## 
# This sample adds an ElastiCache cluster to the environment.
#  It does not provide credentials for accessing that elasticache cluster or on-instance scripts.
#
# Customers would generally not edit this file.
# Instead, they would have another file sitting in the same directory (or anywhere) with 
#  an option-settings section such as the following (all of these are showing the default value)
#
# option-settings:
#  "aws:elasticbeanstalk:customoption" :
#     CacheNodeType : cache.m1.small
#     NumCacheNodes : 1
#     Engine : memcached
