Automatic merge from submit-queue (batch tested with PRs 44337, 45775, 45832, 45574, 45758) Tighten validation of mirror pod annotations Tightens validation for pods with a mirror pod annotation: 1. spec.nodeName must be set 2. makes the mirror pod annotation immutable 3. starts validating pod-specific annotations during pod status update None of these changes affect usage of the mirror pod annotation by kubelets, which only set it on pod creation (verified this is true back to 1.5.x) the second commit updates the pod validation tests to look for specific error messages (best reviewed ignoring whitespace changes) This is the validation portion of https://github.com/kubernetes/community/blob/master/contributors/design-proposals/kubelet-authorizer.md and https://github.com/kubernetes/features/issues/279 ```release-note Mirror pods must now indicate the nodeName they are bound to on creation. The mirror pod annotation is now treated as immutable and cannot be added to an existing pod, removed from a pod, or modified. ``` |

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.
