How To Centralize Your Docker Logs with Fluentd and ElasticSearch on Ubuntu 14.04
[Fluentd](https://www.fluentd.org) is an open source data collector designed to unify logging infrastructure. It is designed to bring operations engineers, application engineers, and data engineers together by making it simple and scalable to collect and store logs.
