12.12. AWS でのセキュリティーグループおよびロールの作成
OpenShift Container Platform クラスターで使用するセキュリティーグループおよびロールを Amazon Web Services (AWS) で作成する必要があります。
提供される CloudFormation テンプレートおよびカスタムパラメーターファイルを使用して、AWS リソースのスタックを作成できます。スタックは、OpenShift Container Platform クラスターに必要なセキュリティーグループおよびロールを表します。
このドキュメントの CloudFormation テンプレートを使用して AWS インフラストラクチャーを作成しない場合は、記載されている情報を確認し、インフラストラクチャーを手動で作成する必要があります。クラスターが適切に初期化されない場合、インストールログを用意して Red Hat サポートに問い合わせする必要がある可能性があります。
前提条件
- AWS アカウントを設定している。
-
aws configure
を実行して、AWS キーおよびリージョンをローカルの AWS プロファイルに追加している。 - クラスターの Ignition 設定ファイルを生成している。
- AWS で VPC および関連するサブネットを作成し、設定している。
手順
テンプレートが必要とするパラメーター値が含まれる JSON ファイルを作成します。

の形式で定義した VPC に使用した CIDR ブロックパラメーターを指定します。- 5
- VPC 用に作成したプライベートサブネット。
- 6
- VPC の CloudFormation テンプレートの出力から
PrivateSubnetIds
値を指定します。 - 7
- クラスター用に作成した VPC。
- 8
- VPC の CloudFormation テンプレートの出力から
VpcId
値を指定します。
- このトピックの セキュリティーオブジェクトの CloudFormation テンプレート セクションからテンプレートをコピーし、これをコンピューター上に YAML ファイルとして保存します。このテンプレートは、クラスターに必要なセキュリティーグループおよびロールを記述しています。
CloudFormation テンプレートを起動し、セキュリティーグループおよびロールを表す AWS リソースのスタックを作成します。
重要単一行にコマンドを入力してください。

- 提供されるテンプレートは一部の
AWS::IAM::Role
およびAWS::IAM::InstanceProfile
リソースを作成するため、CAPABILITY_NAMED_IAM
機能を明示的に宣言する必要があります。
