Ansible的`set_fact`根本不工作

Question

我正在尝试设置一个Ansible剧本，它将在Windows上运行一个PowerShell脚本，并在其上set_fact结果，并使用setup返回所有事实。

这是我的playbook.yml

---
- hosts: windows
  gather_facts: no
  tasks: 
    - name: Get a PowerShell script to work
      script: files/gather-windows-facts.ps1
      register: ps1_script
    - debug: var=ps1_script

    - name: Put the PS output into the host's facts
      set_fact:
        string: "HALLO WELT!"
        json: "{{ ps1_script.stdout }}"
        ansible_fqdn: EXISTING_VARIABLE_CHANGED
      register: store_facts
    - debug: var=store_facts

    - name: Get the facts from the host
      setup: {}
      register: setup_step
    - debug: var=setup_step

我的PowerShell脚本files/gather-windows-facts.ps1目前只是一个虚拟脚本；它设置一个JSON变量并将其放在stdout上：

ConvertFrom-Json "{HELLO: 'WORLD!'}" | Set-Variable object

Get-Variable object -ValueOnly | ConvertTo-Json

我正在运行这个脚本：

ansible-playbook -i inventory playbook.yml

我得到的是：

注意，json和string都不存在，它们的预期值也不存在；ansible_fqdn也没有按预期更改它的值。

我知道set_fact不应该永久地在主机上设置事实，但它们不应该在一个剧本中持久存在吗？

setup不包括您设置的事实，只包括默认设置。
