【问题描述】：

我有以下 Ansible 代码，它从 azure 中的“az”命令读取输入。我基本上想用它来查看资源组何时完成创建我的 VMS。

#!/usr/local/bin/ansible-playbook
---
- name: Firewall Rules
  hosts: localhost
  connection: local
  vars:
    iscbr: false

  tasks:
  - name: Register status of group x
    command: az group deployment list -g Tes1Pod
    register: azdeployment

  - name:
    set_fact:
      provisioningstatus: "{{ (azdeployment.stdout|from_json) }}"


  - name: debug provisioningstatus
    debug:
      var: "{{item}}"
    with_items: "{{provisioningstatus.properties}}"


  # - name: Debug stuff
  #   debug:
  #     msg: " item.provisioningState"
  #   with_items: "{{provisioningstatus"

  # - debug: var=provisioningstatus

这是 Ansible 调试的输出：

}

所以基本上我想获取每个项目的 properties.Provisioningstate（成功与否）。即使我试图勇敢地这样做，我也无法对这些进行映射。

ansible 的输出转换为 JSON，但我无法选择或映射属性。我总是收到关于各种无法正常工作的错误（也就是找不到属性等等）。

主要错误是我每次都无法提取provisioningstatus.properties.provisioningState，我收到“未定义变量”消息。

ok: [localhost] => {
    "provisioningstatus.properties": "VARIABLE IS NOT DEFINED!"
}

【问题讨论】：

你能把这里的示例输出替换为一个显示provisioningstatus 变量内容的ansible debug 任务的输出吗？您能否准确地展示您遇到的故障类型（具体的错误消息和生成它们的任务）？
我会这样做的。大约一个小时后可以完成一些操作
完成。我已按要求更新了问题。

【解决方案1】：

你可以试试这个：

- debug:
    msg: "{{ item.properties.provisioningState }}"
  with_items: "{{ provisioningstatus }}"

【解决方案2】：

虽然不能完全回答您的问题，但我建议您在 ansible 配置中使用 arm 模板部署步骤。他们为你跟踪状态并且是幂等的（这就是你想要的）。

- name: Deploy Something
  azure_rm_deployment:
    deployment_name: SomeDeploymentName
    resource_group_name: "{{ variable }}"
    location: '{{ location }}'
    template: "{{ lookup('file', './templates/azuredeploy.json') }}"
    parameters:
      deploymentPrefix:
        value: "{{ variable }}"
      redisCacheNames:
        value: "xxx"
