Question

我有一个简单的Powershell脚本，可以检查两件事情并将结果写入输出。我的想法是在Ansible Playbook中使用该输出作为将用于重启机器的变量，或者不使用（但在下面的示例中，我有一个PING测试命令）。

我的PS1

#Change computer description
$CDesc = Get-Item -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\"
If($CDesc.GetValue("srvcomment") -eq $null) {
    New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\" -Name "srvcomment" -Value "PROD | AZI | V | APPLICA | SQL" -PropertyType String
} else {
    $step1 = Write-Output "Step1"
}

#Check if CD drive is available
$CDletter = Get-WmiObject -Class Win32_CDROMDrive | select -ExpandProperty Drive
If($CDletter -eq $null) {
    $step2 = Write-Output "Step2"
}



if (($step1) -and ($step2)) {Write-Host "already_updated"}

我的手册：

# Run post build scripts on machines taggedd with AnsibleVM1 from commad line variable with "{{ hosts }}"
# ansible-playbook test.yml -i azure_rm.py --extra-vars "hosts=displayName_AnsibleVM1" --ask-vault-pass -vvvv

- hosts: "{{ hosts }}"
  gather_facts: no

  vars_files:
   - ./vars/vault.yml
   - ./vars/vars.yml

  tasks:
   - include_vars: vault.yml
   - name: test script
     script: ./files/test.ps1
     register: result

   - set_fact: machineId={{result.stdout_lines.0}}

   - win_ping:
       when: machineId.already_ASDF

然而，PING（或即将成为REBOOT）模块仍在运行。这是我的输出：

任何想法我做错了什么？

如果你想匹配字符串（例如，检查脚本的输出值是否已“更新”），你可以这样做：

- win_ping: when: machineId == 'already_updated' machineId没有属性，它是一个简单的字符串值。

为了保存步骤，您还可以： - win_ping: when: result.stdout_lines[0] == 'already_updated'

为了构建更复杂的Powershell逻辑并仍然与Ansible交互，你基本上有两个选择：

让你的Powershell脚本输出json（使用“Convertto-json”cmdlet和Write-Output）并使用Ansible的内置json解析器来解析它
在Powershell中编写Ansible模块。
