Extract a Specific Key from a ConfigMap: You can use jq or yq to parse JSON or YAML output to get specific values. For example, to get the value of a specific key in a ConfigMap:

kubectl get configmap <configmap-name> -n <namespace> -o jsonpath=‘{.data.<key-name>}’

Replace <key-name> with the name of the key you want to query.
