Load balancer does not contain an instance for the service [EKS environment]

[billelmehdi]

Hi, I have few services deployed in EKS and some of them have issues to be reached.

I have this exception:

2022-06-01 11:27:39.383  WARN 1 --- [nio-8080-exec-3] o.s.c.l.core.RoundRobinLoadBalancer      : No servers available for service: backend-service

caller application.yaml:

server:
  port: 8080
  shutdown: graceful
spring:
  config:
    activate:
      on-profile: prod
  lifecycle:
    timeout-per-shutdown-phase: 10s
feign:
  client:
    config:
      default:
        connectTimeout: 10000
        readTimeout: 50000

I also added both annotations to main class:

@EnableDiscoveryClient
@EnableFeignClients("com.wheels.search")

caller class:

@FeignClient(name="backend-service")
public interface ServicesProxy {...}

here is an extract of the pom:

Hello @billelmehdi; The Spring Cloud Kubernetes version compatible with Spring Cloud 2020.0.4 is 2.1.3. You should not need to specify it at all, but just get it from the bom (dependencyManagement). Please fix that and verify if the issue persists.
