See documentation for the latest supported version 3 or the latest supported version 4.3.9.17. Azure での追加のワーカーマシンの作成
Microsoft Azure でクラスターが使用するワーカーマシンを作成するには、それぞれのインスタンスを個別に起動するか、または自動スケーリンググループなどのクラスター外にある自動プロセスを実行します。OpenShift Container Platform の組み込まれたクラスタースケーリングメカニズムやマシン API を利用できます。
この例では、Azure Resource Manager (ARM) テンプレートを使用して 1 つのインスタンスを手動で起動します。追加のインスタンスは、ファイル内に 06_workers.json というタイプのリソースを追加して起動することができます。
提供される ARM テンプレートを使用してワーカーマシンを使用しない場合、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。
- ブートストラップマシンを作成します。
- コントロールプレーンマシンを作成します。
手順
-
本トピックの ワーカーマシンの 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
06_workers.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ワーカーマシンについて記述しています。 ワーカーマシンのデプロイメントで必要な以下の変数をエクスポートします。
export WORKER_IGNITION=`cat <installation_directory>/worker.ign | base64 | tr -d '\n'`
