在 docker-compose 中设置 Jaeger - 不使用一体化映像

Question

我想要 docker-compose 文件中的解决方案。我拿了这个 docker-compose 文件和这个 one。

我提出了以下建议，但与 Jaeger 收集器通信的服务存在问题。

你没有将 4317 映射到我能看到的任何地方（添加 -p 4317:4317）。此外，您还必须在收集器上启用 OLTP -e COLLECTOR_OTLP_ENABLED=true。在 service-a 和 service-b 定义中添加 jaeger-collector 的 dependent_on 条目，这将确保收集器首先出现。

为什么不使用其他东西来管理 Kafka，而只是在容器中这样做？没有任何冗余的 Kafka 并不是最好的主意。
