S3バケットをread/writeするためのIAMポリシー

AWS,EC2,IAM_Policy関連,S3

前提条件

  • 同一のAWSアカウント内のEC2から、S3バケットをread/writeするためのIAMポリシーを作成します。
  • 作成したIAMポリシーは、IAMロールに割り当てます。そして、EC2にIAMロールを適用することでEC2からアクセス可能となります。
  • EC2からのアクセスは、aws cli を想定しています。

設定方法

  • 以下、IAMポリシーでS3バケット(例:s3-bucket-name)をread/writeする時のサンプルです。
  • 当初、"Resource"に"arn:aws:s3:::s3-bucket-name"のみ指定していましたが、"arn:aws:s3:::s3-bucket-name/*"の指定も必要であることが分かりました。
  • IAMポリシーの書き方は、ビジュアルエディターとJSONの両方を編集しているとコツが掴めてきます。
