The spring cloud gateway app can not start up after upgrade form 1.1.10-RELEASE to 2.1.3

[yumingtao]

env: spring-cloud-starter-gateway 3.1.3 spring-cloud-kubernetes-discovery 2.1.3

When the app starts, gets below error.

" Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'reactiveCompositeDiscoveryClient' defined in class path resource [org/springframework/cloud/client/discovery/composite/reactive/ReactiveCompositeDiscoveryClientAutoConfiguration.class]: Unsatisfied dependency expressed through method 'reactiveCompositeDiscoveryClient' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kubernetesReactiveDiscoveryClient' defined in class path resource [org/springframework/cloud/kubernetes/discovery/KubernetesDiscoveryClientAutoConfiguration$Reactive.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.client.discovery.ReactiveDiscoveryClient]: Factory method 'kubernetesReactiveDiscoveryClient' threw exception; nested exception is org.springframework.cloud.kubernetes.discovery.DiscoveryServerUrlInvalidException: spring.cloud.kubernetes.discovery-server-url must be specified and a valid URL. "

I want to confirm that, in my spring cloud gateway app, I use spring cloud Kubernetes discovery to get services from K8s API server, it works well with 1.1.x-RELEASE. And for upgrading to 2.0.0+ version, if it means I need to deploy a discovery server and config the discovery server URL in my spring cloud gateway app yaml? Thanks.

Sounds like you want to use spring-cloud-starter-kubernetes-client or spring-cloud-starter-kubernetes-fabric8.

Hi, I just want the spring cloud gateway discovering the service deployed in the K8s cluster by adding some configuration in spring-boot properties, so when the HTTP request comes, the gateway can route the request to the correct service for processing.

Configuration as below.

spring.cloud.discovery.client.health-indicator.enabled=false spring.cloud.kubernetes.discovery.enabled=true spring.cloud.gateway.discovery.locator.enabled=false spring.cloud.gateway.discovery.locator.lower-case-service-id=true spring.cloud.kubernetes.reload.enable=true spring.cloud.kubernetes.reload.mode=polling spring.cloud.kubernetes.reload.period=5000 spring.cloud.kubernetes.client.namespace=dev

spring.cloud.gateway.routes[0].id=my-service1-route spring.cloud.gateway.routes[0].uri=lb://my-service1:5010 spring.cloud.gateway.routes[0].predicates[0]=Path=/my-service1/**

spring.cloud.gateway.routes[1].id=my-service2-route spring.cloud.gateway.routes[1].uri=lb://my-service2:5020 spring.cloud.gateway.routes[1].predicates[0]=Path=/my-service2/****

Right you have the wrong dependency on your classpath, you need to choose one of the two I listed above.

I will hava a try

@ryanjbaxter @yumingtao I'm facing the same issue. I created this test project: https://github.com/rcbandit111/mockup/blob/master/src/main/resources/application.yml

More description: https://stackoverflow.com/questions/78249919/discoveryserverurlinvalidexception-spring-cloud-kubernetes-discovery-server-url

Can you advice any possible solution, please?

Ah, I commented on the stackoverflow, but you miss at least this simple thing :) You have it as :

spring:
  cloud:
    kubernetes:
      discovery-server-url: "spring-cloud-kubernetes-discoveryserver.default.svc:8761"

and it should be:

spring:
  cloud:
    kubernetes:
        discovery:
             discovery-server-url: "spring-cloud-kubernetes-discoveryserver.default.svc:8761"

Also please upgrade and let's see from there...

It solved the issue. Thanks
