instruction: Create a Dockerfile for configuration
output: ```dockerfile
  from a key-value pair:cat <<EOF >./kustomization.yaml
  configMapGenerator:
  - name: example-configmap-2
   literals:
   - FOO=Bar
  EOF
  The generated ConfigMap can be checked by the following command:kubectl kustomize ./
  The generated ConfigMap is:apiVersion: v1
  data:
   FOO: Bar
  kind: ConfigMap
  metadata:
   name: example-configmap-2-g2hdhfc6tk
  To use a generated ConfigMap in a Deployment, reference it by the name of the configMapGenerator.
  Kustomize will automatically replace this name with the generated name.This is an example deployment that uses a generated ConfigMap:# Create an application.properties file
  cat <<EOF >application.properties
  FOO=Bar
  EOF
  
  cat <<EOF >deployment.yaml
  apiVersion: apps/v1
  kind: Deployment

   app: my-app

  cat <<EOF >./kustomization.yaml

  Generate the ConfigMap and Deployment:kubectl kustomize ./
  The generated Deployment will refer to the generated ConfigMap by name:apiVersion: v1

   application.properties: |
