使用 Ansible 在 vCenter 服务器上创建文件夹

Question

• 问题说明：
  1. 给定一个文件夹名称，检查它是否存在于 vCenter Server 上，如果不存在，则创建它。
  2. 从此文件夹下的模板中克隆虚拟机。

例如，我想在“管理员桌面”下克隆一个虚拟机，如下图所示： Click here to see the image

下面的脚本是从指定模板克隆虚拟机并将虚拟机放入指定文件夹。但当该文件夹在 VCenter 服务器上不存在时失败：

---
- hosts: localhost
  connection: local
  sudo: false
  user: root
  gather_facts: false
  serial: 1

  vars_files:
    - createVmVars.yml

  tasks:
    - name: Deploying VM from template.
      vsphere_guest:
        vcenter_hostname: "{{vcenter_hostname}}"
        username: "{{vcenter_username}}"
        password: "{{vcenter_password}}"
        guest: "{{guest_name}}"
        from_template: yes
        template_src: "{{template_src}}"
        cluster: "{{cluster}}"
        resource_pool: "{{resource_pool}}"
        vm_extra_config:
          folder: "{{folder_name}}"

需要帮助使这个脚本灵活，以便当文件夹不存在时，它应该创建提到的文件夹，然后在这个文件夹下克隆虚拟机。

您可以使用这个 Ansible 模块在 vsphere 中创建文件夹：

#!/usr/bin/python
# -*- coding: utf-8 -*-

notes:
  - This module ought ot be run from a system which can access vsphere directly
