KubeVirt - Kubernetes, Virtualization and Your Future Data Center [I] - Itamar Heim & Fabian Deutsch, Red Hat
Kubernetes is a great orchestration tool for containers, but why stop there? Containers and virtual machines are going to co-exist in the data center. Let’s re-envision our virtualization and cloud solutions with Kubernetes as a single underlying platform.

We’ll introduce KubeVirt - a project to converge the future data center using Kubernetes as its infrastructure. We will cover how we are implementing a caring and stateful environment to run pet VMs in containers on top of Kubernetes - without contradicting its core assumptions. We will also be discussing gaps and how we plan to tackle those, drawing on our experience with KVM and and caring for pet VMs (and cats) for many years. The session will also include a demo of how we are doing this today and where we want to go next.

Kubernetes Operators: Managing Complex Software with Software [I] - Josh Wood, CoreOS & Jesus Carrillo, Ticketmaster
The Kubernetes container orchestrator scales and connects stateless applications quite easily. Stateful applications can require more work. Databases, caching systems, and file stores are harder to dynamically manage with data intact, and sometimes come with their own notion of clustering. Operators automate these tasks. Operators are Kubernetes agents that know how to deploy, scale, manage, and even upgrade complex applications.

In this talk, we'll illustrate the Operator concept, showing how Operators are built atop the Kubernetes third-party resources mechanism, with a close examination of the open source etcd Operator. We'll demonstrate Operators in action, including the extension of the Operator concept to upgrading Kubernetes control plane components themselves. The audience will learn how to deploy Operators, and how to begin developing Operators to manage their own stateful applications.

Network-independent ACLs: Why Security Shouldn't Depend on Your Network [I] - Bernard Van De Walle, Aporeto
The conventional view is that Security and ACLs are implemented in the network, through a set of typical firewall rules that rely on the IP and Port number.

In Kubernetes, everything is a label and pod communications are defined as a set of labels allowed to communicate with each other. (Through the definition of network policies).
This model fully abstracts the pod network information (IP/Port) from the pod's identity (pod's labels).

With the traditional approach, the NetworkPolicies are implemented by the Kubernetes networking backend (Flannel, Calico, ...) that translates the policies into a set of IPs/Ports that need to be constantly updated.

However, another approach is possible by using the labels associated with each pods directly as metadata on the networking stack (transparently from the networking backend). NetworkPolicies then become a simple API-level authentication scheme that is completely independent from the network backend.

This talk will go over the pros and cons of each model, describing specific use-cases where it makes sense to use the one or the other.

It will introduce a new way of implementing those NetworkPolicies that doesn't rely at all on network primitives, but only on the set of labels associated to each pod.

Networking should be used for reachability between cluster nodes.
but security and network policies should not always be tied to your networking.

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.

Success of CRI: Bringing Hypervisor Based Container to Kubernetes [I] - Lei Zhang, HyperHQ
CRI, aka Container Runtime Interface, is the new mechanism designed to plug any container runtime in Kubernetes. In this presentation, I will introduce how we introduce the hypervisor based container into Kubernetes as native container runtime by using CRI. And enables users to serve their customers directly with virtualized containers, instead of wrapping them inside of full blown VMs. CRI design principles and implementation details will be explained. As well as the essential differences between Kubernetes and other projects like SwarmKit and how hyper.sh made the choice. Today, many developers are not comfortable with Linux containers as an effective boundary, and requires for a stronger degree of isolation, particularly for those running in a multi-tenant environment. We believe HyperContainer with Kubernetes is one of the best answers.

Sched.net: A Network-Aware Kubernetes Scheduler [I] - Akash Gangil & Salvatore Orlando, VMware
Different workloads have different optimal scheduling requirements. For instance, a video streaming microservice would need higher network bandwidth than a microservice running the codec. Kubernetes exposes an interface to build a custom scheduler. In this talk, we will show how better scheduling decisions can be made with information about the network topology. The scheduler would make pod scheduling decisions as a function of network health, in addition to other resources like cpu and memory predicates used by the default scheduler.


The talk would highlight:
* How kubernetes empowers the users to build their own custom scheduler and challenges that come along with it.
* Why we needed sched.net over the current default scheduler?
* Demonstrate how better scheduling decisions can be made, if the scheduler is also aware of the current network state with a simple demo described below.


Demo setup would consist of kubernetes with OVN as a networking backend using the ovn-kubernetes plugin. It provides a well defined translation between Kubernetes and OVN logical network abstractions. Ex: namespace → logical switch, pod → logical switch port. Sched.net would be implemented by adding a predicate function which would determine “network health” from information gathered from OVN controller.
