Automatic merge from submit-queue (batch tested with PRs 50953, 51082) Fix mergekey of initializers; Repair invalid update of initializers Fix https://github.com/kubernetes/kubernetes/issues/51131 The PR did two things to make parallel patching `metadata.initializers.pending` possible: * Add mergekey to initializers.pending * Let the initializer admission plugin set the `metadata.intializers` to nil if an update makes the `pending` and the `result` both nil, instead of returning a validation error. Otherwise if multiple initializer controllers sending the patch removing themselves from `pending` at the same time, one of them will get a validation error. ```release-note The patch to remove the last initializer from metadata.initializer.pending will result in metadata.initializer to be set to nil (assuming metadata.initializer.result is also nil), instead of resulting in an validation error. ``` |

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.
