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>. Restore pre-1.10 openstack instance naming behavior As noted in https://github.com/kubernetes/kubernetes/pull/61890#issuecomment-377282182 and https://github.com/kubernetes/kubernetes/issues/62295#issuecomment-389374492, the 1.10 changes to the openstack cloud provider node name computation (in #58502, #61000, and #61890) broke existing deployments that provisioned instances with credentials matching their instance names. It also did not account for version skewed kubelets, which can run 1.8 and 1.9 versions against a 1.10 master, and still register based on instance name. This PR reverts the incompatible changes to restore pre-1.10 behavior. Further improvements to handle instances with names that cannot be used as node names are tracked in https://github.com/kubernetes/kubernetes/issues/62295 /assign @dims /sig openstack /kind bug ```release-note Restores the pre-1.10 behavior of the openstack cloud provider which uses the instance name as the Kubernetes Node name. This requires instances be named with RFC-1123 compatible names. ``` |

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.
