This repo contains linkerd telemeters for writing tracing data to Zipkin, using linkerd's plugin interface and Zipkin's finagle-zipkin library.

To build a plugin jar, run:

$ ./sbt assembly

That will build a linkerd-zipkin plugin jar in plugins/. Put that jar in linkerd's class path to make the telemeters available. Further information on installing plugins is available in the linkerd plugin documentation.

If you're using Docker, this repo provides a Dockerfile that you can use to layer in the plugin jar on top of the linkerd base image. To build, run:

$ ./sbt assembly
$ docker build -t linkerd-zipkin:latest .

That will build a docker image called linkerd-zipkin:latest, which runs linkerd and autoloads the telemeters from this repo. You can tag that image as needed and push to your own docker repo for deployment.

Two telemeters are provided, for writing to Zipkin with different transports.
