如何使用 Ansible 为在 VCenter 上创建的虚拟机分配 IP 地址？

Question

问题陈述：
1. 从模板克隆 VM。
2. 为创建的 VM 分配 IP 地址。

我正在使用 Ansible 来完成这项工作。以下是从指定模板克隆 VM 的脚本：

---
- 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}}"

我想扩展此脚本以将 IP 地址（和其他 n/w 配置）分配给新创建的 VM。

Answer 1

您可以在 vm_extra_config

中指定静态 IP 地址

    .
    .
    .
    cluster: "{{cluster}}"
    resource_pool: "{{resource_pool}}"
    vm_extra_config:
      folder: "{{folder_name}}"
      ip_address: "{{my_static_ip}}"
    .
    .

虽然我找不到其他网络设置，例如网络掩码和网关。 vsphere_guest 或 pysphere 模块

上都没有这样的描述

Answer 2

经过大量搜索，我现在只剩下使用 python 直接将网络配置写入适当文件的唯一选择。以下对我来说很好用。您可以使用带有所需参数的 Shell 模块从 Ansible 运行此脚本。根据您的需要进行更改：

import sys
import shutil
import os

                self.sdns=""
                self.ip=""
                self.netmask=""

                                "/etc/HOSTNAME"
                                ]

        def writeIntoFile(self,filename,s,mode):
                f=open(filename,mode)
