I am trying to run a Eureka server in AWS.
I created a Springboot app annotated with @EnableEurekaServer but whenever the app started in AWS i got the following log message:
2017-03-29 04:11:39.886 INFO 19046 --- [ Thread-10] o.s.c.n.e.server.EurekaServerBootstrap : isAws returned false
Worried that I had done something wrong in my app I tried out the Eureka Spring cloud sample from https://github.com/spring-cloud-samples/eureka.git
I have the exact same problem - even though I am running on an EC2 instance, Eureka fails to detect this.
The server itself does start but it is ignoring all of my AWS specific config such as EIP binding.
Here is the full log output from running mvn clean spring-boot:run

I think if isAws was equal to true then my problems would be solved but there is no other detail with that message as to why Eureka thinks it isn't running in AWS even though it is.
I have also tried passing the parameter -Deureka.datacenter=cloud to no effect.
To test this out just spin up any ec2 instance (a t2.medium in my case), install git and maven (java8 should already be installed), checkout https://github.com/spring-cloud-samples/eureka.git, run the sprintboot app.
So I figured it out.
Out of the box, Springboot Eureka doesn't include the required dependency to work out if it's in AWS or not.
I added the following to the POM:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-aws-autoconfigure</artifactId>
<version>1.2.1.RELEASE</version>
</dependency>
Once I had done that then Eureka was able to determine it was in AWS.
Note that I think you can play with this dependency - I think all that is required is the AWS ec2 dependency com.amazonaws/aws-java-sdk-ec2 but I never tested this.
