ClusterAPI: A Guide to Get Started - Katie Gamanji, American Express

In the past years, Kubernetes has been the nucleus of container orchestration frameworks. With the growing number of microservices, managing clusters at scale has become an imperative requirement. Additionally, from a technological landscape standpoint, the cloud platform teams are highly focused on delivering scalable, reliable and highly available platforms.
At Condé Nast, this constitutes in having a stable and coherent approach to deploy, manage and upgrade multiple Kubernetes clusters that are distributed globally. Also, it is imperative to keep the life-cycle management of the clusters consistent across all regions. Henceforth, this talk aims to present an overview of how Condé Nast prototypes tools, such as ClusterAPI, to ensure a sustainable cluster provisioning mechanism.

Managing a Managed Kubernetes Platform - Annegies van 't Zand & Wiender Sarup, Nationale Nederlanden

Over the past year Nationale Nederlanden (NN) has built a managed Kubernetes platform for their DevOps teams.

Now, a year later, we are managing over twenty Kubernetes clusters that are running multiple production workloads. Although Kubernetes is the main component, it turned out that lifecycle management and reliable delivery of changes to in-use platforms proved to be the most challenging part. All-in-all there are fifteen components that provide all the platform features and services, so we had to get creative to make sure that we kept up to date with all of them.

In this talk we will share our solutions for setting up a platform delivery pipeline and the lifecycle management of our platform components. Fan-in/fan-out cluster deployments, platform integration tests, version dashboards and feature flagging are some of the subjects that we will address.

Kubernetes DNS Horror Stories (And How to Avoid Them) - Laurent Bernaille, Datadog

DNS is one of the Kubernetes core systems and can quickly become a source of issues when you’re running clusters at scale. For over a year at Datadog, we’ve run Kubernetes clusters with thousands of nodes that host workloads generating tens of thousands of DNS queries per second. It wasn’t easy to build an architecture able to handle this load, and we’ve had our share of problems along the way.

This talk starts with a presentation of how Kubernetes DNS works. It then dives into the challenges we’ve faced, which span a variety of topics related to load, connection tracking, upstream servers, rolling updates, resolver implementations, and performance. We then show how our DNS architecture evolved over time to address or mitigate these problems. Finally, we share our solutions for detecting these problems before they happen—and identifying misbehaving clients.

Banking on Kubernetes, the Hard Way, in Production - Miles Bryant & Suhail Patel, Monzo Bank

Have you ever wondered what it takes to deploy and operate Kubernetes at scale, in production? Self hosted clusters often have a bad reputation as a complex and costly choice when compared to managed services. Let’s look at an alternative viewpoint and evaluate the tradeoffs.

Monzo started self hosting Kubernetes out of necessity a few years ago when managed services were in their infancy. In this talk, Miles and Suhail will explain why Monzo has chosen to continue operating their own clusters, and how this can be a viable option.

This talk discusses Monzo’s experiences with operating, upgrading, customising and configuring the control plane, networking and cloud integrations. We think this has been the best choice, but we also want to discuss the challenges we’ve faced along the way - like the time when network policies took down a large chunk of Monzo's cluster.

Reimagining the Worldwide LHC Computing Grid on Kubernetes - Lukas Heinrich, CERN & Alessandra Forti, University of Manchester

At CERN, the home of the web, the Large Hadron Collider at CERN hosts some of the largest physics experiments ever constructed. The distributed infrastructure built over the last 20 years -- the World-wide LHC computing grid (WLCG) would today be described a federated, multi-cloud and multi-cluster deployment, mostly made up of a diverse set of research institute batch systems deployed on bare-metal or VMs. The rise of containers is an opportunity to reimagine the WLCG deployed on Kubernetes. In this talk we will cover how we leverage CNCF tools in this transition. Using e.g. containerd snapshotters for worldwide image distribution, Helm GitOps for reproducible configuration of multi-cluster setups and our deployment of services and batch workloads in that system. In a demo, we will deploy a member of the federation which will then receive workloads to analyze subatomic collision data.

20,000 Upgrades Later: Lessons From a Year of Managed Kubernetes Upgrades - Adam Wolfe Gordon, DigitalOcean

Upgrading to a new release is one of the most disruptive operations we regularly inflict on our Kubernetes clusters. There are multiple strategies for doing an upgrade, but they all require rescheduling workloads and restarting cluster components.

We started offering upgrades on our managed Kubernetes platform, DigitalOcean Kubernetes Service (DOKS), in May 2019. Since then, our customers have kicked off about 20,000 automated patch and minor release upgrades on their clusters. Most of those upgrades went well, but some didn't and we've learned a few things from the ones that went wrong.

In this talk we will share lessons from a year of automated Kubernetes upgrades: what we got right, what we got wrong, workloads that caused us trouble, and changes we've made to make the process smoother. We hope these lessons will help others avoid pain in their Kubernetes upgrades.

In-place Upgrade Noway! Blue/Green Your Way to a New Kubernetes Version - Ricardo Aravena, Rakuten

Since its introduction, Kubernetes has had a relentless pace of innovation and a significant release every three months. For an organization, it may be challenging to keep pace with new features and their Kubernetes clusters up to date. Furthermore, the constant change of the Kubernetes API + CRDs may be a barrier to minimizing downtime.

This session will showcase using different tools with automation to update the major version of your cluster using a blue/green approach. Can we take advantage of a GitOps approach using open-source tools like Flux and Keiko? How do we change manifests to support the new API? How can we verify and add more security to the upgrades?

The audience will come away with a pragmatic understanding of how to make use of different open-source tools and processes to make Kubernetes upgrades seamless with minimal to no downtime in production.

Help! Please Rescue Not-ready Nodes Immediately - Xiaoyu Zhang, Alibaba & Di Xu, Ant Financial

For a Kubernetes cluster, nodes are crucial to make pods running properly. So it is indispensable to monitor nodes status and detect node problems. Node problem detector (NPD), an open source project in Kubernetes community, is a good answer to address this issue. Nowadays NPD has already been well accepted and widely used in production environments.

Actually identifying the problem is only the first step. What we need to do next is to handle those problems and rescue the nodes.

In this talk, we will list common problems and share how we establish rules to decide whether a node is ready or not and how to fix them if recoverable. Moreover, we will introduce some use scenarios on how we make a 99.9% uptime guarantee with ten thousand nodes in a single cluster. We will share some experience on how to recover the nodes within 10 minutes as well.

Autoscaling and Cost Optimization on Kubernetes: From 0 to 100 - Guy Templeton, Skyscanner & Jiaxin Shan, Amazon

One of the great promises of Kubernetes is the ability to scale your applications and infrastructure dynamically based on demand whilst optimising cost no matter where clusters run. Autoscaling workloads and clusters without compromising the performance or availability of your applications is not always simple though.

At Skyscanner, use of the Cluster Autoscaler (CA), Horizontal Pod Autoscaler (HPA) and Vertical Pod Autoscaler (VPA) have helped meet traveller demand in a cost effective way. Guy and Jiaxin will walk through hard earned autoscaling lessons, going from the basics to advanced features. This will include using custom metrics with the HPA, the CA’s expanders, scaling from zero, labeling and balancing between node groups to handle different use cases and challenging to scale applications. They will also cover a number of other useful community tools to help with autoscaling.

Zero Downtime Deployments: Controlling Application Rollouts and Rollbacks - Christopher Hanson, RX-M LLC

Kubernetes provides several types of automation controllers to deploy and manage applications at scale. Each exposes features that provide for zero downtime upgrades and rollbacks but not all controllers are created equal. Deployments provide the widest application compatibility but work best with stateless applications; the aptly named StatefulSet controller provides guarantees that benefit stateful applications, but how do the features of these controllers behave in practice?

Learn about these and other Kubernetes controller types through a series of demonstrations that will reveal their features, benefits, and drawbacks. The session will also explore the primitives that enable granular control over rollouts so that you can choose the settings that work best for your application.
