Automatic merge from submit-queue (batch tested with PRs 61482, 61740). 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>. Make systemd service name for kubelet use a timestamp in e2e-node tests. **What this PR does / why we need it**: This makes it easier to figure out which execution was last when looking at the output of `systemd list-units kubelet-*.service`. We try to find the name of the /tmp/node-e2e-* directory and use the same timestamp if we can. Otherwise, we just call Now() again, which isn't as nice (as the unit name and directory name will not match) but will still produce unit names that will be ordered when launching multiple subsequent executions on the same host. **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: N/A **Special notes for your reviewer**: Tested using `make test-e2e-node REMOTE=true` and then checking `systemctl list-units kubelet-*.service` on the target host. ``` $ systemctl list-units kubelet-*.service kubelet-20180326T142016.service loaded active exited /tmp/node-e2e-20180326T142016/kubelet --kubeconfig /tmp/node-e2e-20180326T142016/kubeconfig --root-dir /var/lib/kubelet ... kubelet-20180326T143550.service loaded active exited /tmp/node-e2e-20180326T143550/kubelet --kubeconfig /tmp/node-e2e-20180326T143550/kubeconfig --root-dir /var/lib/kubelet ... ``` The units are sorted in the order they were launched. **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.
