Automatic merge from submit-queue (batch tested with PRs 57824, 58806, 59410, 59280). 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>. 2nd try at using a vanity GCR name The 2nd commit here is the changes relative to the reverted PR. Please focus review attention on that. This is the 2nd attempt. The previous try (#57573) was reverted while we figured out the regional mirrors (oops). New plan: k8s.gcr.io is a read-only facade that auto-detects your source region (us, eu, or asia for now) and pulls from the closest. To publish an image, push k8s-staging.gcr.io and it will be synced to the regionals automatically (similar to today). For now the staging is an alias to gcr.io/google_containers (the legacy URL). When we move off of google-owned projects (working on it), then we just do a one-time sync, and change the google-internal config, and nobody outside should notice. We can, in parallel, change the auto-sync into a manual sync - send a PR to "promote" something from staging, and a bot activates it. Nice and visible, easy to keep track of. xref https://github.com/kubernetes/release/issues/281 TL;DR: * The new `staging-k8s.gcr.io` is where we push images. It is literally an alias to `gcr.io/google_containers` (the existing repo) and is hosted in the US. * The contents of `staging-k8s.gcr.io` are automatically synced to `{asia,eu,us)-k8s.gcr.io`. * The new `k8s.gcr.io` will be a read-only alias to whichever regional repo is closest to you. * In the future, images will be promoted from `staging` to regional "prod" more explicitly and auditably. ```release-note Use "k8s.gcr.io" for pulling container images rather than "gcr.io/google_containers". Images are already synced, so this should not impact anyone materially. Documentation and tools should all convert to the new name. Users should take note of this in case they see this new name in the system. ``` |

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
For the full story, 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.
