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>. Report InstanceID for vSphere Cloud Provider as UUID obtained from product_serial file **What this PR does / why we need it**: vSphere Cloud Provider is not able to find the nodes for VMs created on vSphere v1.6.5. Kubelet fetches SystemUUID from file ```/sys/class/dmi/id/product_uuid```. vSphere Cloud Provider uses this uuid as VM identifier to get node information from vCenter. vCenter v1.6.5 doesn't recognize this uuids, as a result, nodes are not found. UUID present in file ```/sys/class/dmi/id/product_serial``` is recognized by vCenter. Yet, Kubelet doesn't report this. Therefore, in this PR InstanceID is reported as UUID which is fetched from file ```/sys/class/dmi/id/product_serial```. **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 https://github.com/kubernetes/kubernetes/issues/58927 **Special notes for your reviewer**: Internally review here: https://github.com/vmware/kubernetes/pull/452 Tested: Launched K8s cluster using kubeadm (Used Ubuntu VM compatible with vSphere version 6.5.) _**Note: Installed Ubuntu from ISO**_ Observed following: ``` Master > cat /sys/class/dmi/id/product_uuid 743F0E42-84EA-A2F9-7736-6106BB5DBF6B > cat /sys/class/dmi/id/product_serial VMware-42 0e 3f 74 ea 84 f9 a2-77 36 61 06 bb 5d bf 6b Node > cat /sys/class/dmi/id/product_uuid 956E0E42-CC9D-3D89-9757-F27CEB539B76 > cat /sys/class/dmi/id/product_serial VMware-42 0e 6e 95 9d cc 89 3d-97 57 f2 7c eb 53 9b 76 ``` With this fix controller manager was able to find the nodes. **controller manager logs** ``` {"log":"I0205 22:43:00.106416 1 nodemanager.go:183] Found node ubuntu-node as vm=VirtualMachine:vm-95 in vc=10.161.120.115 and datacenter=vcqaDC\n","stream":"stderr","time":"2018-02-05T22:43:00.421010375Z"} ``` **Release note**: ```release-note vSphere Cloud Provider supports VMs provisioned on vSphere v1.6.5 ``` |

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.
