Mastering Distributed Tracing

Meet the HotROD

HotROD is a mock-up "ride-sharing" application (ROD stands for Rides on Demand) that is maintained by the Jaeger project. We will discuss its architecture later, but first let's try to run it. If you are using Docker, you can run it with this command:

$ docker run --rm -it \
    --link jaeger \
    -p8080-8083:8080-8083 \
    jaegertracing/example-hotrod:1.6 \

• The rm flag instructs Docker to automatically remove the container once the program exits.
• The it flags attach the container's standard in and out streams to the terminal.
• The link flag tells Docker to make the hostname jaeger available inside the container's networking namespace and ...
