   Let's use `redis-config` ConfigMap to create our `redis.conf` configuration file in the pod `redis-pod`. It maps the ConfigMap to the volume where the configuration resides:
   
  -    kubectl apply -f ./templates/redis-pod.yaml
  +    $ kubectl apply -f ./templates/redis-pod.yaml
  +    pod "redis-pod" created
   
   Wait for the pod to run:

  Create a ConfigMap:
  
      kubectl apply -f ./templates/redis-configmap.yaml
  
  `redis-configmap.yaml` is a standard resource configuration file. It defines the configuration information as:
  
  ```
  data:
    redis-config: |
      maxmemory=2mb
      maxmemory-policy=allkeys-lru
  ```
  
  The configuration data is stored in the main key `data`. `redis-config` is an attribute inside this key where the configuration information for the Redis pod is defined as key-value pairs.
  
  Get the list of ConfigMaps:
  
  ```
  $ kubectl get configmap
  NAME           DATA      AGE
  redis-config   1         4m
  ```
