instruction: Create a Dockerfile for configuration
output: ```dockerfile
  from the ConfigMap to create as files
   items:
   - key: "game.properties"
   path: "game.properties"
   - key: "user-interface.properties"
   path: "user-interface.properties"
   A ConfigMap doesn't differentiate between single line property values and
  multi-line file-like values.
  What matters is how Pods and other objects consume those values.For this example, defining a volume and mounting it inside the demo
  container as /config creates two files,
  /config/game.properties and /config/user-interface.properties,
  even though there are four keys in the ConfigMap. This is because the Pod
  definition specifies an items array in the volumes section.
  If you omit the items array entirely, every key in the ConfigMap becomes
  a file with the same name as the key, and you get 4 files.Using ConfigMapsConfigMaps can be mounted as data volumes. ConfigMaps can also be used by other
  parts of the system, without being directly exposed to the Pod. For example,
  ConfigMaps can hold data that other parts of the system should use for configuration.The most common way to use ConfigMaps is to configure settings for
  containers running in a Pod in the same namespace. You can also use a
  ConfigMap separately.For example, you
  might encounter addons
  or operators that
  adjust their behavior based on a ConfigMap.<h3 id=using-configmaps-as-files-
