6.7. 推奨されるインストール後のクラスター設定
クラスターのインストールが完了すると、ZTP パイプラインは、DU ワークロードを実行するために必要な次のカスタムリソース (CR) を適用します。
GitOps ZTP v4.10 以前では、MachineConfig
CR を使用して UEFI セキュアブートを設定します。これは、GitOps ZTP v4.11 以降では不要になりました。v4.11 では、クラスターのインストールに使用する SiteConfig
CR の spec.clusters.nodes.bootMode
フィールドを更新することで、シングルノード OpenShift クラスターの UEFI セキュアブートを設定します。詳細は、SiteConfig および GitOps ZTP を使用したマネージドクラスターのデプロイ を参照してください。
6.7.1. Operator
DU ワークロードを実行するシングルノード OpenShift クラスターには、次の Operator をインストールする必要があります。
- Local Storage Operator
- Logging Operator
- PTP Operator
- SR-IOV Network Operator
カスタム CatalogSource
CR を設定し、デフォルトの OperatorHub
設定を無効にし、インストールするクラスターからアクセスできる ImageContentSourcePolicy
ミラーレジストリーを設定する必要もあります。

CR が必要です。サブスクリプションは、次の Operator をダウンロードする場所を提供します。
- Local Storage Operator
- Logging Operator
- PTP Operator
- SR-IOV Network Operator
- SRIOV-FEC Operator
Operator サブスクリプションごとに、Operator の取得先であるチャネルを指定します。推奨チャンネルは stable
です。
Manual
更新または Automatic
更新を指定できます。Automatic
モードでは、Operator は、レジストリーで利用可能になると、チャネル内の最新バージョンに自動的に更新します。Manual
モードでは、新しい Operator バージョンは、明示的に承認された場合にのみインストールされます。
サブスクリプションには Manual
モードを使用します。これにより、スケジュールされたメンテナンス期間内に収まるように Operator の更新タイミングを制御できます。

6.7.9. Console Operator
クラスターケイパビリティー機能を使用して、コンソールオペレーターがインストールされないようにします。ノードが一元的に管理されている場合は必要ありません。Operator を削除すると、アプリケーションのワークロードに追加の領域と容量ができます。
マネージドクラスターのインストール中に Console Operator を無効にするには、SiteConfig
カスタムリソース (CR) の spec.clusters.0.installConfigOverrides
フィールドで次のように設定します。
installConfigOverrides: "{\"capabilities\":{\"baselineCapabilitySet\": \"None\" }}"
installConfigOverrides: "{\"capabilities\":{\"baselineCapabilitySet\": \"None\" }}"
6.7.10. Alertmanager
DU ワークロードを実行するシングルノード OpenShift クラスターでは、OpenShift Container Platform モニタリングコンポーネントによって消費される CPU リソースを削減する必要があります。以下の ConfigMap
カスタムリソース (CR) は Alertmanager を無効にします。
推奨されるクラスターモニタリング設定 (ReduceMonitoringFootprint.yaml
)

6.7.11. Operator Lifecycle Manager
分散ユニットワークロードを実行するシングルノード OpenShift クラスターには、CPU リソースへの一貫したアクセスが必要です。Operator Lifecycle Manager (OLM) は定期的に Operator からパフォーマンスデータを収集するため、CPU 使用率が増加します。次の ConfigMap
カスタムリソース (CR) は、OLM によるオペレーターパフォーマンスデータの収集を無効にします。
推奨されるクラスター OLM 設定 (ReduceOLMFootprint.yaml
)
apiVersion: v1 kind: ConfigMap metadata: name: collect-profiles-config namespace: openshift-operator-lifecycle-manager data: pprof-config.yaml: | disabled: True

6.7.12. LVM Storage
論理ボリュームマネージャー (LVM) ストレージを使用して、シングルノード OpenShift クラスター上にローカルストレージを動的にプロビジョニングできます。
シングルノード OpenShift の推奨ストレージソリューションは、Local Storage Operator です。LVM Storage も使用できますが、その場合は追加の CPU リソースを割り当てる必要があります。
次の YAML の例では、OpenShift Container Platform アプリケーションで使用できるようにノードのストレージを設定しています。

| LVM Storage に使用されるディスクを設定します。ディスクが指定されていない場合、LVM Storage は指定されたシンプール内のすべての未使用ディスクを使用します。 |
6.7.13. ネットワーク診断
DU ワークロードを実行するシングルノード OpenShift クラスターでは、これらの Pod によって作成される追加の負荷を軽減するために、Pod 間のネットワーク接続チェックが少なくて済みます。次のカスタムリソース (CR) は、これらのチェックを無効にします。
推奨されるネットワーク診断設定 (DisableSnoNetworkDiag.yaml
