The config volume is then mounted at /redis-master by spec.containers[0].volumeMounts[1].\n\nThis has the net effect of exposing the data in data.redis-config from the example-redis-config ConfigMap above as /redis-master/redis.conf inside the Pod.\n\nExamine the created objects\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get pod/redis configmap/example-redis-config\n```\n\nYou should see the following output\n\nBounded code example (external data; do not execute automatically):\n```text\nNAME        READY   STATUS    RESTARTS   AGE\npod/redis   1/1     Running   0          8s\n\nNAME                             DATA   AGE\nconfigmap/example-redis-config   1      14s\n```\n\nRecall that we left redis-config key in the example-redis-config ConfigMap blank\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl describe configmap/example-redis-config\n```\n\nYou should see an empty redis-config key\n\nBounded code example (external data; do not execute automatically):\n```shell\nName:         example-redis-config\nNamespace:    default\nLabels:       <none>\nAnnotations:  <none>\n\nData\n====\nredis-config:\n```\n\nUse kubectl exec to enter the pod and run the redis-cli tool to check the current configuration\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl exec -it pod/redis -- redis-cli\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
