Automatic merge from submit-queue (batch tested with PRs 51471, 50561, 50435, 51473, 51436) Feature gate initializers field The metadata.initializers field should be feature gated and disabled by default while in alpha, especially since enforcement of initializer permission that keeps users from submitting objects with their own initializers specified is done via an admission plugin most clusters do not enable yet. Not gating the field and tests caused tests added in https://github.com/kubernetes/kubernetes/issues/51429 to fail on clusters that don't enable the admission plugin. This PR: * adds an `Initializers` feature gate, auto-enables the feature gate if the admission plugin is enabled * clears the `metadata.initializers` field of objects on create/update if the feature gate is not set * marks the e2e tests as feature-dependent (will follow up with PR to test-infra to enable the feature and opt in for GCE e2e tests) ```release-note Use of the alpha initializers feature now requires enabling the `Initializers` feature gate. This feature gate is auto-enabled if the `Initialzers` admission plugin is enabled. ``` |

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.
