  from dropping them.You can use kubectl replace -f to update a live object according to a
  configuration file.kubectl replace -f <filename|url>How to delete objectsYou can use kubectl delete -f to delete an object that is described in a
  configuration file.kubectl delete -f <filename|url>Note:If configuration file has specified the generateName field in the metadata
  section instead of the name field, you cannot delete the object using
  kubectl delete -f <filename|url>.
  You will have to use other flags for deleting the object. For example:kubectl delete <type> <name>
  kubectl delete <type> -l <label>
  How to view an objectYou can use kubectl get -f to view information about an object that is
  described in a configuration file.kubectl get -f <filename|url> -o yamlThe -o yaml flag specifies that the full object configuration is printed.
  Use kubectl get -h to see a list of options.LimitationsThe create, replace, and delete commands work well when each object's
  configuration is fully defined and recorded in its configuration
  file. However when a live object is updated, and the updates are not merged
  into its configuration file, the updates will be lost the next time a replace
  is executed. This can happen if a controller, such as
  a HorizontalPodAutoscaler, makes updates directly to a live object. Here's
  an example:You create an object
