This is the documentation for the default architecture of Red Hat OpenShift Service on AWS. The classic architecture documentation is available here.
1.6. Operator のロールとポリシーの作成
Red Hat OpenShift Service on AWS クラスターをデプロイする際には、Operator IAM ロールを作成する必要があります。クラスター Operator は、Operator のロールとポリシーを使用して、バックエンドストレージの管理やクラスターへの外部アクセスなどのクラスター操作を実行するために必要な一時的な権限を取得します。
前提条件
Red Hat OpenShift Service on AWS の AWS 前提条件を満たしている。
インストールホストに最新の ROSA コマンドラインインターフェイス (CLI) (rosa) をインストールして設定した。
アカウント全体の AWS ロールを作成した。
手順
Operator ロールを作成するには、次のコマンドを実行します。
rosa create operator-roles --hosted-cp --prefix=$OPERATOR_ROLES_PREFIX --oidc-config-id=$OIDC_ID --installer-role-arn arn:aws:iam::$AWS_ACCOUNT_ID:role/${ACCOUNT_ROLES_PREFIX}-HCP-ROSA-Installer-Role
この値は、Red Hat OpenShift Service on AWS クラスター用に作成した OIDC 設定 ID です。
--installer-role-arn
この値は、Red Hat OpenShift Service on AWS アカウントロールの作成時に作成したインストーラーロールの ARN です。
Red Hat OpenShift Service on AWS クラスター用の正しいロールを作成するには、--hosted-cp パラメーターを含める必要があります。このコマンドは次の情報を返します。
以下に例を示します。

ここでは、以下のようになります。
Operator roles prefix
このフィールドには、最初の作成コマンドで設定した接頭辞が事前に入力されます。
OIDC 設定 ID
このフィールドでは、Red Hat OpenShift Service on AWS クラスター用に作成した OIDC 設定を選択する必要があります。
これで、Operator ロールが作成され、Red Hat OpenShift Service on AWS クラスターの作成に使用できるようになりました。
検証
Red Hat OpenShift Service on AWS アカウントに関連付けられている Operator ロールをリスト表示できます。以下のコマンドを実行します。
rosa list operator-roles
$rosa list operator-roles
