Automatic merge from submit-queue (batch tested with PRs 46686, 45049, 46323, 45708, 46487) [Federation][kubefed]: Use StorageClassName for etcd pvc This PR updates kubefed to use the StorageClassName field [added in 1.6](http://blog.kubernetes.io/2017/03/dynamic-provisioning-and-storage-classes-kubernetes.html ) for etcd's pvc to allow the user to specify which storage class they want to use. If no value is provided to ``kubefed init``, the field will not be set, and initialization of the pvc may fail on a cluster without a default storage class configured. The alpha annotation that was previously used (``volume.alpha.kubernetes.io/storage-class``) was deprecated as of 1.4 according to the following blog post: http://blog.kubernetes.io/2016/10/dynamic-provisioning-and-storage-in-kubernetes.html **Release note**: ``` 'kubefed init' has been updated to support specification of the storage class (via --etcd-pv-storage-class) for the Persistent Volume Claim (PVC) used for etcd storage. If --etcd-pv-storage-class is not specified, the default storage class configured for the cluster will be used. ``` cc: @kubernetes/sig-federation-pr-reviews
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.
