Postsres的K8s TLS秘密| GKE和Google Cloud SQL Postgres

我在Web服务和远程托管的Postgres数据库之间 Build SSL连接时遇到了麻烦 . 使用与Web服务相同的证书和密钥文件，我可以使用pgAdmin和DataGrip等工具连接到数据库 . 这些文件是从Google Cloud Console中的Postgres实例下载的 .

Issue:

在Spring Boot服务启动时，发生以下错误：

org.postgresql.util.PSQLException: Could not read SSL key file /tls/tls.key

在我查看Postgres服务器日志的地方，错误记录为

LOG: could not accept SSL connection: UNEXPECTED_RECORD

Setup:

在Minikube（本地）上运行的Spring Boot服务和连接到Google Cloud SQL Postgres实例的GKE .

Actions Taken:

我已经下载了客户端证书和密钥 . 我使用下载的客户端证书和密钥创建了K8s TLS Secret . 我还确保通过在k8s部署配置上运行以下命令从卷装入读取文件：

command: ["bin/sh", "-c", "cat /tls/tls.key"]

这是通过环境变量（DATASOURCE）输入的数据源URL .

"jdbc:postgresql://[Database-Address]:5432/[database]?ssl=true&sslmode=require&sslcert=/tls/tls.crt&sslkey=/tls/tls.key"

这是k8s部署yaml，任何想法我哪里出错？
