Kubernetes - ConfigMaps

You want to mount only specific keys from a ConfigMap named app-config as files inside a container at /etc/config. Which volume configuration snippet achieves this?

Avolumes: - name: config-volume configMap: name: app-config exclude: - unused_key

Bvolumes: - name: config-volume configMap: name: app-config items: - key: database_url path: db_url - key: log_level path: log_level

Cvolumes: - name: config-volume secret: name: app-config items: - key: database_url path: db_url

Dvolumes: - name: config-volume configMap: name: app-config keys: - database_url - log_level

Step-by-Step Solution

Solution:

Step 1: Understand selective key mounting
Kubernetes allows selecting specific keys from a ConfigMap using the items field with key and path.
Step 2: Identify correct syntax
volumes: - name: config-volume configMap: name: app-config items: - key: database_url path: db_url - key: log_level path: log_level correctly uses items with key-path pairs to mount only chosen keys as files.
Final Answer:
volumes: - name: config-volume configMap: name: app-config items: - key: database_url path: db_url - key: log_level path: log_level -> Option B
Quick Check:
Use items with key and path to select keys [OK]

Quick Trick: Use 'items' with key and path to mount specific keys [OK]

Common Mistakes:

Using 'keys' instead of 'items' for selection
Confusing ConfigMap with Secret for this purpose
Trying to exclude keys instead of selecting them
