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。

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。

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 AUTOSCALER_MIN_SIZE_*，則 annotations 設定採用值 WORKER_MACHINE_COUNT_*。		 在 Cluster 物件中，在 spec.topology.workers 下：
machineDeployments:

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

    noProxy: 
    - .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 (../../config-ref.md#proxies)。 
TKG_PROXY_CA_CERT: "LS0tLSBL[...]"

    - 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。
