infracost で AWS S3 のコストを計算させる
Amazon S3 object(1GB) の terraform resource
test.tf
resource "aws_s3_bucket" "example" {
bucket = "duck-tf-test-bucket"
tags = {
Name = "My bucket"
Environment = "Dev"
}
}
resource "aws_s3_bucket_object" "example" {
key = "duck-test-object"
bucket = aws_s3_bucket.example.id
source = "index.html"
}
AWS S3 object のサイズは 1GB で作成した。
infracost を実行してもコストが$0.00になる
$ infracost breakdown --path .

Amazon S3のバケットの保存容量やアクセス頻度が不明なためコストが$0.00と表示されてしまう。
解決策
次の手順で保存容量やアクセス頻度を指定すれば正しく料金が計算できる。
従量課金用の設定ファイルを作成する
infracost breakdown --sync-usage-file --usage-file infracost-usage.yml --path .
オプション
- sync-usage-file: 現在の terraform resource を参照し、従量課金用の設定ファイルのテンプレートを作成する。
- usage-file:
- これで指定した従量課金用の設定ファイルを反映したコスト計算を行う。
sync-usage-file は usage-file で指定したファイルに上書きする形で設定ファイルを作る点に注意。
両方のオプションを同時に実行すると sync-usage-file で設定ファイル上書きした後に usage-file で参照してコスト計算の順になるので、正しいコストが計算されない。
従量課金用の設定ファイルの編集
長いので折りたたみ。わかりやすいコメントがあるので、変更は容易である。
