將 Kubernetes 元件新增到 Cloud Assembly 雲端範本時，您可以選擇新增叢集或讓使用者能夠在各種組態中建立命名空間。此選項通常取決於存取控制需求、設定 Kubernetes 元件的方式以及部署需求。
若要在 Cloud Assembly 中將 Kubernetes 元件新增至雲端範本，請選取，按一下新增，然後找到並展開左側功能表上的 Kubernetes 選項。然後，透過將所需選項 (叢集或 KBS 命名空間) 拖曳至畫布來進行選取。
將與專案相關聯的 Kubernetes 叢集新增至雲端範本，是使 Kubernetes 資源可供有效使用者使用的最簡單方法。您可以在叢集上使用標籤來控制其部署位置，如同處理其他 Cloud Assembly 資源一樣。在叢集部署的配置階段，可以使用標籤來選取區域和 VMware Tanzu Kubernetes Grid Integrated Edition (TKGI) 計劃。
一旦以這種方式新增叢集，該叢集就會自動可供所有有效的使用者使用。
雲端範本範例
第一個雲端範本範例會顯示透過標記來控制的簡單 Kubernetes 部署的範本。Kubernetes 區域是使用在 [新增 Kubernetes 區域] 頁面上設定的兩個部署計劃建立的。在此案例中，名為 placement:tag 的標籤已新增為區域上的一項功能，用於比對雲端範本上的類似限制。如果有多個區域設定了此標籤，則會選取具有最低優先順序編號的區域。
formatVersion: 1
inputs: {}
resources:
Cluster_provisioned_from_tag:
type: Cloud.K8S.Cluster
properties:
hostname: 109.129.209.125
constraints:
-tag: 'placement tag'
port: 7003
workers: 1
connectBy: hostname
第二個雲端範本範例顯示如何使用名為 $(input.hostname) 的變數設定範本，以便使用者能夠在請求部署時輸入所需的叢集主機名稱。在叢集部署的資源配置階段，也可以使用標籤來選取區域和 TKGI 計劃。
formatVersion: 1
inputs:
hostname:
type: string
title: Cluster hostname
resources:
Cloud_K8S_Cluster_1:
type: Cloud.K8S.Cluster
properties:
hostname: ${input.hostname}
port: 8443
connectBy: hostname
workers: 1
如果您想要使用命名空間來管理叢集使用率，您可以在名為 name: ${input.name} 的雲端範本中設定一個變數，以取代請求部署時使用者輸入的命名空間名稱。對於此類部署，您需要建立一個如以下範例所示的範本：
1 formatVersion: 1
2 inputs:
3 name:
4 type: string
5 title: "Namespace name"
6 resources:
7 Cloud_KBS_Namespace_1:
8 type: Cloud.KBS.Namespace
9 properties:
10 name: ${input.name}
使用者可以透過 kubeconfig 檔案來管理已部署的叢集，這些檔案可從頁面存取。在頁面上找到所需叢集對應的卡，然後按一下 Kubeconfig。
VMware Cloud Templates 中的主管命名空間

VMware Cloud Templates 支援對主管命名空間使用限制。限制可讓您控制 CPU 和記憶體的資源使用率，以及已部署機器允許在命名空間中使用的網繭數目上限。
