3.2. アカウント全体の IAM ロールおよびポリシー参照

このセクションでは、Operator ポリシーを含む、STS を使用する ROSA デプロイメントに必要なアカウント全体の IAM ロールおよびポリシーに関する詳細を提供します。また、ポリシーを定義する JSON ファイルも含まれます。

アカウント全体のロールおよびポリシーは、OpenShift マイナーリリースバージョン (OpenShift 4.15 など) に固有のものであり、後方互換性があります。パッチバージョンに関係なく、同じマイナーバージョンの複数のクラスターにアカウント全体のロールおよびポリシーを再利用することで、必要な STS リソースを最小限に抑えることができます。

3.2.1. アカウント全体のロールを作成する方法

Red Hat OpenShift Service on AWS (ROSA) CLI、rosa、または OpenShift Cluster Manager のガイド付きインストールを使用して、アカウント全体のロールを作成できます。手動で、またはこれらのロールおよびポリシーに事前定義された名前を使用する自動プロセスを使用して、ロールを作成できます。

手動 ocm-role リソースの作成

システムでこれらのロールを作成するのに必要な CLI アクセスがある場合は、手動作成方法を使用できます。このオプションは、目的の CLI ツールまたは OpenShift Cluster Manager から実行できます。手動作成プロセスを開始すると、CLI は、ロールを作成して必要なポリシーにリンクする一連のコマンドを実行するために表示します。

自動 ocm-role リソースの作成

管理者権限で ocm-role リソースを作成した場合は、OpenShift Cluster Manager からの自動作成方法を使用できます。ROSA CLI では、これらのロールとポリシーを自動的に作成するために、この管理 ocm-role IAM リソースが必要です。この方法を選択すると、デフォルト名を使用するロールおよびポリシーが作成されます。

OpenShift Cluster Manager で ROSA ガイド付きインストールを使用する場合は、ガイド付きクラスターインストールの最初のステップで、管理者権限を持つ ocm-role リソースを作成しておく必要があります。このロールがないと、Operator ロールおよびポリシーの自動作成オプションを使用できませんが、クラスターと、そのロールおよびポリシーを手動プロセスで作成することはできます。

注記

sts_installer_trust_policy.json および sts_support_trust_policy.json サンプルに存在するアカウント番号は、必要なロールを引き受けることが許可されている Red Hat アカウントを表します。

3.2.2. アカウント全体の IAM ロールおよびポリシー AWS CLI リファレンス

このセクションでは、rosa コマンドが端末で生成する aws CLI コマンドをリスト表示します。コマンドは、手動モードまたは自動モードのいずれかで実行できます。

アカウントロールの作成に手動モードを使用する

手動のロール作成モードでは、確認して実行するための aws コマンドが生成されます。このプロセスは次のコマンドで開始します。<openshift_version> は、Red Hat OpenShift Service on AWS (ROSA) のバージョン (4.15 など) を指します。

$ rosa create account-roles --mode manual
注記

提供されているコマンドの例には、ManagedOpenShift 接頭辞が含まれています。--prefix オプションを使用してカスタム接頭辞を指定しない場合は、ManagedOpenShift 接頭辞がデフォルト値です。
