PuppetConf (Part 7, Finale): Challenges With Docker in Production [Video]
Docker is great for dev machines because it ''just works.'' But as we know, it isn't so clean and neat in production. Here are the challenges and some ideas to beat them.

The way IT operations teams deploy and manage their infrastructure is constantly evolving. The latest developments in containers and container scheduling technologies such as Docker, Kubernetes, and Mesos, especially, have gotten a lot of attention, and more and more people in IT and software development are adopting these solutions — and deploying infrastructure in the cloud — all the time.
Managing this modern infrastructure isn't a trivial task — and that's exactly what Puppet is here for. In this post, I am summarizing for you some of the excellent talks that were given at PuppetConf 2016 on container technologies and how Puppet fits into this new IT ecosystem. These talks — all captured on video — really are a must-watch if you are using these technologies, and even more so if you are thinking about adopting them.
If you want to start this video series from the beginning, take a look at why it's important to care about container management, the challenges with container configuration, running Puppet software in Docker, Kubernetes for Sysadmins, using Puppet with Kubernetes and OpenShift, and scaling Puppet on ECS with Docker and Terraform.
Challenges With Docker in Production
Corey Quinn from the Quinn Advisory Group gave a talk about the problems one can encounter while using Docker in production.
Using Docker on development machines, we don't need to worry about a lot of things that we would need to worry about in production. In production, we need to consider things like networking, scheduling, rolling deployments, monitoring, configuration changes, etc., which we don't need to consider on a development machine, because it "just works." Corey discusses various challenges that Docker presents in production.
