265# Usage Examples:
266#
267# 1. Mount as environment variables:
268# envFrom:
269# - configMapRef:
270# name: <app-name>-config
271#
272# 2. Mount as files:
273# volumeMounts:
274# - name: config
275# mountPath: /etc/app
276# volumes:
277# - name: config
278# configMap:
279# name: <app-name>-config-file
280#
281# 3. Mount specific keys as files:
282# volumes:
283# - name: nginx-config
284# configMap:
285# name: <app-name>-multi-config
286# items:
287# - key: nginx.conf
288# path: nginx.conf
289#
290# 4. Use individual environment variables:
291# env:
292# - name: LOG_LEVEL
293# valueFrom:
294# configMapKeyRef:
295# name: <app-name>-config
296# key: LOG_LEVEL
