在 Kubernetes 上设置 Rundeck - 无法连接到 Postgres 数据库

Question

我是 Kubernetes 的新手，正在尝试在其上设置 Rundeck (3.3.5)。图像已正确安装。但是，当我在 AWS RDS 上添加 Postrges 数据库时，它无法连接到它。不过，我可以使用与 DBeaver 相同的 URL 和端口号连接到数据库。以下是错误和 yaml 的详细信息。非常感谢这方面的任何帮助。

错误：

问题

jdbc:postgres url 不正确。

解决方案

正如提到的和@MegaDrive68k 在评论中提到的那样，您应该使用 jdbc:postgresql 而不是 jdbc:postgres。

关于那个有 rundeck documentation。
