azure - 使用 ansible 部署多个虚拟机

问题描述

我正在学习 ansible 在 azure 上创建 Linux VM，并在此链接（https://docs.microsoft.com/en-us/azure/developer/ansible/vm-configure?tabs=ansible）中使用了此示例剧本在 azure 上创建一个 VM。如果我想用 ansible-playbook 完全像这样部署 10 个 VM，我应该怎么做？请帮忙。提前致谢

更新：我尝试过这样，但创建两个公共 IP 地址后脚本失败。

- name: Create Azure VM
  hosts: localhost
  connection: local
  tasks:
  - name: Create resource group to hold VM
    azure_rm_resourcegroup:
      name: TestingResource

  - name: Create virtual network

  - name: Create public IP address

    loop:
       - testingpublicIP2
       - testingpublicIP3  
    register: output_ip_address
  #- name: Dump public IP for VM which will be created
    #debug:
      #msg: "The public IP is {{ output_ip_address.state.ip_address }}."

解决方案

您可以使用loops函数通过ansible创建多个VM，如您在问题中所示，但您最好使用列表变量进行循环，这样您就不需要每次都编写所有元素。并且这些变量还可以用于在代码中多次使用的资源组名称、位置等其他内容。这是示例：

- hosts: localhost
  vars:
    resource_group: myResourceGroup
    ...
  tasks:
  - name: Create resource group to hold VM
    azure_rm_resourcegroup:
      name: "{{ resource_group }}"
      location: eastus
  ...

以及循环的变量：

loop: "{{ var_list }}"
