# Usage Examples:
|
||||
#
|
||||
# 1. Mount as environment variables:
|
||||
# envFrom:
|
||||
# - configMapRef:
|
||||
# name: <app-name>-config
|
||||
#
|
||||
# 2. Mount as files:
|
||||
# volumeMounts:
|
||||
# - name: config
|
||||
# mountPath: /etc/app
|
||||
# volumes:
|
||||
# - name: config
|
||||
# configMap:
|
||||
# name: <app-name>-config-file
|
||||
#
|
||||
# 3. Mount specific keys as files:
|
||||
# volumes:
|
||||
# - name: nginx-config
|
||||
# configMap:
|
||||
# name: <app-name>-multi-config
|
||||
# items:
|
||||
# - key: nginx.conf
|
||||
# path: nginx.conf
|
||||
#
|
||||
# 4. Use individual environment variables:
|
||||
# env:
|
||||
# - name: LOG_LEVEL
|
||||
# valueFrom:
|
||||
# configMapKeyRef:
|
||||
# name: <app-name>-config
|
||||
# key: LOG_LEVEL
