  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
  
  Wait for the pod to run:

  `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.
