If the dual-stack flag is enabled and the cluster is single stack IPv6, the allocator logic for service clusterIP does not properly handle rejecting a request for an IPv4 family. Return a 422 Invalid on the ipFamily field when the dual stack flag is on (as it would when it hits beta) and the cluster is configured for single-stack IPv6. The family is now defaulted or cleared in BeforeCreate/BeforeUpdate, and is either inherited from the previous object (if nil or unchanged), or set to the default strategy's family as necessary. The existing family defaulting when cluster ip is provided remains in the api section. We add additonal family defaulting at the time we allocate the IP to ensure that IPFamily is a consequence of the ClusterIP and prevent accidental reversion. This defaulting also ensures that old clients that submit a nil IPFamily for non ClusterIP services receive a default. To properly handle validation, make the strategy and the validation code path condition on which configuration options are passed to service storage. Move validation and preparation logic inside the strategy where it belongs. Service validation is now dependent on the configuration of the server, and as such ValidateConditionService needs to know what the allowed families are. |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts. It provides 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 your company 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 use Kubernetes code as a library in other applications, see the list of published components.
Use of the k8s.io/kubernetes module or k8s.io/kubernetes/... packages as libraries is not supported.
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.
mkdir -p $GOPATH/src/k8s.io
cd $GOPATH/src/k8s.io
git clone https://github.com/kubernetes/kubernetes
cd 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.
