java - 无法使用spring-boot应用程序从Jaeger UI追踪服务。
无法在Jaeger UI(localhost:16686search)上追踪springboot应用的服务。在这里,我可以成功运行一个应用程序,但无法在jaeger ui中获得服务(除了defalut一个jaeger-query)。
我使用docker cmd来启动jaeger服务。
docker run --rm -it --network=host jaegertracing/all-in-one
打开积家的用户界面 http:/localhost:16686search

Github 仓库,有演示。https:/github.compavolloffayopentracing-java-examples。请帮我解决这个问题。
【回答】:
问题是你的Jaeger收集器不能像你在docker命令中指定的那样从docker网络主机外部访问。只有当你的spring boot应用程序部署在主机网络上时,这才会有效。
docker run -d --name jaeger \
-e COLLECTOR_ZIPKIN_HTTP_PORT=9411 \
-p 5775:5775/udp \
-p 6831:6831/udp \
-p 6832:6832/udp \
-p 5778:5778 \
-p 16686:16686 \
-p 14268:14268 \
-p 14250:14250 \
-p 9411:9411 \
jaegertracing/all-in-one:1.17
它应该会触发。
