If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. kubeadm: Restructure internal config usage and fix bugs **What this PR does / why we need it**: - Moves the generic LoadYAML function from the versioned, external API package to a helper library so it can be consumed more easily - Makes the upgrading code use the internal version of the API (which always should be used anyway) - Moves all config-loading code to `configutil`, together with the migration code needed. This way we have everything in one centralized place, instead of duplicating that logic N times. - Makes `kubeadm init` use `configutil` for the reasons mentioned above. This PR is needed in order to support multiple external API groups (like v1alpha2) **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Part of https://github.com/kubernetes/community/pull/2131 **Special notes for your reviewer**: This PR depends on: - https://github.com/kubernetes/kubernetes/pull/63782 - https://github.com/kubernetes/kubernetes/pull/63783 **Please review only the last (third) commit** **Release note**: ```release-note NONE ``` @kubernetes/sig-cluster-lifecycle-pr-reviews @liztio |

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.
