我在Debezium connect producer上收到错误，但不确定我在哪里犯了错误或遗漏了什么。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？

错误是说它无法连接到 Kafka。
以下内容不应https://应用于它们

事实上，甚至不确定最后两个是有效的配置。
您可能还希望删除REQUEST_TIMEOUT_MS和RETRY_BACKOFF_MS配置，除非您有特定的用例来设置这些配置
AFAIK，不需要CONFIG_PROVIDERS_FILE_CLASS，因为文件是默认实现。
提示：使用.env文件来减少 YAML 中所需的变量数量
我们不得不增加消费者的超时，这有助于解决这个问题。ConsumerConfig.REQUEST_TIMEOUT_MS_CONFIG将其增加到60000.
此变量是org.apache.kafka.clients.consumer.ConsumerConfig的属性
