azure - 使用azure terraform在3个azure虚拟机中执行shell脚本

转载作者：行者123 更新时间：2023-12-03 06:34:09

下面的代码创建了 3 个 linux ubuntu azure 虚拟机。同时我想在这 3 个虚拟机中执行 shell 脚本。为此，我使用下面的代码，但收到以下错误，基本上是使用 filebase64 来执行代码，但它的不工作。有人可以检查一下并让我知道问题

最佳答案

删除该 block

data "template_file" "config" {
  template = file("${path.module}/script.sh")
}

并替换下面的代码

# Resource: Azure Linux Virtual Machine
resource "azurerm_linux_virtual_machine" "mylinuxvm" {
[...
custom_data  = filebase64(data.template_file.config.rendered)
...]
}

与

# Resource: Azure Linux Virtual Machine
resource "azurerm_linux_virtual_machine" "mylinuxvm" {
[...
custom_data  = filebase64("${path.module}/script.sh")
...]
}

作为引用，您的结果将是

#!/bin/bash

printf "Hello World"
mkdir -p /tmp/user-data
