Make Eureka peer awareness work out of the box about spring-cloud-netflix HOT 6 CLOSED

It would be nice to at least test that this works with a Spring Cloud Eureka server. You would have to run 2 of them in EC2, configure the client serviceUrls to point to each other (in application.yml), and then start registering apps. The apps would have to be running in EC2 as well, and they would need a DefaultEurekaInstanceConfig (overriding the @Bean provided by Spring Cloud) so that the DataCenterInfo is AmazonInfo.

Note that, by the dynamic nature of Eureka and its reliance on hearbeats to keep itself up to date, a single instance is good enough for a lot of use cases as long as it is restarted if it gets into trouble. To demonstrate this we could use CF elastic runtime to always have one instance of Eureka running. An interesting experiment would be to see Hystrix and Ribbon continue to try and use stale caches while Eureka is down.

I would be willing to give this a try, We use AWS and we have an internal issue for setting up a cluster for Eureka based on Spring Cloud. My assumption has been that just adding the config details as if it is a standard Eureka installation should work. It appears all that is needed is an elastic IP and a couple of Eureka instances plus the config properties.

Please do. I actually tried it myself locally and it does work (so peer awareness is not tied to AWS, but it would still be good to know it works).

I have tested it in aws and it is working. Using 1.0.0.M1 had to use the /v2 url instead of /eureka

Did not use the netflix dns version of peer discovery. Configured the instances using serviceURL. Did not try across regions.

@dsyer do you have any example repo eureka peer awareness on aws inside a vpc subnet ?
I'm getting "failed to bind EIP error".
