Question

我是Terraform的新手，在尝试使用.tf文件的环境变量时遇到了一些问题，我尝试使用terraform.tfvars / variables.tf。

./terraform apply -var-file="terraform.tfvars"
Failed to load root config module: Error parsing variables.tf: At 54:17: illegal char

我在这里缺少什么？

Terraform版本：Terraform v0.9.2

main.tf：

provider "aws" {
  access_key = "${var.aws_access_key}"
  secret_key = "${var.aws_secret_key}"
  region = "${var.aws_region}"
  allowed_account_ids = ["${var.aws_account_id}"]
}

resource "aws_instance" "db" {

  ami           = "ami-49c9295"
  instance_type = "t2.micro"

  tags {
    Name = "test"
  }

  connection {
   user = "ubuntu"
  }

  security_groups = ["sg-ccc943b0"]
  availability_zone = "${var.availability_zone}"
  subnet_id = "${var.subnet_id}"
}

terraform.tfvars：

aws_profile = "default"
aws_access_key = "xxxxxx"
aws_secret_key = "xxxxxx"
aws_account_id = "xxxxxx"
key_name = "keyname"
key_path = "/home/user/.ssh/user.pem"
aws_region = "us-east-1"
subnet_id = "subnet-51997e7a"
vpc_security_group_ids = "mysql"
instance_type = "t2.xlarge"
availability_zone = "us-east-1a"

variables.tf：

variable "key_name" {
    description = "Name of the SSH keypair to use in AWS."
    default     = "keypairname"
}

variable "key_path" {
    description = "Path to the private portion of the SSH key specified."
    default     = "/home/user/.ssh/mypem.pem"
}

variable "aws_region" {
    description = "AWS region to launch servers."
    default     = "us-east-1"
}

variable "aws_access_key" {
    decscription = "AWS Access Key"
    default     = "xxxxxx"
}

variable "aws_secret_key" {
    description = "AWS Secret Key"
    default     = "xxxxxx"
}

variable "aws_account_id" {
    description = "AWS Account ID"
    default     = "xxxxxx"
}

variable "subnet_id" {
    description = "Subnet ID to use in VPC"
    default     = "subnet-51997e7a"
}

variable "vpc_security_group_ids" {
    description = "vpc_security_group_ids"
    default     = "sec"
}

variable "instance_type" {
    description = "Instance type"
    default     = "t2.xlarge"
}

variable "instance_name" {
    description = "Instance Name"
    default     = "test"
}

variable "availability_zone" {
    description = "availability_zone"
    default     = "us-east-1a"
}

variable "aws_amis" {
    default = {
        "us-east-1": "ami-49c9295f",
        "eu-west-1": "ami-49c9295f",
        "us-west-1": "ami-49c9295f",
        "us-west-2": "ami-49c9295f"
    }
}

更新

从variable "aws_amis"删除variables.tf部分后，我遇到了另一个问题：

Failed to load root config module: Error loading variables.tf: 1 error(s) occurred:
* variable[aws_access_key]: invalid key: decscription

用作查找映射的aws_amis变量看起来格式不正确。相反它应该是格式：

variable "aws_amis" {
    default = {
        us-east-1 = "ami-49c9295f"
        eu-west-1 = "ami-49c9295f"
        us-west-1 = "ami-49c9295f"
        us-west-2 = "ami-49c9295f"
    }
}

作为旁边Terraform默认会查找terraform.tfvars文件，因此您可以删除-var-file="terraform.tfvars"。如果要使用不同名称的文件（例如-var-file），则需要传递prod.tfvars选项，但为此您可以省略它。

如何在.tf文件中使用带有环境变量的terraform
