我正在尝试使用docker-compose运行本地kafka-connect集群。
我需要连接到远程数据库，同时还在使用远程kafka和schema-registry。
我已经允许从我的计算机访问这些远程资源。
为了启动集群，在我的Ubuntu WSL2终端中的项目文件夹中，我运行以下命令：
docker build -t my-connect:1.0.0
docker-compose up 应用程序成功运行，但是当我尝试创建新的连接器时，返回错误500并超时。 我的Dockerfile

测试与数据库的连接
$ telnet 数据库主机名 1521
正在尝试 <ip>... 已连接到数据库主机名
测试与kafka broker的连接
$ telnet broker1.intranet 9092
正在尝试 <ip>... 已连接到broker1.intranet
测试与远程schema-registry的连接
$ telnet schema-registry.intranet 8081
正在尝试 <ip>... 已连接到schema-registry.intranet
我做错了什么？我需要配置其他内容以允许连接到这个远程数据库吗？
