Automatic merge from submit-queue. 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>. Make UnstructuredContent return contents without mutating the source **What this PR does / why we need it**: This PR solves the issues described in #56316 Before this change: - A call to `UnstructuredContent()` potentially modified `Object` - The values returned by `UnstructuredContent()` could be manipulated to modify the value in `Object`. Going through the history it looks like this behavior was added before the addition of `SetUnstructuredContent()`. IMO it makes more sense now to use `SetUnstructuredContent()` or make changes to the exposed `Object` property - `UnstructuredList` did not implement the behavior described in the godoc. The godoc stated that the value returned should be mutable, but if u.Object == nil the map returned had no effect on Object With this PR I'm proposing `UnstructuredContent()` returns the data without providing the contract of a mutable map. It also ensures all implementations of the `Unstructured` interface abide by the doc **Which issue(s) this PR fixes**: Fixes #56316 **Special notes for your reviewer**: This PR continues work started in #57713. **Release note**: ```release-note NONE ``` /kind bug /sig api-machinery /cc sttts deads2k |

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.
