地形Azurerm_virtual_machine_extension

问题描述

我正在使用 azurerm_virtual_machine_extension 在Azure中引导一些虚拟机.

I'm using azurerm_virtual_machine_extension to bootstrap some virtual machines in azure.

我发现的所有示例都使用类似的东西显示:

All examples i've found show using something similar to:

settings = <<SETTINGS
    {
    "fileUris": [ "https://my.bootstrapscript.com/script.sh}" ],
    "commandToExecute": "bash script.sh"
    }
SETTINGS

虽然可行，但我的问题是我必须公开托管 script 与 fileUris 一起使用.设置中是否有允许我从terraform文件夹发送本地文件内容的选项?

While this works, my issue is i'm having to publicly host script for use with fileUris. Is there an option within settings that will allow me to send local file contents from my terraform folder?

类似的东西:

settings = <<SETTINGS
    {
    "file": [ ${file("./script.txt")} ],
    "commandToExecute": "bash script.sh"
    }
SETTINGS

谢谢.

推荐答案

是的！

简介

在protected_settings中，使用脚本".

Yes We Can!

Introduction

In protected_settings, use "script".

terrain脚本

provider "azurerm" {
}

resource "azurerm_virtual_machine_extension" "vmext" {
    resource_group_name     = "${var.resource_group_name}"
    location                = "${var.location}"
    name                    = "${var.hostname}-vmext"

    virtual_machine_name = "${var.hostname}"
    publisher            = "Microsoft.Azure.Extensions"
    type                 = "CustomScript"
    type_handler_version = "2.0"

    protected_settings = <<PROT
    {
        "script": "${base64encode(file(var.scfile))}"
    }
    PROT
}

变量

variable resource_group_name {
    type = string
    default = "ORA"
}

variable location {
    type = string
    default = "eastus"
}

variable hostname {
    type = string
    default = "ora"
}

variable scfile{
    type = string
    default = "yum.bash"
}

bash脚本

#!/bin/bash

mkdir -p ~/download
cd ~/download
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm
yum -y install cowsay
cowsay ExaGridDba

输出

应用

[terraform@terra stackoverflow]$ terraform apply

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # azurerm_virtual_machine_extension.vmex0 will be created
  + resource "azurerm_virtual_machine_extension" "vmex0" {
      + id                   = (known after apply)
      + location             = "eastus"
      + name                 = "ora-vmext"
      + protected_settings   = (sensitive value)
      + publisher            = "Microsoft.Azure.Extensions"
      + resource_group_name  = "ORA"
      + tags                 = (known after apply)
      + type                 = "CustomScript"
      + type_handler_version = "2.0"
      + virtual_machine_name = "ora"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

备注

1. 脚本大小限制为262144字节base64编码，或196608字节.
2. #！"确定口译员.#！/bin/python"将启动python脚本.
3. 不需要这些azurerm_virtual_machine_extension参数:
   • 设置
   • fileUris
   • commandToExecute
   • storageAccountName
   • storageAccountKey

结论

在Azure VM中，可以在不引用Blob存储帐户的情况下运行脚本.

Conclusion

In Azure VM, it is possible to run a script without referring to a blob storage account.
