10.13. Azure でのブートストラップマシンの作成
OpenShift Container Platform クラスターの初期化を実行する際に使用するブートストラップマシンを Microsoft Azure で作成する必要があります。このマシンを作成する方法として、提供される Azure Resource Manager (ARM) テンプレートを変更することができます。
提供されている ARM テンプレートを使用してブートストラップマシンを作成しない場合、指定される情報を確認し、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
- Azure アカウントを設定します。
- クラスターの Ignition 設定ファイルを生成します。
- Azure で VNet および関連するサブネットを作成し、設定します。
- Azure でネットワークおよびロードバランサーを作成し、設定します。
- コントロールプレーンおよびコンピュートロールを作成します。
手順
-
このトピックの ブートストラップマシンの ARM 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
04_bootstrap.json
としてクラスターのインストールディレクトリーに保存します。このテンプレートは、クラスターに必要なブートストラップマシンを記述しています。 ブートストラップ URL 変数をエクスポートします。

ブートストラップ Ignition 変数をエクスポートします。

az
CLI を使用してデプロイメントを作成します。Copy to Clipboard Copied! Toggle word wrap Toggle overflow az deployment group create -g ${RESOURCE_GROUP} \ --template-file "<installation_directory>/04_bootstrap.json" \ --parameters bootstrapIgnition="${BOOTSTRAP_IGNITION}" \ --parameters baseName="${INFRA_ID}"
