Dears, let me talk about the issue.

1. i deployed zipkin server via docker and all server(collector、cassandra、query、web-UI) run normally ;
2. By the brave client sent log info to query service(the query default port is： 9411) ;
3. Then i can find the tracer information on the zipkin-> web-UI server 。
4. issues is：the dependencies tab have nothing to show . what should i do and then the dependencies tab will show the statistics info , thanks very much.

You must run the zipkin-dependencies-spark job. It's a single jar file that you can execute.

How do you do this when running Zipkin using the Docker image?

My 2 cents. make the dependency tab show some help information to start with.
That way, atleast people will not think it is broken.
e.g. using setup x, it will run every x min. use setup y to dun directly.
