ribbon.mode SERVICE doesn't work

[DmitryevichD]

Describe the bug I sets a ribbon property spring.cloud.kubernetes.ribbon.mode: SERVICE to my application.yml, but my client sends request by Pod IP address. After that I downloads this project and don't find KubernetesRibbonMode in the code. Also I don't find in the code SERVICE and POD rules.
I looked at examples from the documentation but I didn't find the use of these setting.

Please, explain how it work or give a link to the code with KubernetesRibbonMode

springCloudVersion = 'Greenwich.SR2' springBootVersion = '2.1.6.RELEASE'

Thanks.

Sample

spring:
  profiles:
    active: dev
  application:
    name: otp
  cloud:
    kubernetes:
      ribbon:
        mode: SERVICE

What version of Spring Cloud are you using?

[DmitryevichD]

springCloudVersion = 'Greenwich.SR2' springBootVersion = '2.1.6.RELEASE'

[spencergibb]

This project no longer has direct ribbon integration

[DmitryevichD]

Thanks. Now I'm updating my spring cloud version and try it. I want to understand how it work. but I can't find source code for POD or SERVICE mode. I was looking in this project and spring-cloud-commons and kubernetes-client-project, but nothing. Can you help me find these sources?

[DmitryevichD]

I update spring version to

• springBootVersion = '2.2.6.RELEASE'
• springCloudVersion = 'Hoxton.SR4' but nothing changed

When my service is starting my request to config service performed by POD IP, but I set mode: SERVICE

Hi @spencergibb - Thanks for indicating that ribbon is not supported. Please can you advice any specific reason why this was removed? This was working with the below versions,

        springBootVersion = '2.2.4.RELEASE'
        springCloudVersion = 'Hoxton.SR1'

We upgraded our application to the below versions and found that k8s integration is broken,

        springBootVersion = '2.2.7.RELEASE'
        springCloudVersion = 'Hoxton.SR4'

Also please advice what we can do to support ribbon discovery client with k8s as below dependency is no longer there in kubernetes-all ?

<dependency>	
    <groupId>org.springframework.cloud</groupId>	
    <artifactId>spring-cloud-starter-kubernetes-ribbon</artifactId>	
</dependency>

[jayzch]

[OlgaMaciaszek]

@jayzch this got just merged into master and we are also working to get it available for the coming Hoxton release (https://github.com/spring-cloud/spring-cloud-kubernetes/pull/610).
