spring-cloud-kubernetes: FeignClients do not currently work without the spring-cloud-kubernetes-ribbon implementation

Using the latest version of Spring Cloud Kubernetes without the spring-cloud-kubernetes-ribbon implementation causes FeignClients to not work:

com.netflix.client.ClientException: Load balancer does not have available server for client: my-awesome-service

Services are running in the same Kubernetes cluster, same namespace and was working with the spring-cloud-kubernetes-ribbon implementation.

The current project is set up with Hoxton.SR5 and :


    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
    </dependency>

No, you have to change the url in your project to https

Aha! Fixing the permissions did make the sample app work now! Thanks for all the help @piomin. Also thanks for pointing me to:

<dependency>
    <groupId>io.fabric8</groupId>
    <artifactId>kubernetes-server-mock</artifactId>
    <scope>test</scope>
</dependency>

Thanks @spencergibb! Based on what @ryanjbaxter mentioned, I think eventually we will not be able to use spring-cloud-kubernetes-ribbon so I’m kinda trying to understand how this would work on the next major version. Should I be using spring-cloud-starter-loadbalancer instead?
