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>. Support containerized kubelet in CI **What this PR does / why we need it**: * Adjust hyperkube Makefile to allow HYPERKUBE_BIN to be specified from outside * new DOCKER_ROOT variable to specify --root-dir and associated volume for kubelet to know where docker directory lives * Save the docker logs when we kill the kubelet container * Allow customized image for dockerized kubelet and build a Default image if one is not specified We should allow a custom build using script we have: `VERSION="latest" REGISTRY="k8s.gcr.io" hack/dev-push-hyperkube.sh` to be used quickly using DOCKERIZE_KUBELET. To do this we remove the hard coded `k8s.gcr.io/kubelet` image and introduce a new environment variable `KUBELET_IMAGE`. Note that we are switching to hyperkube from kubelet as we have a quick and easy script to build hyperkube image and load it into local docker daemon. This reduces bad hacks like `docker tag k8s.gcr.io/hyperkube-amd64:<tag> k8s.gcr.io/kubelet:latest` being used by folks today (see 62057) * Better cope with PID 0 when running "docker inspect" to look for the process id for kubelet container **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes # **Special notes for your reviewer**: **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
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.
