This simplified guide to logging Docker to Elasticsearch shows you how to send logs of containers into Elastic. Although there are many tutorials on to logging Docker to Elasticsearch, this one is different from all as it uses syslog-ng. Visualize them on a nice dashboard in Kibana. And you can download it all at the end of the post!
Update: I moved the chapters about parsing and visualizing NGINX / Apache access logs in Kibana into a dedicated post. I hope it will improve readability of both subjects.
