How to Register Solr with Eureka

Question

I have 2 Spring apps ("client-app" and "service-app") that are already registered to Eureka (and talk via Feign Client). However, I have to talk to an instance of Solr and I'm forced to hard-code the IP address in the properties file. I would much rather not do this and use Eureka for service-discovery.

Question: Is there a way/plugin to have solr register itself with Eureka, so that clients can then discover it (even if it's programmatically via a start-up listener or some sort)?

I've looked at the solr API and it doesn't seem to have lifecycle listener (onStartUp or onShutdown hooks)

Answer 1

You would need a Solr Plugin for this, which is SolrCore aware. That interface method inform is called anytime something interesting happens with a core. Within the implementation of the inform method you would need to register/deregister as a client.

Then you would need to add it to your Solr (Cloud) instance. After that and proper configuration of your plugin, it should work.
