Apache kafka Debezium Kafka连接错误-TimeoutException:获取主题元数据时超时已过期

我在Debezium connect producer上遇到一个错误，不确定我在哪里出错或遗漏了什么。下面是我的连接器和docker文件的属性。部署在VM上的docker是否可能无法将其连接到其他VM上的数据库

谢谢

错误是无法连接到卡夫卡

以下内容不应应用https://

---

• CONNECT\u BOOTSTRAP\u服务器

• CONNECT\u CONSUMER\u SSL\u ENDPOINT\u IDENTIFICATION\u算法

• CONNECT\u PRODUCER\u SSL\u ENDPOINT\u IDENTIFICATION\u算法

事实上，甚至不确定最后两个配置是否有效

---

您可能还希望删除

请求超时\u MS

和

重试\u回退\u MS

配置，除非您有设置这些配置的特定用例

---

另外，

CONFIG\u PROVIDERS\u FILE\u类

是不需要的，因为FILE是默认实现

---

提示：使用

.env

文件减少YAML中所需变量的数量

请使用

http://localhost:8083/connectors/Procura_CDC/status

output

CONNECT\u BOOTSTRAP\u服务器

在获取主题元数据时不应在其上设置

https:

超时

通常意味着连接到引导失败你的卡夫卡经纪人在哪里？它们是在同一个Docker Compose中（如果是，请用完整Docker Compose更新您的问题），还是在其他地方？此错误通常表示您错误配置了与它们的连接。我在confluent cloud上运行kafka代理，在Docker Compose上运行连接器@RobinMoffatt我可以知道如何配置CONNECT_CONSUMER_SSL_ENDPOINT_IDENTIFICATION_算法和CONNECT_PRODUCER_SSL_ENDPOINT_IDENTIFICATION_算法，因为我正在运行CC上的代理和本地的debezium connector？任何有用的东西都可能有用。ThanksSL不是强制性的，不是。但是使用融合云，它是强制的。消费者和生产者没有“端点”。。。请告诉我你在哪里找到的设置。@Raj你解决了这个问题吗？我也有同样的问题。@Simon请确保您在docker图像和kafka connect中都提到了基本的连接器值。在我的例子中，我没有在连接器中提到键和转换器值转换器。@Raj连接器不需要。它们也将在工人级别定义。如果这回答了您的问题，请接受解决方案
