Question

我试图将我的spring应用程序连接到debezium / kafka：0.10，但是没有成功。最初，该应用程序使用wurstmeister / kafka图像，但是现在，我要为debezium引入一项新功能，并且希望仅对其中一个使用kafka图像。我无法将两个应用程序都连接到debezium kafka或将debezium连接到wurstmeister kafka。有人知道这两种图像只能使用一张吗？任何想法都欢迎：）

问题是该应用无法将主题创建到debezium容器中。而且debezium无法使用wurstmeister kafka图像。

Answer 1

与 ADVERTISED_HOST_NAME 一起，您需要向容器环境中添加 ADVERTISED_LISTENERS 。

ADVERTISED_LISTENERS-经纪人将在Zookeeper中注册此值，并且当外部世界想要连接到您的Kafka群集时，他们可以通过您在ADVERTISED_LISTENERS属性中提供的网络进行连接。

示例：

import speech_recognition as sr

rec = sr.Recognizer()

print('say something')
with sr.Microphone() as source:
    audio = rec.listen(source)
    voice_data = rec.recognize_google(audio)

print(voice_data)

无法将Spring应用程序连接到Debezium Kafka
