Kubernetes deep dive: API Server – part 1

Kubernetes deep dive: API Server - part 1

Welcome to the Kubernetes deep dive blog post series. We, that is, Stefan Schimanski (Engineering) and Michael Hausenblas (Advocacy), will dive into specific aspects of Kubernetes and how they’re utilized within OpenShift. If you’re interested in the inner workings of Kubernetes and how to debug it, this blog post series is for you. Also, if you want to extend Kubernetes or start contributing to the project, you might benefit from it. Familiarity with Go is an advantage but not a hard requirement to follow along.

In this installment we start with a general introduction of the Kubernetes API Server, provide some terminology and explain the API request flow. Future posts will cover storage-related topics and extensibility points of the API Server.

How to use GPUs in OpenShift and Kubernetes

How to use GPUs in OpenShift and Kubernetes

Running general-purpose compute workloads on Graphics Processing Units (GPUs) has become increasingly popular recently in a wide range of application domains, mirroring the increased ubiquity of deploying applications in Linux containers. Thanks to community participant Clarifai, Kubernetes became able to schedule workloads depending on GPUs beginning with version 1.3, enabling us to develop applications that are on the cutting edge of both trends with Kubernetes or OpenShift.
