我一直在使用spotify提供的Kafka图像在本地运行Kafka。我现在正试着用它 cp-kafka-rest 以及 schema-registry 图像。
我需要帮助解决此问题：
错误（日志组： kafka_rest_1_609fd108dcf4 )
主发送线程]warn org.apache.zookeeper.clientcnxn-服务器的会话0x0zookeeper:2181，意外错误，正在关闭套接字连接并尝试重新连接

您需要将zookeeper服务添加到docker compose文件中

zookeeper:
image: confluent/zookeeper
ports:
  - "2181:2181"
environment:
  zk_id: "1"
network_mode: "host"

你没有 zookepeer 容器-它实际上是你的“ kafka “包括zookeeper和kafka服务器的服务映像，因此 zookeeper:2181 应该是 kafka:2181 但是，我建议不要使用spotify图像，因为它们已经过时了
您可以在github上找到一个功能齐全的docker compose示例，它是整个confluent5.1.0平台的一部分
这是您正在寻找的Revevant配置
