Automatic merge from submit-queue (batch tested with PRs 46383, 45645, 45923, 44884, 46294) Node status updater now deletes the node entry in attach updates... … when node is missing in NodeInformer cache. - Added RemoveNodeFromAttachUpdates as part of node status updater operations. **What this PR does / why we need it**: Fixes issue of unnecessary node status updates when node is deleted. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #42438 **Special notes for your reviewer**: Unit tested added, but a more comprehensive test involving the attach detach controller requires certain testing functionality that is currently absent, and will require larger effort. Will be added at a later time. There is an edge case caused by the following steps: 1) A node is deleted and restarted. The node exists, but is not yet recognized by Kubernetes. 2) A pod requiring a volume attach with nodeName specifically set to this node. This would make the pod stuck in ContainerCreating state. This is low-pri since it's a specific edge case that can be avoided. **Release note**: ```release-note NONE ``` |

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.
