Kubernetes 代理可能不可用错误Kafka架构注册表

我已经使用Kubernetes部署和服务定义了Kafka和Kafka模式注册表配置。我将其用作环境变量设置的参考。但是，当我尝试使用注册表运行Kafka时，我看到模式注册表pods崩溃，日志中显示错误消息：

[kafka-admin-client-thread | adminclient-1] WARN
org.apache.kafka.clients.NetworkClient - [AdminClient
clientId=adminclient-1] Connection to node -1
(localhost/127.0.0.1:9092) could not be established. Broker may not be
available.
    [main] ERROR io.confluent.admin.utils.ClusterStatus - Error while getting broker list.
    java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.TimeoutException: Timed out waiting for
a node assignment.

这一错误的原因可能是什么

您已将Schema Registry配置为在

Kafka:9092

中查找Kafka代理，但还将Kafka代理配置为将其地址公布为

localhost:9092

我对Kubernetes不太熟悉，但介绍了在使用容器、IaaS等时原则上如何处理网络配置。

我遇到了同样的错误，我遵循了cricket_007的答案，问题得到了解决

只需将KAFKA_advised_LISTENERS值从PLAINTEXT://localhost:9092更改为PLAINTEXT://schema registry service:9092

我犯了一个错误，粘贴了我的旧版本。我当前的版本是使用localhosts的，但是，它会产生相同的错误

localhost

比

kafka

更不正确。播发的侦听器必须是其他POD可以访问Kafka的服务DNS名称。模式注册表必须使用该名称，而不是

localhost

。。。。我建议尝试使用合流舵图来简化平台的部署
