Automatic merge from submit-queue (batch tested with PRs 54331, 54655, 54320, 54639, 54288). 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>. Ability to do object count quota for all namespaced resources **What this PR does / why we need it**: - Defines syntax for generic object count quota `count/<resource>.<group>` - Migrates existing objects to support new syntax with old syntax - Adds support to quota all standard namespace resources - Updates the controller to do discovery and replenishment on those resources - Updates unit tests - Tweaks admission configuration around quota - Add e2e test for replicasets (demonstrate dynamic generic counting) ``` $ kubectl create quota test --hard=count/deployments.extensions=2,count/replicasets.extensions=4,count/pods=3,count/secrets=4 resourcequota "test" created $ kubectl run nginx --image=nginx --replicas=2 $ kubectl describe quota Name: test Namespace: default Resource Used Hard -------- ---- ---- count/deployments.extensions 1 2 count/pods 2 3 count/replicasets.extensions 1 4 count/secrets 1 4 ``` **Special notes for your reviewer**: - simple object count quotas no longer require writing code - deferring support for custom resources pending investigation about how to share caches with garbage collector. in addition, i would like to see how this integrates with downstream quota usage in openshift. **Release note**: ```release-note Object count quotas supported on all standard resources using `count/<resource>.<group>` syntax ``` |

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.
