Leverage LXD/LXC with Kubernetes [A] - Lin Sun, IBM
Do you want to increase the density of your Kubernetes workers? We have run some experiments with Kubernetes workers in LXC containers managed by LXD. Come to hear our experience and challenges during the experiment!

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.

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.

Switching From External Load Balancing to consul & ingress [I] - Dan Wilson, Concur
At Concur we integrated our kubernetes clusters to our own internal F5 ecosystem which worked well for internal data center deployments but turned out to be cumbersome when trying to maintain a consistent setup for our cloud environments. We'll discuss what the issues are that we faced and the new architecture that we're using which combines consul for dns service discovery with kubernetes ingress in a multi kubernetes cluster design.
