About this event

This month! We are teaming up with StLGo to live-stream a highly relevant talk on developing custom Kubernetes controllers.

This event will be streamed remotely on Crowdcast! We will also be raffling out credits to the CNCF swag store, which is getting some new updates including project face masks.

Writing General Purpose Kubernetes Controllers in Go

As Kubernetes becomes ubiquitous as the operating system for the data-center, organizations are extending the platform to build their own internal PaaS. This generally consists of creating new CustomResourceDefinitions (CRDs) and corresponding controllers to manage them. As a platform grows, it is common for different classes of resources to evolve. For instance, a platform may support provisioning different types of compute resources that each require their own CRD, but are reconciled in very similar ways. Writing new reconcilers with complex logic for every primitive in an infrastructure platform can be cumbersome and error-prone.
Fortunately, making use of common interfaces can make this burden much lighter. In this talk we will explore how to write robust general purpose Kubernetes reconcilers using embedded types, code generation, duck types.

Presenter: Daniel Mangum, @hasheddan

Daniel is a software engineer at Upbound where he works on the open source Crossplane project. He also serves on the Kubernetes release team, and is an active contributor to the Kubernetes project and multiple other open source efforts. He hosts a biweekly live stream show, The Binding Status, focused on extending Kubernetes, building Crossplane, and enabling a multicloud future.

This event will be virtual! As we get closer to the date, we will provide details and URL to access the talk.
