我不确定这里还缺少什么，但是我的应用程序启动失败：

我的app.yaml是

runtime: java11
manual_scaling:
  instances: 1
beta_settings:
  cloud_sql_instances: recruiters-wtf:europe-west2:recruiters-wtf=tcp:5432

我的application.properties包含：

spring.datasource.url=jdbc:postgresql://172.17.0.1:5432/${DB_NAME:recruiters_wtf}
spring.datasource.username=${DB_USER}
spring.datasource.password=${DB_PASS}

我还想念什么？该数据库已被同一应用程序的Kubernetes部署成功使用。

按照kurtisvg的回答，我将连接字符串更改为：

spring.datasource.url=jdbc:postgresql://google/recruiters_wtf?cloudSqlInstance=recruiters-wtf:europe-west2:recruiters-wtf=tcp:5432&socketFactory=com.google.cloud.sql.postgres.SocketFactory&user=${DB_USER}&password=${DB_PASS}

我已经安装了postgres-socket-factory。将错误更改为：

4 个答案:

答案 0 :(得分：5)

根据here的记录：

  

App Engine标准环境不支持连接到云   使用TCP的SQL实例。您的代码不应尝试访问   实例使用IP地址（例如127.0.0.1或172.17.0.1），除非   您已经配置了无服务器VPC访问。

首先，由于以下原因，您需要删除beta_settings文件中的app.yaml条目：

  • 它旨在用于App Engine Flexible（并实际上指示平台启动运行CloudSQL代理的Sidecar容器，而Socket Factory for JDBC则不需要此容器）
  • 您与=tcp:5432一起使用的语法实际上会指示CloudSQL代理通过TCP端口进行连接。

因此您的基本JDBC网址应类似于jdbc:postgresql://google/recruiters_wtf

您的完整数据源url为（请注意已删除的=tcp:5432部分）：

jdbc:postgresql://google/recruiters_wtf?cloudSqlInstance=recruiters-wtf:europe-west2:recruiters-wtf&socketFactory=com.google.cloud.sql.postgres.SocketFactory&user=${DB_USER}&password=${DB_PASS}

最后，请注意，正如我在上面提供的链接中所述：

  

PostgreSQL标准要求Unix套接字具有一个   套接字路径中的.s.PGSQL.5432后缀。一些图书馆使用这个   自动后缀，但其他要求您指定套接字   路径如下：/cloudsql/INSTANCE_CONNECTION_NAME/.s.PGSQL.5432。

答案 1 :(得分：0)

我看到您正在使用DB_NAME：recruiters_wtf，应该不是DB_NAME吗？

尝试使用：spring.cloud.gcp.sql.database-name（如果没有）。

还请确保使用beta

进行部署

让我知道。

答案 2 :(得分：0)

很可能发生以下两种情况之一，从而使您的k8s集群可以连接： 1.您正在使用专用IP 2.您正在使用公共IP，并将您的k8s集群添加到白名单中

如果您使用私有IP进行连接，则必须configure Serverless VPC Access才能允许App Engine连接。

如果您使用的是公共IP，您将无法将App Engine添加到白名单，因为无法保证其连接的IP。相反，我建议使用Cloud SQL JDBC Socket Factory来验证您的连接。

答案 3 :(得分：0)

确保您的服务的服务帐户具有以下IAM角色之一：

Cloud SQL Client (preferred) Cloud SQL Editor Cloud SQL Admin Or, you can manually assign the following IAM permissions:

cloudsql.instances.connect cloudsql.instances.get
