Eureka server DNS config
ache...@gmail.com
I am trying to setup a Eureka server with DNS config and I am having trouble setting this up. Below is my config.
eureka:
datacenter: cloud
instance:
nonSecurePort: ${server.port}
client:
fetchRegistry: true
eurekaServerURLContext: eureka
region: us-east-1
eurekaServerPort: 8761
useDnsForFetchingServiceUrls: true
eurekaServerDNSName: dev.domain.com
registerWithEureka: true
server:
renewalPercentThreshold: 0.49
enableSelfPreservation: false
These are the TXT records I have configured
TXT Records
txt.us-east-1.dev.domain.com -> txt.us-east-1b.dev.domain.com; txt.us-east-1d.dev.domain.com
txt.us-east-1b.dev.domain.com -> eureka-us-east-1b.dev.domain.com
txt.us-east-1d.dev.domain.com -> eureka-us-east-1d.dev.domain.com
A-Record:
eureka-us-east-1b.dev.domain.com -> xx.xxx.xxx.xxx
eureka-us-east-1d.dev.domain.com -> xx.xxx.xxx.xxx
When I start the app the eureka UI comes up fine; however, I see the below on the logs.

I would like to know why Eureka is trying to use EIP when I am using the DNS configuration ? Also, on the UI page, the 'available replicas' row is empty and the instance shows in 'unavailable replicas'. Appreciate any clues on what I might be missing here.
Thanks.
