組態檔到叢集類別變數轉換

本主題說明工作負載叢集組態檔中的變數如何轉換為基於類的 Cluster 物件及其 ClusterBootstrap 以及 Tanzu Kubernetes Grid (TKG) 中的其他從屬物件中的變數設定。如需範例 Cluster 物件及其從屬物件，請參閱以下的範例 Cluster 物件及其從屬物件。

概觀：組態檔和叢集類別變數

組態檔變數和以類別為基礎的叢集變數不同：

  • 組態檔變數包括：

  • 以類別為基礎的叢集變數設定是 Cluster 或 ClusterBootstrap 物件規格中的巢狀 YAML 設定：

    • Cluster 物件設定包括：

      • 大多數可用的叢集設定，並且可以任意更改。
      • 由 ClusterClass 物件集定義為叢集的 spec.topology.class 值。
      • 在 spec.topology 之下於 controlPlane、workers 或 variables 區塊中設定。

      • 範例設定：

        variables:
- name: imageRepository
  value:
    host: stg-project.vmware.com
    • ClusterBootstrap 設定是容器網路和其他低階基礎架構的一些一次性設定，無法在現有叢集中進行更改。

使用叢集組態檔執行 tanzu cluster create 命令 (如建立以類別為基礎的叢集中所述) 時，Tanzu CLI 執行此轉換。

節點組態

下表所列的變數用於設定控制平面和 worker 節點，以及節點執行個體執行的作業系統。有關組態檔變數欄中變數的資訊，請參閱〈組態檔變數參考〉中的節點組態。

在以類別為基礎的叢集物件欄，所有 name / value 組設定位在 spec.topology.variables 之下的 Cluster 物件定義。此欄中的範例程式碼適用於 vSphere 上的 Cluster 個物件；AWS 和 Azure 上的物件結構可能會有所不同。

 CUSTOM_TDNF_REPOSITORY_CERTIFICATE: “YPdeNjLW[…]”
 
 - name: customTDNFRepository value: certificate: YPdeNjLW[…]

Cluster Autoscaler

ENABLE_AUTOSCALER 為 true 時，Tanzu CLI 將為 Cluster Autoscaler 建立一個 Deployment 物件，並將 Cluster Autoscaler annotations 新增到 Cluster 物件。有關下方組態檔變數欄中變數的資訊，請參閱〈組態檔變數參考〉中的 Cluster Autoscaler。

組態檔變數 以類別為基礎的叢集和 Autoscaler 部署物件結構 
 AUTOSCALER_SCALE_DOWN_DELAY_AFTER_ADD: 10m AUTOSCALER_SCALE_DOWN_DELAY_AFTER_DELETE: 10s AUTOSCALER_SCALE_DOWN_DELAY_AFTER_FAILURE: 3m AUTOSCALER_SCALE_DOWN_UNNEEDED_TIME: 10m AUTOSCALER_MAX_NODE_PROVISION_TIME: 15m AUTOSCALER_MAX_NODES_TOTAL: 0
在 Cluster Autoscaler Deployment 物件中：
 spec: containers: - args: … - –scale-down-delay-after-add=10m - –scale-down-delay-after-delete=10s - –scale-down-delay-after-failure=3m - –scale-down-unneeded-time=10m - –max-node-provision-time=15m - –max-nodes-total=0
 
 AUTOSCALER_MAX_SIZE_0: 12 AUTOSCALER_MIN_SIZE_0: 8 AUTOSCALER_MAX_SIZE_1: 10 AUTOSCALER_MIN_SIZE_1: 6 AUTOSCALER_MAX_SIZE_2: 8 AUTOSCALER_MIN_SIZE_2: 4
如果未設定 AUTOSCALER_MAX_SIZE_ 或 ，則 annotations 設定採用 WORKER_MACHINE_COUNT_* 值。		 在 Cluster 物件中，在 spec.topology.workers 下：
 machineDeployments: - class: tkg-worker metadata: annotations: cluster.x-k8s.io/cluster-api-autoscaler-node-group-max-size: “12” cluster.x-k8s.io/cluster-api-autoscaler-node-group-min-size: “8” … name: md-0 - class: tkg-worker metadata: annotations: cluster.x-k8s.io/cluster-api-autoscaler-node-group-max-size: “10” cluster.x-k8s.io/cluster-api-autoscaler-node-group-min-size: “6” … name: md-1 …

Proxy 和私人映像登錄

本節列出了使用 Proxy 和私人映像登錄的變數，例如，在網際網路受限部署中。

在以類別為基礎的叢集物件欄，所有 name / value 組設定位在 spec.topology.variables 之下的 Cluster 物件定義。

組態檔變數 以類別為基礎的叢集物件結構 附註 
 TKG_CUSTOM_IMAGE_REPOSITORY: example.com/yourproject TKG_CUSTOM_IMAGE_REPOSITORY_SKIP_TLS_VERIFY: true
 
 - name: imageRepository value: host: example.com/yourproject tlsCertificateValidation: enabled: false
 tldCertificateValidation.enabled 會反轉TKG_CUSTOM_IMAGE_REPOSITORY_SKIP_TLS_VERIFY 的布林值設定，如果其值為 true，則不會寫入該設定。 
 TKG_HTTP_PROXY_ENABLED: true TKG_HTTP_PROXY: http://proxy.example.com:80 TKG_HTTPS_PROXY: https://proxy.example.com:3128 TKG_NO_PROXY: .noproxy.example.com,noproxy.example.com,192.168.0.0/24

 在內部，Tanzu CLI 會將未在組態檔中設定的值附加到 noProxy 列表值，如 [Proxy Configuration] 中所述。 
 TKG_PROXY_CA_CERT: “LS0tLSBL[…]” TKG_CUSTOM_IMAGE_REPOSITORY_CA_CERTIFICATE: “MIIEpgIH[…]"
 
 - name: trust value: - name: proxy data: LS0tLSBL[…] - name: imageRepository data: MIIEpgIH[…]
 值是 base64 編碼的 CA 憑證。
TKG_PROXY_CA_CERT 優先於 TKG_CUSTOM_IMAGE_REPOSITORY_CA_CERTIFICATE，如果設定了trust imageRespository 值，則不會寫入 trust proxy 值。		 
 ADDITIONAL_IMAGE_REGISTRY_1: “example.com/otherregistry-1” ADDITIONAL_IMAGE_REGISTRY_1_SKIP_TLS_VERIFY: false ADDITIONAL_IMAGE_REGISTRY_1_CA_CERTIFICATE: “LS0tLSBL[…]” ADDITIONAL_IMAGE_REGISTRY_2: “example.com/otherregistry-2” ADDITIONAL_IMAGE_REGISTRY_2_SKIP_TLS_VERIFY: true ADDITIONAL_IMAGE_REGISTRY_3: “example.com/otherregistry-3” ADDITIONAL_IMAGE_REGISTRY_3_SKIP_TLS_VERIFY: false ADDITIONAL_IMAGE_REGISTRY_3_CA_CERTIFICATE: “MIIEpgIH[…]”
