第 4 步：配置集群

指定配置替换

Apigee Hybrid 安装程序使用许多设置的默认值；但是，有几项设置没有默认值。如下文所述，您必须为这些设置提供值。

1. 确保您位于 hybrid-base-directory/hybrid-files/overrides/ 目录中。

   cd hybrid-base-directory/hybrid-files/overrides

2. 在您首选的文本编辑器中创建名为 overrides.yaml 的新文件。例如：

   vi overrides.yaml

   overrides.yaml 提供您独特的 Apigee Hybrid 安装的配置。此步骤中的替换文件为小规模 Hybrid 运行时安装提供基本配置，适合首次安装。

3. 在 overrides.yaml 中，添加所需属性值，如下所示。下面还提供每个属性的详细说明：

   语法

   请确保 overrides.yaml 文件具有以下结构和语法。red, bold italics 中的值是您必须提供的属性值。下表中介绍了它们。

   
   gcp:
     region: analytics-region
     projectID: gcp-project-id
   
   k8sCluster:
     name: cluster-name
     region: analytics-region
   
   org: org-name
   
   instanceID: "unique-instance-identifier"
   
   cassandra:
     hostNetwork: false #Set this to `true` for GKE-On-prem installations.
   
   virtualhosts:
     - name: environment-group-name
       sslCertPath: ./certs/cert-name.pem
       sslKeyPath: ./certs/key-name.key
   
   envs:
     - name: environment-name
       serviceAccountPaths:
         synchronizer: ./service-accounts/synchronizer-service-account-name.json
         udca: ./service-accounts/udca-service-account-name.json
   
   mart:
     serviceAccountPath: ./service-accounts/mart-service-account-name.json
   
   connectAgent:
     serviceAccountPath: ./service-accounts/mart-service-account-name.json
     # Same account used for mart and connectAgent
   
   metrics:
     serviceAccountPath: ./service-accounts/metrics-service-account-name.json
   
   watcher:
     serviceAccountPath: ./service-accounts/watcher-service-account-name.json
   
   logger:
     enabled: true
     serviceAccountPath: ./service-accounts/logger-service-account-name.json
   

   示例

   以下示例展示了一个添加了示例属性值的已完成替换文件：

   gcp:
     region: us-central1
     projectID: hybrid-example
   
   k8sCluster:
     name: apigee-hybrid
     region: us-central1
   
   org: hybrid-example
   
   instanceID: "my_hybrid_example"
   
   cassandra:
     hostNetwork: false #Set this to `true` for GKE-On Prem installations.
   
   virtualhosts:
     - name: example-env-group
       sslCertPath: ./certs/keystore.pem
       sslKeyPath: ./certs/keystore.key
   
   envs:
     - name: test
       serviceAccountPaths:
         synchronizer: ./service-accounts/hybrid-project-apigee-synchronizer.json
         udca: ./service-accounts/hybrid-project-apigee-udca.json
   
   mart:
     serviceAccountPath: ./service-accounts/hybrid-project-apigee-mart.json
   
   connectAgent:
     serviceAccountPath: ./service-accounts/example-hybrid-apigee-mart.json
   
   metrics:
     serviceAccountPath: ./service-accounts/hybrid-project-apigee-metrics.json
   
   watcher:
     serviceAccountPath: ./service-accounts/hybrid-project-apigee-watcher.json
   
   logger:
     enabled: true
     serviceAccountPath: ./service-accounts/logger-service-account-name.json
   
   

4. 完成后，保存文件。

下表介绍了您必须在替换文件中提供的每个属性值。如需了解详情，请参阅配置属性参考。

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

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

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

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

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

摘要

配置文件指示 Kubernetes 如何将混合组件部署到集群。接下来，您需要将此配置应用于您的集群。
