Automatic merge from submit-queue (batch tested with PRs 50555, 51152). 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>. Implement CRI stats in Docker Shim **What this PR does / why we need it**: This PR implements CRI Stats in the Docker Shim. It is needed to enable CRI stats for Docker and ongoing /stats/summary API changes in moving to use CRI. Related issues: #46984 (CRI: instruct kubelet to (optionally) consume container stats from CRI) #45614 (CRI: add methods for container stats) This PR is also a followup to my original PR (https://github.com/kubernetes/kubernetes/pull/50396) to implement Windows Container Stats. The plan is that Windows Stats will use a hybrid model: pod and container level stats will come from CRI (via dockershim) and that node level stats will come from a "winstats" package that exports cadvisor like datastructures using windows specific perf counters from the node. I will update that PR to only export node level stats. @yujuhong @yguo0905 @dchen1107 @jdumars @anhowe @michmike **Special notes for your reviewer**: **Release note**: ```release-note ``` |

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.
