Kubernetes / Code Walkthroughs

Rob Kielty and Dan Mangum kick off Flake Finder Fridays, a new Kubernetes community livestream where we explore building, testing, CI and all other aspects of delivering Kubernetes artifacts to end users in a consistent and reliable manner. In this first episode, Rob and Dan are going to look at recent failures in a Kubernetes build job and chat a little bit about why it was failing, what tooling is used to build Kubernetes, and the infrastructure underlying all Kubernetes CI jobs.

@liggitt walks us through finding and fixing test flakes

When Slack seems like it’s going too fast, and you just need a quick answer from a human...

Meet Our Contributors gives you a monthly one-hour opportunity to ask questions about our upstream community, watch interviews with our contributors, and participate in peer code reviews.

Deep Dive: Auth SIG - Mo Khan & Matt Rogers, Red Hat

We present a thorough walkthrough of the Kubernetes authentication and authorization codebase, where we will cover interface contracts and give specific examples of how they are implemented in Kubernetes.  The audience will also be given a high level overview of the request processing pipeline.  The generic nature of these interfaces will be explored along with a look into areas where Kubernetes has a strong opinion on the implementation specifics such as service accounts and the node authorizer.  As a case study, the OpenShift auth stack will be discussed.  OpenShift’s use of OAuth for authentication and role based access control for authorization will lead into discussions around token delegation, auditing, access controlled resource lists, etc.

Deep Dive: Kubernetes (UI) SIG - Jeffrey Sica, University of Michigan & Sebastian Floreks, Loodse

The Kubernetes Dashboard is the primary way non-cloud-hosted Kubernetes clusters are managed and is a great introductory tool in a new cluster-admin's belt. The Dashboard, much like Kubernetes itself, is a complex beast with many moving parts. With a front-end written in Angular, and a back-end written in go, the project has a complex set of needs to support development. This session will dive into both the front-end and back-end development with the Dashboard as well as outline progress with the 2019 SIG-UI Roadmap.

This tour is about API groups and API objects and how they come to life in the Kubernetes API server: Golang types, code generation, conversions, roundtrip tests, schemes, registries and strategies, validation and finally the API REST endpoints. This is for everybody adding new APIs, or trying to understand how our machinery works today and also for those who want to build aggregated API servers.

Presenter: Stefan Schimanski, Red Hat

Stefan Schimanski (@sttts) walks us through how the kubernetes codebase is organized on github.
