Automatic merge from submit-queue (batch tested with PRs 63137, 62913). 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 a simple dynamic client that is easy to use The dynamic client has annoyed me for the last time! The existing one takes arguments at odd levels, requires lots of information to instantiate, does some weird pool thing, and uses unusual types. This creates an interface like this: ```go type DynamicInterface interface { ClusterResource(resource schema.GroupVersionResource) DynamicResourceInterface NamespacedResource(resource schema.GroupVersionResource, namespace string) DynamicResourceInterface } type DynamicResourceInterface interface { Create(obj *unstructured.Unstructured) (*unstructured.Unstructured, error) Update(obj *unstructured.Unstructured) (*unstructured.Unstructured, error) UpdateStatus(obj *unstructured.Unstructured) (*unstructured.Unstructured, error) Delete(name string, options *metav1.DeleteOptions) error DeleteCollection(options *metav1.DeleteOptions, listOptions metav1.ListOptions) error Get(name string, options metav1.GetOptions) (*unstructured.Unstructured, error) List(opts metav1.ListOptions) (*unstructured.UnstructuredList, error) Watch(opts metav1.ListOptions) (watch.Interface, error) Patch(name string, pt types.PatchType, data []byte, subresources ...string) (*unstructured.Unstructured, error) } ``` You create it from just a `rest.Config`, no mapper, no path resolving func, no trying to set up codecs ahead of time, no unnecessary pool. It just works. I updated the namespace controller to use it and I updated the existing dynamic client to leverage it so that I get all their tests for "free". @kubernetes/sig-api-machinery-pr-reviews @liggitt @smarterclayton @bparees @sttts @ironcladlou I know each of us has struggled with the dynamic client in our time. @lavalamp @caesarxuchao This is vastly simplifying. I'm eager to drop the old `ClientPool`. client-go will technically have another incompatible semver this release. I'm up for changing it in tree. ```release-note client-go developers: the new dynamic client is easier to use and the old is deprecated, you must switch. ``` |

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.
