使用date.stdout过滤器和stdout中的变量的Ansible剧本

我正在尝试运行此任务:

---
- name: "{{ BANNER }}"

  shell: "rpm -qf /etc/issue"
  register: rpm
  changed_when: False
  ignore_errors: True

- shell: 'rpm -q -i "{{ rpm.stdout }}" | grep "Install Date:" | awk ''{ print $4 " " $5 " " $6 }'''
  register: rpm
  changed_when: False
  ignore_errors: True

- shell: 'date -d "{{ rpm.stdout }}" +''%Y-%d-%m'''
  register: date
  changed_when: False
  ignore_errors: True

- debug: var=date.stdout

- debug: var={{ (( date.stdout | to_datetime('%Y-%m-%d')) - ("2020-12-25" | to_datetime('%Y-%m-%d'))).days  }}

基本上,我需要传递data.stdout中包含的字符串以过滤to_datetime以进行日期减法,但是我收到此错误:

TASK [RH7-008 : debug] **********************************************************************************************************************************************
ok: [192.168.56.1] => {
    "date.stdout": "2019-14-03"
}

TASK [RH7-008 : debug] **********************************************************************************************************************************************

        to retry, use: --limit @/root/ansible/main.retry

date.stdout中指定的格式输入相比,to_datetime('%Y-%m-%d')中包含的格式输入似乎是错误的。我想念什么?也许date.stdout中有些奇怪的人物?

您要to_datetime解析格式为%Y-%m-%d的日期。

您正在传递2019-14-03形式的数据。

一年中没有14个月。

您希望to_datetime的format参数与您为date命令提供的format参数匹配:

to_datetime('%Y-%d-%m')

进行制作(为清晰起见,对其进行了略微重新格式化,并更改了硬编码日期以匹配您的格式):

- debug:
    var: >-
      (
      (date.stdout | to_datetime('%Y-%d-%m')) -
      ("2020-25-12" | to_datetime('%Y-%d-%m'))
      ).days

或者,如果您确实需要date,则将参数交换为%Y-%m-%d命令。只要确保它们匹配即可。
