Unable to bootstrap SpringBoot application with ConfigMap in kubernetes

Question

I'm using Spring Boot 3 and I have an application-configmap ConfigMap in Kubernetes workspace which has application.yaml file and I would like to bootstrap the application using the ConfigMap.

In bootstrap-preproduction.yml, I have:

spring:
  cloud:
    config:
      enabled: false
    kubernetes:
      config:
        namespace: workspace
        sources:
          - name: application-configmap
    bootstrap:
      enabled: true

During the pod startup, I have logs where the config map is located but yml file is skipped and application does not start as its finding the DB configs.

I believe, there is no issue in the application.yml file as it was working correctly with the config server. I migrated this to the config map, and it has not been loaded during the bootstrap of the application.
