We are a Java shop and use Consul (as a docker container) for our service discovery. Spring Cloud Consul plays well with Consul. The REST APIs are what makes Consul stand out. We have an in-house monitoring service querying consul apis for service removals & healthy service counts and send an alert if there are no more healthy services, so that our docker can spin up one just in time.

Another feature that we use is the KV configuration dynamic reloading. So all your yml configurations are in Consul and can be updated and propagated to all of your services on the fly.

Now the problem we face is Spring Cloud Consul project is maintained by a very few people, so if there is an issue, we have to workaround than waiting for a fix.
