尝试编写一个playbook,检查一组文件在一组服务器(包括Linux和Windows主机)上是否存在,如果存在,则替换这些文件。
以下是我已经编写的内容:
当我在Windows和Linux主机上运行此测试时,会得到以下结果:
然而,即使条件的第一部分为假,Ansible 仍然似乎会检查 item.stat 字段。或者我的基本方法是错误的,我应该将这些任务拆分成不同的 playbooks 吗?
以下是我已经编写的内容:
---
- hosts: "{{hosts}}"
vars:
scripts:
- check_blackout.pl
- check_empty.pl
tasks:
- name: windows stat
with_items: "{{scripts}}"
win_stat: path=D:\scripts\{{item}}
register: windows_stat
when: "'windows' in group_names"
- name: other stat
with_items: "{{scripts}}"
stat: path=/usr/local/bin/{{item}}
register: other_stat
remote_user: "{{script_owner | default(ansible_user)}}"
when: "'windows' not in group_names"
- name: windows debug
with_items: "{{windows_stat.results}}"
debug: var={{item.item}}
when: "{{item.stat.exists}}"
- name: other debug
with_items: "{{other_stat.results}}"
debug: var={{item.item}}
when: "{{item.stat.exists}}"
...
当我在Windows和Linux主机上运行此测试时,会得到以下结果:
[ansible@vmhklftpscdv1 ~]$ ansible-playbook test.yml -e "hosts=vmhkge1jasdev01,jdeesbkup" --ask-vault-pass

有什么想法可以让这个工作起来吗?
我尝试了各种组合,包括在检查结果之前检查组成员身份:
when: "'windows' in group_names and {{item.stat.exists}}"
然而,即使条件的第一部分为假,Ansible 仍然似乎会检查 item.stat 字段。或者我的基本方法是错误的,我应该将这些任务拆分成不同的 playbooks 吗?

,你却回复了一个普通的错误信息。 然后你让我从头开始逐步调试一切,而事实上它已经可以工作了。 - techraf
