Writing General Purpose Kubernetes Controllers in Go - Daniel Mangum

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.

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.

LIGHTNING TALK:
Understanding pseudo-versions, moving to Go 1.13 and what is in Go 1.14

As of Go v1.13 extracting a module from a version control system, the go command performs additional validation on the requested version string, as a result, any module which has multiple pseudo-versions for one commit hash will fail. In this talk, we will explain the version validations that have been enforced with Go v1.13 and how to fix them so that you can upgrade to Go v1.13 seamlessly. This talk will also cover what is new in Go 1.14 for Go module.

An experienced software engineer, Mitali has designed, developed and led challenging software projects involved cloud technologies, Big data , web ,devops in both large and small tech companies. As a Community Software Engineer at JFrog she is responsible for developing features for Gocenter and other projects related to Community. She has also been engaging with Go Community authors to make them aware of the security aspect of their modules and help them to resolve it. She loves exploring and adopting new technologies.

This StLGo Virtual Meetup from May 27, 2020 was originally streamed live on Crowdcast.
