Automatic merge from submit-queue Let the quota evaluator handle mutating specs of pod & pvc ### Background The final goal is to address https://github.com/kubernetes/kubernetes/issues/47837, which aims to allow more mutation for uninitialized objects. To do that, we [decided](https://github.com/kubernetes/kubernetes/issues/47837#issuecomment-321462433) to let the admission controllers to handle mutation of uninitialized objects. ### Issue #50399 attempted to fix all admission controllers so that can handle mutating uninitialized objects. It was incomplete. I didn't realize although the resourcequota admission plugin handles the update operation, the underlying evaluator didn't. This PR updated the evaluators to handle updates of uninitialized pods/pvc. ### TODO We still miss another piece. The [quota replenish controller](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/resourcequota/replenishment_controller.go) uses the sharedinformer, which doesn't observe the deletion of uninitialized pods at the moment. So there is a quota leak if a pod is deleted before it's initialized. It will be addressed with https://github.com/kubernetes/kubernetes/issues/48893. |

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.
