Cluster Deployment Patterns - KubeCon [clear filter]

Hybrid Cloud Powered by Kubernetes [I] - Aparna Sinha, Eric Brewer & Matthew DeLio, Google
Open Source Software (OSS) is great because it gives us freedom. OSS users by nature want to roll their own on premises, and use best-of-breed services in public clouds an without lock-in. Fortunately, Kubernetes runs everywhere so developers and operators don't need to learn new technologies to run hybrid and multi-cloud applications.

In this talk, we will demonstrate the use of two new extensibility features in Kubernetes to connect legacy on-premises applications and managed public cloud services with services running on Kubernetes in both places, creating an environment where users can have the best of all worlds. We will show the type of use cases this technology enables using examples from Google's cloud platform.

Zero Configuration Pattern of Kubernetes on Bare Metal [A] - Rob Hirschfeld, RackN
In recent releases, we've enabled node admission and configuration APIs that eliminate configuration requirements for Kubernetes workers. This allows cluster operators to add and remove nodes from clusters without a configuration management tool driving the process. This fully automate node management behavior allows physical data centers to be much more cloud-like and lights-out.

In this session, we'll run this process as a demo and decompose the various parts that must work together for success. We'll discuss the specific APIs and how to implement them in a coordinated way that ensures node security and minimizes workload disruption. We'll also discuss how to improve node security by using trusted platform modules (TPM). By the end of the session, operators will be able to duplicate the steps on their own to learn the process.

While we have a focus on bare metal infrastructure for this session, the lessons learned are equally usable on cloud infrastructure.

Cost-effective Compute Clusters with Spot and Pre-emptible Instances [I] - Bich Le & Arun Sriraman, Platform9
Kubernetes and Spot/Pre-emptible Instances (SPIs) are arguably a match made in heaven. Traditionally, the uncertainty of SPIs (they can be terminated at any time due to price fluctuations) have made managing them tricky, and restricted them to specific workloads and use cases.

Kubernetes, in contrast, not only handles node failure very well, it has trained developers and architects to design applications to tolerate and even embrace failure. The prospect of Kubernetes abstracting the complexities of SPIs is now a reality, enabling applications to take advantage of low-cost compute across different clouds and possibly vendors.

The purpose of this talk is to educate the audience on strategies for making the most out of this powerful combination. Specifically, we will discuss these topics:

1. What are spot bidding strategies, and what is their cost vs. predictability trade-off?
2. What class of Kubernetes applications would benefit the most from SPIs?
3. Available Kubernetes mechanisms (e.g taints/tolerations, affinity, availability zones) for placing applications based on their tolerance with SPIs
3. Implementation strategies (e.g. blending multiple autoscaling groups to satisfy both SPI-optimized applications vs. applications that are more mission-critical or stateful)
4. What out-of-the box solutions exist, either free or commercial?
5. How to take abstract away clouds from different regions and vendors, allowing workloads to always take advantage of the best available pricing?

The talk concludes with real-world test results involving multiple use cases and configurations, giving the audience an idea of the potential cost savings and trade-offs (if any) of combining Kubernetes and SPIs.

Self-Hosted Kubernetes: How and Why [I] - Diego Pontoriero, CoreOS
How Kubernetes is deployed and managed has changed since the first release of the project. From configuration management systems and unit files to deploying Kubernetes using Kubernetes, a lot has changed. Self-hosted Kubernetes has many benefits as a deployment option, and this talk will highlight those benefits, as well as explain the history and nuances of making self-hosted Kubernetes possible.

In this talk I will describe what self-hosted Kubernetes means, why it exists, how it came into existence, and what you need to know if you're running a self-hosted cluster. Many tools now deploy self-hosted clusters including bootkube and kubeadm, so knowledge of how this works can be very important for anybody running a Kubernetes cluster.

What are the benefits of self-hosting? How does it work? What do I need to know if I'm administering a self-hosted cluster?

All those questions and more will be discussed in detail in this talk. In addition, I will discuss how various projects and products take advantage of the many benefits of self-hosting, such as Tectonic.

Cluster-in-a-Box: Deploying Kubernetes on lxd [B] - Rye Terrell, Canonical & Marco Ceppi, The Silph Road
Deploying kubernetes on top of lxd allows you to build and operate one or more clusters within a single machine, virtual or bare metal. Architect your cluster to be used for development, testing, and more. Once you're satisfied, create a machine image of your host VM for fast, reproducible deployments.

Using Kubo to Manage your Kubernetes Clusters [I] - Oleksandr Slynko & Brendan Nolan, Pivotal
Kubo is an OSS project developed jointly by Pivotal and Google. It provides an uniform way to instantiate, deploy, and manage highly available vanilla Kubernetes clusters using BOSH - on GCE, vSphere, AWS, Openstack and Azure.

Using BOSH and Kubo to manage Kubernetes gives self healing, easily upgradeable clusters with managed secrets rotation. Cluster creation is simplified to the point where clusters can be created and destroyed for use in development or sandbox environments.

In this presentation, Brendan and Oleksandr will demonstrate deployment across multiple IAASes, cluster healing, cluster upgrade and cluster creation.
