DetectUnsupportedVersion is somewhat uncomfortable, complex and inefficient function to use. It takes an entire YAML document as bytes, splits it up to byte slices of the different YAML sub-documents and group-version-kinds and searches through those to detect an unsupported kubeadm config. If such config is detected, the function returns an error, if it is not (i.e. the normal function operation) everything done so far is discarded. This could have been acceptable, if not the fact, that in all cases that this function is called, the YAML document bytes are split up and an iteration on GVK map is performed yet again. Hence, we don't need DetectUnsupportedVersion in its current form as it's inefficient, complex and takes only YAML document bytes. This change replaces DetectUnsupportedVersion with ValidateSupportedVersion, which takes a GroupVersion argument and checks if it is on the list of unsupported config versions. In that case an error is returned. ValidateSupportedVersion relies on the caller to read and split the YAML document and then iterate on its GVK map checking if the particular GroupVersion is supported or not.

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.
