How Google Cloud Hosts and Manages Kubernetes at Scale [I] - David Aronchick, Google
A breakdown of what we do on Google Cloud to make running Kubernetes great, both managing large amounts of Kubernetes clusters, and what we do on behalf of users to ensure everything is running in the optimal configuration. Folks will be able to take away our best practices and apply them to their own installations.

Steward, the Kubernetes-Native Service Broker [A] - Gabe Monroy, Deis
No application is an island. Most applications interact with a diverse set of services, not all of which run on a Kubernetes cluster. How do you manage access to both on and off cluster resources? Join Gabe Monroy, CTO of Deis, for a discussion about service catalogs, explicit service bindings, and how they can help you rationalize heterogeneous computing environments. We will end with a demo of Steward, an open source service broker for Kubernetes.

Rise of the Machines [B] - Anne Currie, Microscaling Systems
What does a containerised, orchestrated world look like and who will be in control? Are server-less and state-less the opposite of what they appear? Can we trust the AIs? If you ever ask yourself this kind of question, you'll probably enjoy this talk.

Kubernetes Day 2: Cluster Operations [I] - Brandon Philips, CoreOS
How do you keep a Kubernetes cluster running long term? Just like any other service, you need a combination of monitoring, alerting, backup, upgrade, and infrastructure management strategies to make it happen. This talk will walk through and demonstrate the best practices for each of these questions and show off the latest tooling that makes it possible. The takeaway will be lessons and considerations that will influence the way you operate your own Kubernetes clusters.

How We Run Kubernetes in Kubernetes, aka Kubeception [I] - Timo Derstappen, Giant Swarm
At Giant Swarm our users want fully-managed Kubernetes clusters without any limitations (incl. privileged access to the nodes). We deploy and manage these clusters either in our data center, in the preferred cloud of the customer, or even on-premise. Both for ourselves as well as for enterprise customers we need full isolation between clusters and a easy way to manage and update clusters without downtime.

In this talk we explain how we use a “mother” Kubernetes to deploy and manage fully-isolated and encrypted Kubernetes clusters for different customers or teams - aka Kubeception. Our model treats (inner) Kubernetes clusters as a third party resource and manages them with a custom controller. This way we have an automated way of provisioning and managing clusters without additional tooling or complex monitoring setups. Further, through our API, we are to be able to spin clusters up and down on demand, scale them, update them, keep track of which clusters are available, and be able to assign them to organizations and teams flexibly.

Elephants on Automatic: HA Clustered PostgreSQL with Helm [I] - Josh Berkus, Red Hat & Oleksii Kliukin, Zalando
Kuberntes and Helm are not only the best way to automate high-availability PostgreSQL clusters, they're also the easiest! Join us to find out how you can deploy several different PostgreSQL cluster types using Helm in 30 minutes or less.

Helm is a package manager of choice for the Kubernetes community. PostgreSQL is the most advanced open-source database and is quickly becoming the relational database of choice for numerous developers running their applications in the cloud. In this talk, we are going to show two different types of fully automated PostgreSQL clusters with Helm: Spilo and CitusDB. Spilo provides automated failover and support services for single-master database clusters, and CitusDB provides sharded, big-data PostgreSQL.

We will demonstrate both of these types of clusters (and possibly others), explain how the Helm charts which set them up work, and how you can modify them to support your production environment.

Kubernetes-Defined Monitoring [I] - Gianluca Borello, Sysdig
Over the past few years we’ve all learned how Kubernetes can dramatically change the process of deploying an application, improve reliability, and accelerate operations. As Kubernetes matures, I believe it will have ripple effects on other elements of DevOps, including monitoring.

In this talk, we’ll explore the question, “What if Kubernetes also defined and automated monitoring?” We’ll explore some of the available tooling to answer questions like:

*What are the right ways to instrument Kubernetes minons & pods?
*How do you effectively get visibility into aggregate microservices vs just containers?
*How can Kubernetes automate the act of setting up monitoring dashboards and alerts?
*How can teams use Kubernetes to allow them to isolate monitoring data more effectively, so that the right data is exposed only to the right people?

This will be a demo-driven session, based on a real Kubernetes environment, using a variety of tools at our disposal. Attendees should have a basic understanding of Kubernetes deployments as well as monitoring requirements.

IPVS for Scaled Private Cloud Load Balancing [I] - Kimberly Messimer, Comcast VIPER
In this talk, we discuss how Comcast VIPER addresses network-scaling bottlenecks using IPVS as a load balancer. We discuss the benefits including enabling us to achieve over 500Gbit/s egress from a modest Kubernetes cluster as well as dynamic VIP allocation.

Using a tool we’ve written in-house called Kube2IPVS, which utilize Kubernetes config maps, we can assign an ingress IP address and port to a Kubernetes service, and our load balancer will automatically reconfigure, with no downtime, to load balance traffic into a service.

We go into technical detail in this presentation, starting with a brief overview of IPVS and why it’s useful. We will then descend into the requirements surrounding L2 adjacency and why ARP is your frenemy. We’ll discuss how we addressed the challenges of running IPVS internal to Kubernetes, including IPVS master and backend co-location.

Finally, we'll highlight how port forwarding is not possible using IPVS in direct-reply mode, and then discuss how Kube2IPVS manages iptables rules to route packets directly into Kubernetes service chains, effectively bypassing this restriction.

We expect to have Kube2IPVS open-sourced in 2017.
