The ribbon client gets the IP-address of the pod running organization service. current list of Servers=[10.1.0.190:8085]

Here is my person service application.yml

spring:
  cloud:
    kubernetes:
      ribbon:
          mode: SERVICE
organizationservice:
        ribbon:
            MaxAutoRetries: 2
            MaxAutoRetriesNextServer: 0
            OkToRetryOnAllOperations: true
            ServerListRefreshInterval: 2000
            ConnectTimeout: 10000
            ReadTimeout: 1000

person ms dependecy

compile "org.springframework.cloud:spring-cloud-starter-kubernetes-all"
compile('org.springframework.cloud:spring-cloud-starter-netflix-ribbon')

upon checking the logs for organization pod. No calls have been made to it.

Edit 1: Upon changing the log level for feign in person service I found that JWT token is begin passed by default. I solved the issue using filters but the same application was working with out filters when I was using not using spring cloud kubernetes.
