Automatic merge from submit-queue (batch tested with PRs 50911, 50839) Fix admission plugin registration **What this PR does / why we need it**: The current registration of admission plug-ins happen too late so the command line help is not yielding correct/useful information to users. This is already causing confusion as mentioned in some issues. This patch fixes it by moving plugins.go down to options package because "plugins" in this context are themselves options for users. Registration of plugins is not an expensive operation and it is already done in most execution paths. **Which issue this PR fixes** fixes #50833 **Special notes for your reviewer**: There might be other thoughts on how to better align this with other efforts. This PR is leaving them to future work. For example: in future, we may want to revisit these plugins and migrate them to the shared apiserver repo when appropriate. **Release note**: I'm not sure if a release note is needed for this. Maybe there is a need. ```release-note ```
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.
