Spring boot readiness probe givining out of service in kubernetes pod though locally running fine

Question

Both my liveness and readiness shows status up when I am testing them locally. Running my service in kubernetes is a different story. Seems like the liveness is also working fine but readiness is giving 503. I have tried to test it from my docker image which is also working fine.

configuration properties used:

    management.endpoint.health.probes.enabled=true
    management.endpoint.metrics.enabled=true
    management.endpoints.web.exposure.include=*
    management.endpoint.prometheus.enabled=true
    management.metrics.export.prometheus.enabled=true
    management.endpoint.health.group.readiness.include=*
    management.endpoint.health.group.readiness.show-details=always
    management.endpoint.health.group.liveness.include=ping
    management.endpoint.health.group.liveness.show-details=never    

Log from pod:
