1. 下载最新的 opentelemetry-javaagent.jar from Releases

2. 运行jar

   java -javaagent:path/to/opentelemetry-javaagent.jar -jar myapp.jar
   

3. 配置 jaeger 服务

   # 方式一：
   java -javaagent:path/to/opentelemetry-javaagent.jar \-Dotel.service.name=your-service-name \-Dotel.traces.exporter=jaeger \-Dotel.exporter.jaeger.endpoint=http://localhost:14250  \-jar myapp.jar# 方式二（容器添加环境变量）：
   OTEL_TRACES_EXPORTER=jaeger
   OTEL_EXPORTER_JAEGER_ENDPOINT=http://localhost:14250
   OTEL_SERVICE_NAME=your-service-name
   

参考Dockerfile

FROM dggecr01.huawei.com:80/scan-engine/ringcentral/jdk:latest
WORKDIR /app
EXPOSE 8090
COPY ./target/myapp.jar .
COPY ./lib/opentelemetry-javaagent.jar .
CMD java -javaagent:opentelemetry-javaagent.jar -jar myapp.jar

部署jaeger，一体1.38版本

docker run -d --name jaeger   -e COLLECTOR_ZIPKIN_HOST_PORT=:9411   -e COLLECTOR_OTLP_ENABLED=true   -p 6831:6831/udp   -p 6832:6832/udp   -p 5778:5778   -p 16686:16686   -p 4317:4317   -p 4318:4318   -p 14250:14250   -p 14268:14268   -p 14269:14269   -p 9411:9411   jaegertracing/all-in-one:1.38

因为下载的是上面的opentelemetry-javaagent.jar，目前没有用到1.38版的agent，可以单独下载
