instruction: Create a Dockerfile for configuration

  from the object configuration file.For subsequent object management, use replace exclusively.kubectl replace -f <kind>_<name>.yaml
  Defining controller selectors and PodTemplate labelsWarning:Updating selectors on controllers is strongly discouraged.The recommended approach is to define a single, immutable PodTemplate label
  used only by the controller selector with no other semantic meaning.Example label:selector:
   matchLabels:
   controller-selector: "apps/v1/deployment/nginx"
  template:
   metadata:
   labels:
   controller-selector: "apps/v1/deployment/nginx"
