AWS Step Functions ステートマシンで実行されるタスクはそれぞれセッションプリンシパルが異なる

タスクが実行されるたびに AssumeRole が行われているようです。それで困ることはそうそうないと思いますが、わたしはちょっと困りました。

同じロールだけど都度 AssumeRole されている

コンバンハ、千葉(幸)です。

今回学んだことは以下です。

AWS StepFunctions ステートマシンのワークフローでは、実行する作業をタスクとして定義できます。タスクにはいくつか種別がありますが、今回は「対応した AWS サービスの API を呼び出す」タイプを想定します。

タスクとして API 実行するために必要な権限は、ステートマシンに割り当てられた IAM ロールを引き受けることで得るのが基本です。(最近のアップデートでクロスアカウントを想定してタスクごとに IAM ロールを指定できるようになりました。今回は特にこのパターンは考慮しないことにします。)

ここで、ワークフローの一連の流れで複数のタスクが実行される際、タスク間で共通した Assumed-role セッションプリンシパルを使用しているわけではありません。言い換えると、タスクごとに都度 AssumeRole しているということです。引き受ける IAM ロールは同じものであっても、セッションプリンシパルとしては別物ということです。

これを気にすべきケースはそうそうないと思いますが、たまたまわたしがやりたいことには差し支えがあったので、学びとして共有します。

今回やりたかったこと

以下の API を順に実行したかったです。

これは簡単に言えばマネジメントコンソールにおけるアクセスアドバイザーの機能を API で実行するものです。

これを AWS 管理ポリシーAdministratorAccessに対して実行することで、その時点で有効な AWS サービス(サービス名前空間基準)を確認する、ということをよくやっています。

普段は以下のような形で AWS CLI を手動で実行しているのですが、自動で定期的に実行できないかなと思い、StepFunctions の利用を検討しました。

% JOBID=$(aws iam generate-service-last-accessed-details --arn arn:aws:iam::aws:policy/AdministratorAccess --output text)
sleep 5
aws iam get-service-last-accessed-details --job-id $JOBID --max-items 1000\

ステートマシンを作って動かしてみた

以下のようなシンプルなワークフローを持つステートマシンを作ってみました。

Step_Functions_Management_Console_wsl

定義の詳細はこんな感じ。

{
  "Comment": "A description of my state machine",
  "StartAt": "GenerateServiceLastAccessedDetails",
  "States": {
    "GenerateServiceLastAccessedDetails": {
      "Type": "Task",
      "Parameters": {
        "Arn": "arn:aws:iam::aws:policy/AdministratorAccess"
      },
      "Resource": "arn:aws:states:::aws-sdk:iam:generateServiceLastAccessedDetails",
      "Next": "GetServiceLastAccessedDetails"
    },
    "GetServiceLastAccessedDetails": {
      "Type": "Task",
      "End": true,
      "Parameters": {
        "JobId.$": "$.JobId"
      },
      "Resource": "arn:aws:states:::aws-sdk:iam:getServiceLastAccessedDetails"
    }
  }
}

1 つめのタスクでジョブ ID を生成し、2 つめのタスクでそれを引数として実行する、という流れです。

これを実行してみると、2 つめのタスクでエラーが発生しました。

Step_Functions_Management_Console_execute_error

1 つめのタスクの実行結果を確認すると以下の通り。出力としてジョブ ID がきちんと生成できています。

{
  "resourceType": "aws-sdk:iam",
  "resource": "generateServiceLastAccessedDetails",
  "output": "{\"JobId\":\"d6c259b1-f4b8-d375-b411-88da4d27e630\"}",
  "outputDetails": {
    "truncated": false
  }
}

2 つめのタスクの実行結果は以下の通り。Job d6c259b1-f4b8-d375-b411-88da4d27e630 does not exist.となっています。

{
  "resourceType": "aws-sdk:iam",
  "resource": "getServiceLastAccessedDetails",
  "error": "Iam.NoSuchEntityException",
  "cause": "Job d6c259b1-f4b8-d375-b411-88da4d27e630 does not exist. (Service: Iam, Status Code: 404, Request ID: ce5ffd9d-23a5-486a-ab4b-ca3fd897f3d7)"
}

1 つめのタスクで正常に生成できているのに存在しないとは何故?となりました。

エラーの詳細を確認する

いろいろ試行錯誤した結果、これはGetServiceLastAccessedDetailsの仕様によるものだということが分かりました。

API のリファレンスを確認すると、以下の記述があります。

The JobId returned by GenerateServiceLastAccessedDetail must be used by the same role within a session, or by the same user when used to call GetServiceLastAccessedDetail.

引数として渡されるジョブ ID は、GetServiceLastAccessedDetailを実行する IAM エンティティによって生成されたものでなければならない、とあります。同じ IAM ロールを引き受けていても、セッションが異なれば別のエンティティ扱いになります。

それぞれのタスクによる API 実行を CloudTrail イベントから確認すると、以下のようになっています。

引き受けている IAM ロールはどちらもステートマシンに割り当てたStepFunctions-IAMcheck-role-e4fbfe1eですが、セッション名が異なり、別のセッションプリンシパルであることが分かります。

2 つめのタスクのセッションプリンシパルとしては自身が解釈できるジョブ ID が存在しない、ということでした。タスクを同一セッションで実行できる術があればよかったのですが、方式が思い当たらなかったので断念しました。StepFunctions 以外の方法を検討したいと思います。

終わりに

AWS StepFunctions ステートマシン内のタスクはそれぞれ別の Assumed-role セッションプリンシパルとして実行される、という話でした。

API を跨いで同一セッションであることが求められるというのはあまり聞いたことがないので、あまり意識する必要がない部分ではあると思います。ただ、タスクにはそういった仕様があることや、そういった API もある、ということを覚えておくとどこかで役に立つかもしれません。

以上、 チバユキ (@batchicchi) がお送りしました。

おまけ

残念ながら自動での定期実行の実装に至らなかったのですが、AWS CLI で手動で実行した結果を載せておきます。re:Invent の期間中にどのくらい増えるか楽しみですね。
