Terraform-在一个事务中创建资源/设置回滚策略

在我的一个网络中,我不小心配置了错误的值,导致 资源创建失败。

但我更希望所有流程都按如下方式执行 一笔交易 .

Terraform在遇到错误时不会自动回滚。 相反,您的地形状态文件已使用任何 已成功完成的资源。请解决上面的错误

我的问题是: 在某些资源已创建但某些资源已失败的情况下?

下面是一个简单的例子来重现这个问题。

在局部变量中 'az_list' 仅将值从“名称”更改为“区域ID”:

az_list = "${data.aws_availability_zones.available.zone_ids}"

资源.tf:

provider "aws" {
  region = "${var.region}"
}

### Local data ###
data "aws_availability_zones" "available" {}

locals {
  #In order to reproduce an error: Change 'names' to 'zone_ids'
  az_list = "${data.aws_availability_zones.available.names}"  
}

### Vpc ###
resource "aws_vpc" "base_vpc" {
  cidr_block           = "${var.cidr}"
  instance_tenancy     = "default"
  enable_dns_hostnames = "false"
  enable_dns_support   = "true"
}

### Subnets ###
resource "aws_subnet" "private" {
  vpc_id            = "${aws_vpc.base_vpc.id}"
  cidr_block        = "${cidrsubnet( var.cidr, 8, count.index + 1 + length(local.az_list) )}"
  availability_zone = "${element(local.az_list, count.index)}"
  count             = 2
}

resource "aws_subnet" "public" {
  vpc_id            = "${aws_vpc.base_vpc.id}"
  cidr_block        = "${cidrsubnet(var.cidr, 8, count.index + 1)}"
  availability_zone = "${element(local.az_list, count.index)}"
  count             = 2
  map_public_ip_on_launch = true
}

变量.tf:

variable "region" {
  description = "Name of region"
  default     = "ap-south-1"
}


variable "cidr" {
  description = "The CIDR block for the VPC"
  default     = "10.0.0.0/16"
}
