Remove KUBE_API_VERSIONS Fixes https://github.com/kubernetes/kubernetes/issues/63102 KUBE_API_VERSIONS is an attempt to control the available serialization of types. It pre-dates the idea that we'll have separate schemes, so it's not a thing that makes sense anymore. Server-side we've had a very clear message about breaks in the logs for a year "KUBE_API_VERSIONS is only for testing. Things will break.". Client-side it became progressively more broken as we moved to generic types for CRUD more than a year ago. What is registered doesn't matter when everything is unstructured. We should remove this piece of legacy since it doesn't behave predictable server-side or client-side. @smarterclayton @lavalamp @kubernetes/sig-api-machinery-bugs ```release-note KUBE_API_VERSIONS is no longer respected. It was used for testing, but runtime-config is the proper flag to set. ``` |

Kubernetes

Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide, and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
