S3 버킷 및 IAM 관리

S3 및 Terraform: 클라우드 스토리지

첫 번째 S3 버킷

resource "aws_s3_bucket" "my_unique_bucket" {
  bucket = "my-coddykit-unique-bucket-12345" # Replace with a globally unique name
}

output "bucket_id" {
  value = aws_s3_bucket.my_unique_bucket.id
}

버킷 이름 지정 및 리전

S3 보안 및 기능

resource "aws_s3_bucket" "my_versioned_bucket" {
  bucket = "coddykit-versioned-bucket-98765" # Replace with a unique name
}

resource "aws_s3_bucket_versioning" "my_versioned_bucket_versioning" {
  bucket = aws_s3_bucket.my_versioned_bucket.id
  versioning_configuration {
    status = "Enabled"
  }
}

resource "aws_s3_bucket_public_access_block" "my_versioned_bucket_public_access_block" {
  bucket = aws_s3_bucket.my_versioned_bucket.id

  block_public_acls       = true
  block_public_and_cross_account_access = true
  ignore_public_acls      = true
  restrict_public_buckets = true
}

output "bucket_name_versioned" {
  value = aws_s3_bucket.my_versioned_bucket.bucket
}

AWS IAM: 자격 증명 및 액세스

IAM 사용자 프로비저닝

resource "aws_iam_user" "coddykit_user" {
  name = "coddykit-app-user"
  path = "/system/"
  tags = {
    Department = "DevOps"
  }
}

output "iam_user_name" {
  value = aws_iam_user.coddykit_user.name
}

output "iam_user_arn" {
  value = aws_iam_user.coddykit_user.arn
}

IAM 정책 이해하기

S3 권한 부여

resource "aws_s3_bucket" "policy_target_bucket" {
  bucket = "coddykit-policy-bucket-112233" # Unique name
}

resource "aws_iam_user" "s3_reader_user" {
  name = "coddykit-s3-reader"
}

data "aws_iam_policy_document" "s3_read_only_policy" {
  statement {
    actions = [
      "s3:GetObject",
      "s3:ListBucket"
    ]
    resources = [
      aws_s3_bucket.policy_target_bucket.arn,
      "${aws_s3_bucket.policy_target_bucket.arn}/*"
    ]
  }
}

resource "aws_iam_policy" "s3_read_only" {
  name        = "CoddyKitS3ReadOnlyPolicy"
  description = "Grants read-only access to a specific S3 bucket"
  policy      = data.aws_iam_policy_document.s3_read_only_policy.json
}

resource "aws_iam_user_policy_attachment" "attach_s3_read_only" {
  user       = aws_iam_user.s3_reader_user.name
  policy_arn = aws_iam_policy.s3_read_only.arn
}

output "s3_reader_user_name" {
  value = aws_iam_user.s3_reader_user.name
}

output "s3_read_only_policy_arn" {
  value = aws_iam_policy.s3_read_only.arn
}
