At the November DOXLON, Facebook gave us an in-depth look into the way we have managed containers over the past 8 years, and why a complete overhaul is coming, with an entirely new control group system. Epam Systems showed us how to use the ELK stack together with Beats Plugin data shippers for system metrics, along with monitoring multiple Docker containers. Neil Chowdhury at Strft focused on how they are using Splunk and data models for collaboration, and the need for semantic logging.
The topic of the October 2016 DOXLON Meetup was container orchestration. The goal: shed light on and compare existing technologies: Kubernetes, Mesos and Docker Swarm. The Meetup started with lighting talks about Kubernetes and Mesos in production at two large companies, Pearson and Schibsted. This was followed by a panel discussion, moderated by our CTO Steven Acreman.
Battling mess is an ongoing struggle that has plagued most of my career. Docker presents an opportunity to explosively increase the chance of mess. You can of course reduce mess with a local registry, proper build process and sane use of docker files. Unfortunately, if my experiences pre-docker-era are anything to go by, things will not be done properly.
