Changing the default port of the embedded server does not change the K8S probes default port

[waynemorphic]

I was checking out the Spring Boot Quickstart provided under the Maven package and found something peculiar that I would like a little help with. The default port of the embedded server is 8080. However, I changed it to 8081 underresources\application.yaml with the configuration:

server:
  port: 8081

This follows that, building the Spring Boot application with mvn spring-boot:run serves the application on Tomcat's port 8081.

2024-03-16 18:55:29.067  INFO 3498 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat initialized with port(s): 8081 (http)

However, when running the command that creates K8S resources descriptors, i.e mvn clean k8s:resource -Pkubernetes, then there is a discrepancy between the ports:

[INFO] k8s: jkube-controller: Adding a default Deployment
[INFO] k8s: jkube-service: Adding a default service 'spring-boot' with ports [8081]
[INFO] k8s: jkube-healthcheck-spring-boot: Adding readiness probe on port 8080, path='/actuator/health', scheme='HTTP', with initial delay 10 seconds
[INFO] k8s: jkube-healthcheck-spring-boot: Adding liveness probe on port 8080, path='/actuator/health', scheme='HTTP', with initial delay 180 seconds
[INFO] k8s: jkube-service-discovery: Using first mentioned service port '8081' 

What I have tried so far with the invaluable help of @rohanKanojia was adding the following property in my POM file:

<properties>
    <jkube.version>${project.version}</jkube.version>
    <jkube.generator.spring-boot.webPort>8081</jkube.generator.spring-boot.webPort>
  </properties>

However, the above port discrepancy persists. Guidance on this will be helpful. Thank you

This seems like a bug
