Making the Most Out of Kubernetes Audit Logs - Laurent Bernaille & Robert Boll, Datadog
The Kubernetes audit logs are a rich source of information: all of the calls made to the API server are stored, along with additional metadata such as usernames, timings, and source IPs. They help to answer questions such as “What is overloading my control plane?” or “Which sequence of events led to this problematic situation?”. These questions are hard to answer otherwise—especially in large clusters. At Datadog, we have been running clusters with 1000+ nodes for more than a year and during that time, the audit logs have proved invaluable.

In this talk, we will first introduce the audit logs, explain how they are configured, and review the type of data they store. We will then demo a functioning setup and show a few different types of analysis techniques. Finally, we will describe in detail several scenarios where they have helped us to diagnose complex problems.

Take Envoy Beyond a K8s Service Mesh - to Legacy Bare Metal and VMs + More - Steve Sloka & Steven Wong, VMware
Envoy’s mission is to extract network and communication security code from applications in a way that developers and users can deploy components that just work no matter where they run or what hosts them.

This session will show how to leverage Envoy to achieve interoperation of applications and services, split across Kubernetes and traditional VM or bare metal hosts. We’ll look at how to incrementally bring Kubernetes into an existing application architecture based on existing VM or bare metal applications and services.


Specific examples will demonstrate:
- Using Contour with Envoy as an Ingress and load balancer solution with a richer feature set than some common alternatives
- Sending requests from VM workloads to Kubernetes services
- Direct requests to services running on a VM from Kubernetes
- Dynamical traffic steering - K8s and VM workloads at the same time

Living with the Pathology of the Cloud: How AWS Runs Lots of Clusters - Micah Hausler, Amazon
Disk speed screeches to a crawl, packets get dropped, connections time out: welcome to the cloud! Most of the time the cloud "just works", but when it doesn’t, how does Kubernetes and etcd handle failure? In this talk Micah will discuss considerations for building and configuring cloud native systems for failure including how Amazon EKS’s architecture and design accounts for outages and dependency failures. Micah will also cover and lessons learned from managing lots and lots of Kubernetes and etcd for customers around the world.

Building the Cloud Native Kernel: Kubernetes Release Engineering - Tim Pepper & Stephen Augustus, VMware
Is Kubernetes a kernel or distribution? Yes! It is necessarily both!

CRD’s, out-of-tree cloud providers, and CNI/CSI/CRI abstractions evolve Kubernetes’ core toward an extensible kernel.

At 2017, KubeCon NA Tim Hockin and Michael Rubin started a conversation on formalizing “Kubernetes upstream as a distro”, proposing we clean up thinking/processes, define tools/standards, incentivize distros to stay close. They argued for a Kubernetes reference distribution focused on correctness and stability.

So where is it?

After a slow start, we have momentum in 2019 to improve conformance, API stability, and better documented support stances. However to understand why we don’t (yet) have an upstream reference distro, we need to dive deep on build/release/test tooling.

This talk will summarize Kubernetes distro issues/advances and potential contribution areas for individuals and companies.

Scaling Kubernetes to Thousands of Nodes Across Multiple Clusters, Calmly - Ben Hughes, Airbnb
In under a year, Airbnb went from 600 Kubernetes nodes across a couple handcrafted clusters to over 5000 nodes on tens of clusters. Successful adoption of Kubernetes by services led to more and faster adoption leading to challenges of scale. Facing this, Airbnb switched to a multiple production cluster architecture to get around single cluster scalability limits and ensure ample capacity for services.

This process increased the consistency of the cluster configurations while reducing manual operations. This talk will discuss the problems that were faced during scaling, the shape of the solutions, specific approaches that worked well (and didn’t), and how this was accomplished without a drastic shift away from existing pre-Kubernetes infrastructure tooling. A key result was reducing the time to create a new, production-ready cluster from over a week to under an hour.

Running Large-Scale Stateful Workloads On Kubernetes at Lyft - Surinder Singh & Anmol Khurana, Lyft
Along with core services, K8s at Lyft also forms the base to run a large variety of data processing stateful data processing jobs which includes Spark, Flink and other jobs via various ML and Data processing pipelines.

At Lyft, K8s has become the driver for the majority of our data processing needs running 10s of thousands of concurrent jobs. Operating the platform at this scale presents an unique set of challenges which get more complex with highly variable load pattern.

In this talk, the speakers will share their journey through some of these challenges and learnings.
- Potential pitfalls of running stateful jobs on K8s.
- Knobs/tweaks to optimize K8s for stateful jobs.
- Running k8s in a cloud environment.
- Building a fault-tolerant self-healing system with multiple K8s clusters underneath.

Talk will also focus on optimizations done to support the widely used workloads at Lyft.

To Infinite Scale and Beyond: Operating Kubernetes Past the Steady State - Austin Lamon, Spotify & Jago Macleod, Google
Operating large distributed systems at significant scale is challenging. Most discussions focus on scalability either at a single point in time under sustained load, or explore challenges related to changes in incoming traffic.

But running distributed systems at scale is about more than steady states and transitions between them. What is equally challenging and tends to get overlooked are the operational challenges of running at scale: upgrading many and/or large clusters; deploying applications to and across multiple clusters in a reasonable way; balancing freedom and consistency across multiple teams. In this case study, Google and Spotify share some of the challenges of running Kubernetes at Scale, together with concrete solutions, patterns, and common pitfalls we have found together. Intended for cluster operators and developers from organizations of any size and on any provider.

Wait, People Run Kubernetes on Mainframes? - Elizabeth K. Joseph, IBM
When you think of container orchestration mainframes probably aren't the first thing that come to mind.

But modern mainframes run Linux as a first class citizen and KVM can be used for virtualization, opening a whole world of open source tooling integration via libvirt and related virtualization tooling. The careful observer may have already discovered that the mainframe architecture (s390x) is one of the architectures that's built for every Kubernetes release.

How did this come to be? Who uses these mainframe builds of Kubernetes? Why would you run a distributed container orchestration service on a platform that's a symbol of the monolith we're looking to leave? Drawing upon my work with distributed systems and containers, including time spent on OpenStack, Apache Mesos and Kubernetes, and my new experience with mainframes, this talk answers all of those questions and more.

The Myth of the Monocluster - Matt Silverlock, Google
Building out a single monolithic Kubernetes cluster and trying to migrate all the things rarely, if ever, works out, and Kubernetes doesn't change that. It becomes harder to gather non-conflicting requirements, or avoid scope creep as new teams have what seem like reasonable asks (to them). Not to mention the technical challenges & increased blast radius of a big cluster.

How can we start with smaller teams, help them migrate and operationalize their clusters, learn from the inevitable mistakes, document the shortcuts, and use that as the framework for future teams?

Let's talk through what we need to ask ourselves in order to migrate to Kubernetes, how to divide & conquer (our clusters), and some lessons learnt from working with large organizations.

Handling Risky Business: Cluster Upgrades - Puneet Pruthi, Lyft
Have you ever had to upgrade your Kubernetes clusters to update to a new release version, push new features or patch critical security vulnerabilities? Did it ever feel daunting to live update API masters or etcds? Can you automate such an operation?

We hope to share our musings at Lyft in solving the complexity of automating cluster upgrades and how that is incorporated into the design for - k8srotator - a Kubernetes custom controller.

As multiple components operating in cohesion make a cluster healthy, there are numerous points of failure that can occur during an upgrade cycle. Although there are varied ways of operating a Kubernetes cluster, the issues encountered during the process are common.

Attendees will walk away with knowledge about different cluster upgrade failures scenarios and ways to automate such operations without being in constant fear of losing the cluster state.

Am I Using It Right? Checking Best Practices on Live Kubernetes Clusters - Varsha Varadarajan & Adam Wolfe Gordon, DigitalOcean
While Kubernetes is stable, best practices for using it are a moving target. Some are generally applicable, others unique to a particular configuration or platform. Following best practices helps ensure workloads stay running as expected through cluster maintenance and upgrades, but checking them can feel like playing whack-a-mole in the dark.

This talk introduces a new open source tool, clusterlint, that checks compliance with best practices. Unlike other linters that work on deployment manifests, clusterlint identifies risks and problems in running Kubernetes clusters, making it useful for finding potential problems before performing cluster maintenance.

We'll discuss what clusterlint checks, why, how it works, how we use it in DigitalOcean's managed Kubernetes product to warn users of danger, and future plans for the tool.

The Gotchas of Zero-Downtime Traffic /w Kubernetes - Leigh Capili, Weaveworks
Noticing your customers receive 503's every now-and-then?
Do they spike when you're updating your app or rotating your k8s cluster nodes?
Maybe you used to have this problem -- then you added some strange settings and it's mostly working now…

What most people need from Kubernetes regarding web-traffic is a repeatable but under-documented combo of esoteric, non-default options.

We'll walk through the basic needs of shaping traffic and apply that knowledge to the states of compute, rollout, and canonical networking we see with k8s.
Expect tidbits about CRI, CNI, Ingress, and the design trade-offs present in Kubernetes and its API's.

You’ll leave this session knowing how to keep your apps serving successful requests for a myriad of edge-cases.

The Elephant in the Kubernetes Room: Team Interactions at Scale - Manuel Pais, Independent
Kubernetes helps us tame sprawling microservices architectures and address increased operational complexity. Kubernetes gives developers abstractions and APIs to deploy and run their services.

Yet, the elephant in the room is that to run, maintain and evolve Kubernetes clusters, we need more ops expertise and most likely a dedicated team to do so.

The question that begs to be asked is if we risk going back to pre-DevOps isolation between Dev and Ops teams? Is the tradeoff between better operational tools and introducing a new dependency layer on the path to production for application teams worthwhile? Are we making life easier for application teams or instead reducing their end-to-end ownership?

Manuel will then introduce Team Topologies, a balanced approach for thinking about teams responsibilities and interactions which can help get the most value out of your Kubernetes adoption.

Governance on K8s: How to Solve Ownership, Metering & Capacity Planning - Micheal Benedict & Yongwen Xu, Pinterest
Pinterest is a cloud first visual discovery engine that serves over 250MM users. To support this scale, there are thousands of services running on tens of thousands of hosts, processing 300+PB of data. We operate large kubernetes clusters across several availability zones, across regions. The cluster is auto scaled with support for pod level auto-scaling. Finally,to effectively utilize resources within the clusters, we operate heterogeneous workloads on a kitchen sink of instance types. Given this,
1.Who owns what?
2.What is driving utilization?
3.How do we plan capacity effectively with minimal overhead?

In this talk, we will share how we built a governance platform to address the above through defining canonical ownership, metering resource utilization (at various granularities) + reporting and finally a policy enforcement mechanism (ex, pre-emption, placement, etc).
