Automatic merge from submit-queue kubeadm: Enable the Node Authorizer/Admission plugin in v1.7 **What this PR does / why we need it**: This is similar to https://github.com/kubernetes/kubernetes/pull/46796, but for kubeadm. Basically it was a part of https://github.com/kubernetes/kubernetes/pull/46796, but there were some other upgradability and compability concerns for kubeadm I took care of while working today. Example: ```console $ kubeadm init --kubernetes-version v1.7.0-beta.0 [kubeadm] WARNING: kubeadm is in beta, please do not use it for production clusters. [init] Using Kubernetes version: v1.7.0-beta.0 [init] Using Authorization mode: [RBAC Node] ... $ sudo kubectl --kubeconfig=/etc/kubernetes/kubelet.conf get secret foo Error from server (Forbidden): User "system:node:thegopher" cannot get secrets in the namespace "default".: "no path found to object" (get secrets foo) $ echo '{"apiVersion":"v1","kind":"Node","metadata":{"name":"foo"}}' | sudo kubectl create -f - --kubeconfig=/etc/kubernetes/kubelet.conf Error from server (Forbidden): error when creating "STDIN": nodes "foo" is forbidden: node thegopher cannot modify node foo ``` **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes # **Special notes for your reviewer**: Depends on https://github.com/kubernetes/kubernetes/pull/46864 (uses that PR as a base, will rebase once it's merged) Please only review the second commit. Will also fix tests in a minute. **Release note**: ```release-note kubeadm: Enable the Node Authorizer/Admission plugin in v1.7 ``` @mikedanese @liggitt @pipejakob @roberthbailey @jbeda @timothysc |

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
If you are less impatient, 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.
