Alibaba Cloud Service Mesh：準備工作

前提條件

• 已建立ASM企業版執行個體。具體操作，請參見建立ASM執行個體。

  在建立服務網格頁面配置資料面模式時，無需選中啟用Ambient Mesh模式。

• 已建立Kubernetes叢集。具體操作，請參見建立ACK專有叢集或建立ACK託管叢集。

• 已添加叢集到ASM執行個體。具體操作，請參見添加叢集到ASM執行個體。

• 已為default命名空間啟用Sidecar網格代理自動注入。具體操作，請參見啟用自動注入。

操作步驟

請結合實際情境，按需在資料面叢集中部署helloworld、sleep、httpbin或nginx服務。
