如何在.tf文件中使用terraform和環境變量

我是Terraform的新手，當嘗試在.tf文件中使用環境變量時遇到了一些問題，我嘗試使用terraform.tfvars/variables.tf。如何在.tf文件中使用terraform和環境變量

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

我在這裏錯過了什麼？

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

從variables.tf去除variable "aws_amis"節之後，我遇到了另一個問題：

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

檢查variables.tf文件行54是'availability_zone'變量的結尾括號，它沒有17個字符 - 它只是一個右括號。你在你提供的文件中丟失了什麼？ – ydaetskcoR

另外你的'aws_amis'地圖對我來說看起來不對。它應該看起來像'us-east1 =「ami-49c9295f」「等等，而不是」us-east-1「：」ami-49c9295f「，'。儘管HCL是JSON的超集，所以我總是對可以在其中使用JSON的位置感到困惑。 – ydaetskcoR

@ydaetskcoR謝謝，我現在有另一個問題，請看看問題更新。 – Berlin

的aws_amis變量被用作查找地圖看起來格式不正確我。相反，它也許應該格式：

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

順便Terraform將尋找一個terraform.tfvars文件默認情況下，這樣你就可以刪除-var-file="terraform.tfvars"。如果要使用不同名稱的文件（例如prod.tfvars），則需要通過-var-file選項，但爲此您可以忽略它。
