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>. Display extended resources in node allocated resources **What this PR does / why we need it**: Displays ~~opaque integer~~ [extended] resources in node allocated resources of command `kubectl describe node`. This will give users more info about node ~~OIR~~ [extended resources] consumption. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes # This is a partially fix of #44271. **Special notes for your reviewer**: This PR - only displays allocated ~~OIR~~ [extended resources] details of node, it doesn't display ~~OIR~~ [extended resources] requests/limits for each pod because it's hard to organize format. I tried to print ~~OIR~~ [extended resources] requests/limits of pods, but some strings have been eaten when a line is too long (the output has been separated into two lines by terminal). I think it's because a `\t` blank can't be show in two lines. - ~~uses `OIR-foo` instead of `pod.alpha.kubernetes.io/opaque-int-resource-foo` for short.~~ - doesn't display the percentage of ~~OIR~~ [extended resources] usage because I think the percentage is not so meaningful. - displays each ~~OIR~~ [extended resources] in single rows to be clear. UPDATE: Example with default namespace resource: ``` Non-terminated Pods: (1 in total) Namespace Name CPU Requests CPU Limits Memory Requests Memory Limits --------- ---- ------------ ---------- --------------- ------------- default rc-nginx-single-krp84 1 (33%) 1 (33%) 512Mi (6%) 512Mi (6%) Allocated resources: (Total limits may be over 100 percent, i.e., overcommitted.) Resource Requests Limits -------- -------- ------ cpu 1 (33%) 1 (33%) memory 512Mi (6%) 512Mi (6%) kubernetes.io/widgets 111 0 ``` /cc @ConnorDoyle @soltysh ref #44181 **Release note**: ```release-note Display requests/limits of extended resources in node allocated resources. ``` |

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.
