Terraform AWS Provider 설정 방법 (Profile 기반)

Terraform AWS Provider 설정 방법 (Profile 기반)

Terraform에서 AWS 리소스를 생성하기 위해서는 AWS Credential + Provider 설정이 필요합니다.

1. AWS Credential 설정

credentials 파일

vim ~/.aws/credentials

[terraformA]
aws_access_key_id = AWSACCESSKEYID
aws_secret_access_key = AWSSECRETACCESSKEY

config 파일

vim ~/.aws/config

[terraformA]
region = us-east-1

중요 config 파일에서는 반드시 profile prefix 필요

2. Terraform 디렉터리 구조

mkdir -p terraformA/aws/serviceA/us-east-1
cd terraformA/aws/serviceA/us-east-1

구조 의미

• terraformA → AWS 계정/프로파일
• serviceA → 서비스 단위 (VPC, EC2 등)
• us-east-1 → 리전 분리

3. Provider 정의

aws provider

 

728x90

vim provider.tf

terraform {
  required_version = ">= 1.3.0"

  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 3.25"
    }
  }
}

provider "aws" {
  profile = "terraformA"
  region  = "us-east-1"
}

4. 초기화 (Provider 설치)

terraform init

Initializing the backend...

Initializing provider plugins...
- Reusing previous version of hashicorp/aws from the dependency lock file
- Installing hashicorp/aws v3.25.0...
- Installed hashicorp/aws v3.25.0 (signed by HashiCorp)

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

5. 설정 검증

terraform validate

6. AWS 인증 확인 (권장)

Terraform 실행 전 AWS 인증 정상 여부 확인

aws sts get-caller-identity --profile terraformA
