Red Hat Summit7.4. HCI Compute ノード用のカスタム NIC heat テンプレート
以下は、HCI Compute ノードの NIC 設定が含まれる heat テンプレート例です。heat テンプレートの設定は、ネットワークを次のブリッジとインターフェイスにマッピングします。
| Networks | ブリッジ | インターフェイス |
|---|---|---|
| コントロールプレーン、ストレージ、内部 API | 該当なし |
|
| 外部、テナント |
|
|
デプロイメントで次のテンプレートを使用するには、この例をワークステーションの custom_templates ディレクトリーの multiple_nics_vlans_dvr.j2 にコピーします。ベアメタルノードの NIC 設定に合わせてこの設定を変更できます。
