步驟 2：安裝 cert-manager

本步驟說明如何下載及安裝 cert-manager，這是 Apigee Hybrid 運作所需的工具。

安裝 cert-manager

  1. 使用下列指令，從 GitHub 安裝 cert-manager 1.11.0 版。 
    kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/v1.11.0/cert-manager.yaml

    您應該會看到回應，指出已建立 cert-manager 命名空間和多個 cert-manager 資源。例如： 

    customresourcedefinition.apiextensions.k8s.io/certificaterequests.cert-manager.io configured
customresourcedefinition.apiextensions.k8s.io/certificates.cert-manager.io configured
...
mutatingwebhookconfiguration.admissionregistration.k8s.io/cert-manager-webhook configured
validatingwebhookconfiguration.admissionregistration.k8s.io/cert-manager-webhook configured
  2. 使用下列指令，確認 cert-manager 命名空間及其對應元件已成功建立：
      kubectl get all -n cert-manager -o wide

    輸出內容應如下列示例。您應該會看到 cert-manager、cert-manager-cainjector 和 cert-manager-webhook 的 Pod。
