Terraform模块- error您的基础结构与配置匹配

Question

我正在尝试使用地形模块并创建了一个非常简单的模块。结构如下:

├───dev
│       dev.tfvars
│       main.tf
│       output.tf
│       variables.tf
│
└───modules
└───instances
main.tf
output.tf
variables.tf
versions.tf
terraform init
PS C:Users61421githubIAC-TFdev> terraform init
Initializing modules...
- ec2_create in ..modulesinstances
Initializing the backend...
Initializing provider plugins...
- Finding hashicorp/aws versions matching "~> 4.17.1"...
- Installing hashicorp/aws v4.17.1...
- Installed hashicorp/aws v4.17.1 (signed by HashiCorp)
terraform plan
PS C:Users61421githubIAC-TFdev> terraform plan
No changes. Your infrastructure matches the configuration.

我正在从我的DEV执行这些命令(我计划在不同的目录中构建prod)。

dev.tfvars
instance_type    = "t2.micro"
instance_keypair = "user001"
no_of_instances  = 1
ami_id           = "ami-0c6120f461d6b39e9"

main.tf
provider "aws" {
region = "ap-southeast-2"
}
module "ec2_create" {
source        = "../modules/instances"
ami           = var.ami_id
instance_type = var.instance_type
count         = var.no_of_instances
}
variables.tf
variable "no_of_instances" {
description = "Number of Instances"
type        = number
default     = 0
}
variable "ami_id" {
description = "ami_id"
type        = string
default     = ""
}
variable "instance_type" {
description = "instance_type"
type        = string
default     = ""
}

我的示例模块如下。

main.tf
resource "aws_instance" "web" {
ami = var.ami
instance_type = var.instance_type
count = var.no_of_instances
}
variables.tf
variable "ami" {
description = "ID of AMI to use for the instance"
type        = string
default     = ""
}
variable "instance_type" {
description = "instance_type of AMI to use for the instance"
type        = string
default     = ""
}
variable "no_of_instances" {
description = "Number of Instances"
type        = number
default     = 1
}
versions.tf
terraform {
required_version = "~> 1.1.7" # which means any version equal & above 4.17.1 like 4.17.2
required_providers {
aws = {
source  = "hashicorp/aws"
version = "~> 4.17.1"
}
}

看起来没有创建任何东西，我用一个没有模块的文件尝试了相同的资源aws_instance，它创建了。看起来我在调用模块时遗漏了一些东西。谢谢你的帮助。我是新来的。

这很可能是因为您的no_of_instances默认为0。因此不需要创建资源。

要使用你的dev.tfvars，你必须显式地传递这个文件:

terraform plan -var-file=dev.tfvars
