步驟 3：設定 GKE 叢集

指定設定覆寫值

Apigee Hybrid 安裝程式會為許多設定使用預設值，但有些設定沒有預設值。您必須為這些設定提供值，如下文所述。

1. 確認您位於 hybrid-base-directory/hybrid-files 目錄。
2. 將 overrides-small.yaml 檔案從 $APIGEECTL_HOME/examples 目錄複製到 overrides 目錄：

   cp $APIGEECTL_HOME/examples/overrides-small.yaml ./overrides/overrides.yaml

   這個範例檔案提供小型混合式執行階段安裝作業的基本設定，這類設定適合用於首次安裝作業。

3. cd 至 overrides 目錄：

cd overrides

4. 開啟 overrides.yaml 並新增必要的屬性值，如下所示。以下也提供各個屬性的詳細說明：

   語法

   overrides.yaml 檔案的結構和語法如下。red, bold italics 中的值是您必須提供的屬性值：

   gcpProjectID: project-id
   k8sClusterName: cluster-name
   org: org-name
   
   envs:
     - name: environment-name  # The same name of the env you created in the UI
       hostAlias: test-host-alias
       sslCertPath: ./certs/test-cert-name.pem
       sslKeyPath: ./certs/test-key-name.key
       serviceAccountPaths:
         synchronizer: ./service-accounts/synchronizer-service-account-name.json
         udca: ./service-accounts/udca-service-account-name.json
   
   mart:
     hostAlias: mart-host-alias
     serviceAccountPath: ./service-accounts/mart-service-account-name.json
     sslCertPath: ./certs/mart-cert-name.pem
     sslKeyPath: ./certs/mart-key-name.key
   
   metrics:
     serviceAccountPath: ./service-accounts/metrics-service-account-name.json
   
   logger:
     enabled: false

   範例

   以下範例顯示已完成的覆寫檔案，其中加入了屬性值範例：

   gcpProjectID: hybrid-project
   k8sClusterName: apigee-hybrid
   org: hybrid-org
   
   envs:
     - name: test
       hostAlias: "*"
       sslCertPath: ./certs/keystore.pem
       sslKeyPath: ./certs/keystore.key
       serviceAccountPaths:
         synchronizer: ./service-accounts/hybrid-project-apigee-synchronizer.json
         udca: ./service-accounts/hybrid-project-apigee-udca.json
   
   mart:
     hostAlias: "mart.apigee-hybrid-docs.net"
     serviceAccountPath: ./service-accounts/hybrid-project-apigee-mart.json
     sslCertPath: ./certs/fullchain.pem
     sslKeyPath: ./certs/privkey.key
   
   metrics:
     serviceAccountPath: ./service-accounts/hybrid-project-apigee-metrics.json
   
   logger:
     enabled: false

5. 完成後，請儲存檔案。

下表說明您必須在覆寫檔案中提供的每個屬性值。

sslCertPath: ./certs/keystore.pem
sslKeyPath: ./certs/keystore.key

synchronizer: ./service-accounts/hybrid-project-apigee-synchronizer.json

udca: ./service-accounts/hybrid-project-apigee-udca.json

sslCertPath: ./certs/fullchain.pem
sslKeyPath: ./certs/privkey.key

serviceAccountPath: ./service-accounts/hybrid-project-apigee-metrics.json

摘要

設定檔會告訴 Kubernetes 如何將混合型元件部署至叢集。接下來，您將將這項設定套用至叢集。
