Simplify device manager: make endpoint stateless While reviewing devicemanager code, found the caching layer on endpoint is redundant. Here are the 3 related objects in picture: **devicemanager <-> endpoint <-> plugin** plugin is the source of truth for devices and device health status. devicemanager maintain healthyDevices, unhealthyDevices, allocatedDevices based on updates from plugin. So there is no point for endpoint to cache devices, this patch is removing the cache layer, endpoint becomes stateless, which i believe should be the case (but i do welcome review if i missed something here). also removing the Manager.Devices() since i didn't find any caller of this other than test. if we need to get all devices from manager in future, it just need to return healthyDevices + unhealthyDevices, so don't have to call endpoint after all. This patch makes code more readable, data model been simplified. **What this PR does / why we need it**: this patch simplify the device manager code, make it more maintainable. **Which issue(s) this PR fixes** *: this is a refactor of device manager code **Special notes for your reviewer**: will need to rebase the code if #58755 get checked-in first. **Release note**: ```release-note None ``` /sig node /cc @jiayingz @RenaudWasTaken @vishh @saad-ali @vikaschoudhary16 @vladimirvivien @anfernee
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.
