Automatic merge from submit-queue (batch tested with PRs 58690, 64773, 64880, 64915, 64831). 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>. apimachinery: unify accessors to not deepcopy The Get/SetOwnerReferences accessor funcs do deepcopies, in contrast to all other accessor funcs of metav1.ObjectMeta. For unstructured.Unstructured we naturally do deepcopies. In other words: the interface does guarantee neither the first nor the second. This PR documents this and remove the unneccessary deepcopy for owner references (which leads to huge heap allocation e.g. in the DaemonSet controller). This is for post-1.11. **do not assign a milestone**. ```dev-release-note The metav1.ObjectMeta accessor does not deepcopy owner references anymore. In general, the accessor interface does not enforce deepcopy nor does it forbid it (e.g. for unstructured.Unstructured). ``` |

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.
