  connection: local
  gather_facts: no
  tasks:
    - name: Collect BIG-IP facts
      bigip_device_facts:
        gather_subset: ltm-pools
        provider: "{{ prov }}"
      register: bigip_device_facts

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

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

Answer 1

您正在使用带有选项var:的debug:模块，并且这需要一个变量，而不是一个jinja2模板。

因此，要么将其更改为：

debug:
  var: item.members

或

debug:
  msg: "{{ item.members }}"

Answer 2

正如@dgw所说，问题出在debug模块的var选项上。

https://docs.ansible.com/ansible/latest/modules/debug_module.html#parameters

此攻略适用于：

  - 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 }}"

Answer 3

感谢您的回复。我会进一步调查的。除此之外，我想我还能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 }}"

这是一种正确的做法吗？谢谢！！
