Zipkin 2.27.0 adds Eureka integration and adds a docker HEALTHCHECK timeout to ensure abhorrent checks take no longer than one second. Thanks a lot to @anuraaga @rogierslag and @reta for support on this release.
Eureka
Eureka is a service registry originally started at Netflix. Zipkin can register itself in Eureka, allowing traced services to discover its listen address and health state. This is enabled when EUREKA_SERVICE_URL is set to a valid v2 endpoint of the Eureka REST API.
Example usage:
$ EUREKA_SERVICE_URL=http://localhost:8761/eureka/v2 java -jar zipkin.jarNote: Eureka server registration only includes host and port details. Tracers need to resolve this to the POST endpoint "/api/v2/spans". See our server documentation for more.
Note: This setting does not cause Zipkin to use Eureka to discover any configured dependencies such as Kafka or Elasticsearch. If you need something like this, please open an issue and discuss your setup.
Other service registries
We added Eureka first first due to popular demand. If you need Consul please find or open an issue. Consul should be easy as Zipkin is an Armeria app, and Armeria already supports it. Similar situation with ZooKeeper (which was how zipkin was originally discovered at Twitter!). Nacos has been requested, but not in a long time. If interested, please 👍 the corresponding issue. We might need a hand with Nacos.
