Automatic merge from submit-queue (batch tested with PRs 54230, 58100, 57861, 54752). 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>. GCE: Use existing subnetwork of ILB forwarding rule Fixes #57860 **Test Cases**: Clusters using auto network with existence of a manual subnet in same region. - [x] Upgrade 1.7 cluster with existing ILBs to latest. Confirm existing ILBs still are synced. Version 1.7 does not attempt to fill in the subnetwork, so the forwarding rule was created with the correct subnetwork. - [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using wrong subnet) still are synced. - [x] Latest version creates ILBs using the correct subnet. Clusters with manual subnets have always and will continue to use the subnet specified in gce.conf. - [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using manual subnet) still are synced. Clusters with legacy networks have always and will continue to use an empty subnet. - [x] Upgrade 1.8 cluster with existing ILBs to latest. Confirm existing ILBs (using legacy network) still are synced. **Release note**: ```release-note GCE: Allows existing internal load balancers to continue using an outdated subnetwork ``` |

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.
