The AWS OpsWorks Stacks service reached end of life on May 26, 2024 and has been disabled for both new and existing customers. We strongly recommend customers migrate their workloads to other solutions as soon as possible.

This example assumes that you have Ruby on Rails application that uses Redis. To access the configuration file, you can add the redis gem to your Gemfile and create a Rails initializer in config/initializers/redis.rb as follows:

REDIS_CONFIG = YAML::load_file(Rails.root.join('config', 'redis.yml'))
$redis = Redis.new(:host => REDIS_CONFIG['host'], :port => REDIS_CONFIG['port'])

Then create an app to represent your application and deploy it to the Rails App Server layer's instances, which updates the application code and runs generate.rb to generate the configuration file. When you run the application, it will use the ElastiCache Redis instance as its in-memory key-value store.
