Jaeger/Opentracing 与 Kafka 和 docker compose答案

【问题标题】：Jaeger/Opentracing with Kafka and docker composeJaeger/Opentracing 与 Kafka 和 docker compose
【发布时间】：2020-10-16 14:51:51
【问题描述】：

我只能找到将 opentracing/jaeger 与 Kafka 一起使用的旧且不完整的示例。我想在本地运行一个示例作为概念证明 - opentracing 跨越到 kafka。

我设法让其中的一些工作正常进行，但在 jeager-query 服务上我不断得到：

"msg":"Failed to init storage factory","error":"kafka: client has run out of available brokers to talk to (Is your cluster reachable?)"

我不确定是否需要使用某种存储，例如 cassandra？

【问题讨论】：

标签： apache-kafka jaeger opentracing

【解决方案1】：

可以看到jaeger-query的配置包括：SPAN_STORAGE_TYPE: "kafka"

该错误表示jaeger-query用来在Kafka中存储span的kafka客户端实际上无法到达Kafka，因此jaeger存储工厂无法初始化。

这可能是因为 Kafka 无法启动（您检查过）吗？或者你的 docker 中的网络配置错误。

【讨论】：

您好，感谢您的回答。是的，kafka 容器运行良好，我仔细检查了一遍。它很奇怪，收集器和代理工作正常，但摄取和查询都失败
