$ export AWS_SECRET_ACCESS_KEY=XYZ**********************************789

Terraform 配置

$ mkdir terraform-on-aws
$ cd terraform-on-aws
$ touch terraform.tf main.tf variables.tf outputs.tf

下面是一个基础的、简单的、且完整的示例：

terraform terraform.tf


terraform {
  required_version = ">= 1.3.7"

  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 4.37.0"
    }
  }
}

terraform main.tf


provider "aws" {
  region  = "ap-northeast-1"
}

resource "aws_instance" "app_server" {
  ami           = "ami-0bba69335379e17f8"
  instance_type = "t2.micro"

  tags = {
    Name = var.instance_name
  }
}

terraform variables.tf


variable "instance_name" {
  description = "Value of the Name tag for the EC2 instance"
  type        = string
  default     = "ExampleAppServerInstance"
}

terraform outputs.tf


output "instance_id" {
  description = "ID of the EC2 instance"
  value       = aws_instance.app_server.id
}

output "instance_public_ip" {
  description = "Public IP address of the EC2 instance"
  value       = aws_instance.app_server.public_ip
}
