An application expects configuration as files under /etc/app. How should a ConfigMap typically provide those files, and what must developers remember about updates?
Select an answer to reveal the explanation.
Short Explanation
A ConfigMap volume is like dropping printed settings sheets into a folder the app already reads. New sheets can show up later, but the app might need a nudge (reload/restart) before it notices.
Full Explanation
ConfigMaps can be mounted as volumes so each key is presented as a file in the container filesystem. Kubelet can update projected files when the ConfigMap changes, but many applications cache config at startup and still need a reload or restart. emptyDir does not replace ConfigMap projection, and Services/PVCs are not the standard way to present config files.
