Track: Delivering on the Promise of Containers

10:35am - 11:25am

The Highs and Lows of Stateful Containers

As modern organizations have rapidly embraced containers in recent years, stateful applications have proven tougher to transition into this brave new world than other workloads. When persistent state is involved, more is required both of the container orchestration system and of the stateful application itself to ensure the safety and availability of the data. 

This talk will walk through my experiences trying to reliably run a distributed database on Kubernetes, optimize its performance, and help others do the same in their heterogeneous environments. We’ll look at what kinds of stateful applications can most easily be run in containers, which Kubernetes features and usage patterns are most helpful for running them, and a number of pitfalls I encountered along the way. Finally, we’ll ponder what’s missing and what the future may hold for stateful containers.

Disenchantment: Netflix Titus, its Feisty Team, and Daemons

Disenchantment is a Netflix show following the medieval misadventures of a hard-drinking princess, her feisty elf, and her personal demon. In this talk, we will follow the story of Netflix’s container management platform, Titus, which powers critical aspects of the Netflix business (video encoding & streaming, big data, recommendations & machine learning, and other workloads). We’ll cover the challenges growing Titus from 10’s to 1000’s of workloads. We’ll talk about our feisty team’s work across container runtimes, scheduling & control plane, and cloud infrastructure integration. We’ll talk about the demons we’ve found on this journey covering operability, security, reliability and performance.

The 10 Kubernetes Commandments

We've been in the operations and development game for years; it has made us animals. We've learned there are rules for success, so we created a manual. This is a step-by-step checklist to get your Kubernetes game on track. (and maybe your manager off your back?) 

In this session, Carlos and Bryan are going to share ideas that your teams can employ to make working Kubernetes less of a chore and more of a way of life. The topics of this session cover tips and hints ranging from bootstrapping your clusters, to managing custom workloads, to using the Kubernetes API as your applications' API. These ideas will be paralleled with lessons we learned growing up in Hip Hop culture. 

This session has two goals. First, we'd like to introduce the canonical Kubernetes day 0, day 1, and day 2 experiences. We'll take those experiences and interlace them with real-world tips that can be employed by users of Kubernetes.

We'll be exploring topics from booting Kubernetes clusters to running complex workloads as a list of 10 items. If you'd like any more information (or our list of 10 topics), let me know.

2:55pm - 3:45pm

Control Theory In Container Orchestration

Containers offer 2 central promises: software as encapsulated and reproducible units. A key corollary of those promises is the ability to schedule and manage containers automatically. This session aims to give attendees a solid understanding of leveraging or building container orchestration using feedback signals. 

We’ll apply engineering control theory to key container management scenarios. This will cover basic principles of observing systems, controller design, and PID controllers. In particular, we’ll dive into container scaling controllers, using both first principles and proven designs from Kubernetes and Mesos.

4:10pm - 5:00pm

Chaos Engineering with Containers

Chaos Engineering is the practice of running thoughtful planned experiments to reveal weakness in our systems. In this session, Ana discusses the benefits of using Chaos Engineering to inject failures in order to make your container infrastructure more reliable. She will also share how to improve your container monitoring and observability.  Lessons learned from running Chaos Engineering GameDays with Gremlin customers will also be shared as case studies.
