- MySQL
- Memcached
- Redis
- Sidekiq
- Monit (to keep Puma and Sidekiq runnig)

set :linked_files, fetch(:linked_files, []).push('config/database.yml', 'config/secrets.yml')
set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'public/system')
set :keep_releases, 5Add the target host:
