When mounting a ConfigMap as a volume, how can you access individual keys as separate files inside the container?

• A. All keys automatically appear in a single file
• B. Map each key to its own file under the mount point
• C. You cannot map keys to filenames
• D. You must convert the ConfigMap to a Secret first

Answer: (B)

When you mount a ConfigMap as a volume, each key in the ConfigMap becomes its own file inside the mounted directory, with the file name matching the key. This means you can read individual configuration values by opening the corresponding file under the mount path. If you need different file names, you can customize the mapping with the items field, but by default every key is exposed as a separate file under the mount point.
