Spring Boot 3.2.0 with Spring cloud 2023.0.0 | Spring Cloud API Gateway not starting on Openshift about spring-cloud-kubernetes HOT 11 OPEN

Can you provide a complete, minimal, verifiable sample that reproduces the problem? It should be available as a GitHub (or similar) project or attached to this issue as a zip file.

from spring-cloud-kubernetes.

It is just vanilla with spring boot and spring cloud without any code. It has below dependencies which are managed by the BOM

• spring-cloud-starter-gateway
• spring-cloud-kubernetes-client-all
• spring-boot-starter-actuator
• spring-cloud-starter-loadbalancer

The catch here is, the same piece of application works fine in my local machine but it doesn't get boot up in Openshift.

Below are the configs which are added in application.yaml

spring:
  cloud:
    kubernetes:
      enabled: true
    gateway:
      enabled: true
      discovery.locator.enabled: true
      discovery.locator.lower-case-service-id: true

Let me know if any thing else is needed, as the machine where the application lies won't allow to upload any piece of code. If needed we can have a discussion on this.

It would still be helpful to provide the exact code to reproduce the problem so we can try and replicate it. Have you tried this on a vanilla k8s cluster?

from spring-cloud-kubernetes.

I created a pure vanilla application with spring cloud gateway and it worked fine for me.
To deep dive into the issue, I tried by adding the library and configuration which we had in our gateway application.
I found the issue occur when I enable the FeignClients with @EnableFeignClients annotation at that time the system is not starting up.

Are you aware about the configuration that need to be done here?

from spring-cloud-kubernetes.

That shouldn’t require any extra configuration that I’m aware of

from spring-cloud-kubernetes.

Any idea about the below statement mentioned in the RELEASE_NOTES can this create the issue?
As after disabling the EnableFeignClient annotation it started working fine.
Is it something feign is not compatible with the reactive web we get in gateway, or something else...

[Switched to default eager @FeignClient attribute resolution. If you would like to go back to lazy attributes resolution (for example, for tests with Spring Cloud Contract integration), set spring.cloud.openfeign.lazy-attributes-resolution to true.]

from spring-cloud-kubernetes.

I am not sure how you are combining OpenFeign and the Gateway, but no they are not compatible. OpenFeign is blocking and the Gateway needs is non-blocking.

from spring-cloud-kubernetes.

So this can be the reason that application not started?
But the same application started in my local, any idea what can be done?

from spring-cloud-kubernetes.

Doesn’t sound like it but it’s impossible for me to tell since I don’t have anything to reproduce the problem with
