Cloud SQL代理和权限不足

我正在尝试在Google的Container Engine（GKE）上部署我的Spring Boot / JHipster应用程序 . 我已经找到了大部分内容，但我的数据库实例（使用Google SQL Proxy在Google Cloud SQL上运行的PostgreSQL实例）存在问题 .

我按照说明here和here来设置我的应用程序 .

• I 've set up my PostreSQL instance in cloud, and created my app' s数据库和用户 .

• 我've created an SQL service with Cloud SQL Client role -- I grabbed the JSON key, and used it to create my cloudsql-instance-credentials. I' ve还创建了我的cloudsql-db-credentials .

• 我've added the additional bits to my deployment yaml file. I' ve基本上从this GitHub sample克隆了yaml文件，并用我自己的Docker图像（托管在Google容器注册表中）替换了所有对wordpress的引用 . 我也更新了代理块，如下所示：

deployment.yaml片段：

- image: gcr.io/cloudsql-docker/gce-proxy:1.09
      name: cloudsql-proxy
          command: ["/cloud_sql_proxy", "--dir=/cloudsql",
                    "-instances=[my-project]:us-central1:[my-sql-instance-id]=tcp:5432",
                    "-credential_file=/secrets/cloudsql/credentials.json"]

最后，我更新了我的Spring Boot配置yaml文件，如下所示：

datasource:
    type: com.zaxxer.hikari.HikariDataSource
    url: jdbc:postgresql://google/[my-database]?socketFactory=com.google.cloud.sql.postgres.SocketFactory&socketFactoryArg=[my-project]:us-central1:[my-sql-instance-id]
    username: ${DB_USER}
    password: ${DB_PASSWORD}

当我部署我的部署时，图像会部署，但无法启动应用程序 . 这是我日志中的重要部分：

这个“权限不足”错误在StackOverflow上弹出很多，但我没有找到与我的情况完全相同的问题 . 这似乎是一个通用的OAuth级错误 . 我觉得我已经多次检查了我的设置与指示，我不知道在哪里可以寻找任何额外的线索 .

有任何想法吗？

Update:

感谢Vadim的指针，我已经设法超越了“权限不足”问题 . 遗憾的是，我的应用程序在启动时仍然失败，当它尝试 Build 与数据库的连接时（特别是，当Liquibase尝试开始连接到数据库以运行迁移脚本时） .

我的新错误是在驱动程序的套接字级别：
