While moving device_plugin_handler_test.go from pkg/kubelet/cm/ to pkg/kubelet/cm/deviceplugin/, we can no longer uses cm in its tests because that would cause a cycle dependency. To solve this problem, I moved the main cm GetResources functionality as well as part of the current device plugin handler Allocate functionality into a new device plugin handler function, GetDeviceRunContainerOptions(). This refactoring is also needed by another PR 51895 that moves device allocation into admission phase. Now device plugin handler Allocate() first checks whether there is cached device runtime state and only issues Allocate grpc call if there is no cached state available. The new GetDeviceRunContainerOptions() function simply returns device runtime config from the cached state. To support this change, extended the podDevices struct and checkpoint data structure with device runtime state. |

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.
