我正在使用azurerm_virtual_machine_extension在Azure中引导一些虚拟机。
我发现的所有示例都使用类似的内容显示：
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以便与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？
类似的东西：
settings = <<SETTINGS
{
"file": [ ${file("./script.txt")} ],
"commandToExecute": "bash script.sh"
}
SETTINGS
谢谢。

在protected_settings中，使用“脚本”。
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

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.
Enter a value: yes

在Azure VM中，可以在不引用Blob存储帐户的情况下运行脚本。
答案 1 :(得分：0)
不，您不能这样做，您有2种选择：
Microsoft.Compute/virtualMachineScaleSets/virtualMachines/runCommand/action和Microsoft.Compute/virtualMachines/runCommand/action在vm \ vmss实例上从本地控制台运行脚本（很确定terrafrom不会公开此api调用，但是powershell \ azu cli可以这样做）。
