Automatic merge from submit-queue Filter out IPV6 addresses from NodeAddresses() returned by vSphere The vSphere CP returns both IPV6 and IPV4 addresses for a Node as part of NodeAddresses() implementation. However, Kubelet fails due to duplicate api.NodeAddress value when the node has an IPV6 address associated with it. This issue is tracked in #42690. The following are observed: - when we enabled the logs and checked the addresses sent by vSphere CP to Kubelet, we don't see any duplicate addresses at all. - Also, kubelet_node_status doesn’t receive any duplicate address from cloud provider. However, when we filter out the IPV6 addresses and only return IPV4 addresses to the Kubelet, it works perfectly fine. Even though the Kubelet receives the non-duplicate node-addresses, it still errors out with duplicate node addresses. It might be an issue when kubelet propagates these addresses to API server (or) API server is enable to handle IPV6 addresses. @divyenpatel @abrarshivani @pdhamdhere @tusharnt **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
If you are less impatient, 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.
