Question

我有一个来自PowerShell脚本的返回值数组，我想只有当数组中的所有项都是0时才执行命令。我有这个：

- name: check if computer is running DC services
  raw: Get-Service -name {{item}}
  with_items:
    - "adws"
    - "kdc"
    - "netlogon"
  register: services
  # ignore_errors: yes
  failed_when: services.stderr and 'Cannot find any service with service name ' not in services.stderr
  changed_when: False

- name: debug services
  debug:
    var=services

- name: copy check_ad.exe to DCs
  win_copy: src=check_ad.exe dest='{{nagios_client_install_path}}\\check_ad.exe'
  tags: ['win-nagios-client']
  when: item.rc == 0

但如果任何服务正在运行，则会运行copy check_ad.exe。如何在所有服务正在运行时将其更改为仅运行？

调试信息在这里：

由于rc值是整数，您可以将它们相加并将结果与0进行比较：

- name: copy check_ad.exe to DCs
  win_copy: src=check_ad.exe dest='{{nagios_client_install_path}}\\check_ad.exe'
  tags: ['win-nagios-client']
  when: services.results | map(attribute='rc') | sum == 0

更通用的方法（不仅仅是整数）是使用difference filter删除所有出现的0（从上面的映射rc的结果列表中删除）并检查其余清单的大小。

如果原始列表包含其他元素，则结果值为正。

检查列表是否仅由Ansible中的值等于0组成
