Config server and eureka server in same application: tries to connect to localhost:8761

Question

I have a spring-boot application which I use to setup a spring cloud config server and a eureka server in development and testing environments. Strangely the application always tries to connect to localhost:8761, even though I have eureka.client.registerWithEureka set to false.

How can I deactivate this?

The error:

ERROR 3144 --- [et_localhost-12] c.n.e.cluster.ReplicationTaskProcessor   : Network level connection to peer localhost; retrying after delay

My only class looks like this:

@EnableEurekaServer
@EnableConfigServer
@SpringBootApplication
public class MyApplication {
  public static void main(String[] args) {
    SpringApplication.run(MyApplication.class, args);
  }
}

The application.yml:

server:
  port: 8888

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
  server:
    waitTimeInMsWhenSyncEmpty: 0
    renewal-percent-threshold: 0.49

security:
  basic:
    enabled: true
  user:
    password: mypassword


spring:
  jmx:
    default-domain: ${spring.application.name}
  cloud:
    config:
      server:
        git:
          uri: https://example.com/myrepo.git
          username: username
          password: password
          clone-on-start: true
          search-paths: '{application},{application}/{profile}'

endpoints:
  jmx:
    domain: ${spring.application.name}
    unique-names: true

In the bootstrap.yml I have only the application name set.

Versions:

spring-cloud-netflix-eureka: 1.1.6, spring-cloud-config-server: 1.1.3

Solution 1

Could you try to change your configuration like below

eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
    service-url:
      defaultZone: http://localhost:8888/eureka

You specify server.port: 8888. So your eureka is running on 8888 port. But you didn't specify any service-url for eureka. So I think that your eureka server is trying to replicate to localhost:8761 because it's default and you didn't specify service-url for eureka.

Solution 2

Please Use 8761 port for your Eureka server as below.

server:
  port: 8761
eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false

Here we’re configuring an application port – 8761 is the default one for Eureka servers. We are telling the built-in Eureka Client not to register with ‘itself’, because our application should be acting as a server.

Solution 3

For me, below properties that worked for me.

eureka.client.registerWithEureka= false
eureka.client.fetchRegistry= false
eureka.server.maxThreadsForPeerReplication=0

Solution 4

It seems that eureka tries to connect to itself despite the below settings:

eureka.client.register-with-eureka=false 
eureka.client.fetch-registry=false

you have two options to fix that 1-Keep the default port of eureka 2-Add below to your application.properties of your eureka server eureka.server.maxThreadsForPeerReplication=0
