Add DynamicProvisioningScheduling support for EBS **What this PR does / why we need it**: This PR adds support for the DynamicProvisioningScheduling feature in EBS. With this in place, if VolumeBindingMode: WaitForFirstConsumer is specified in a EBS storageclass and DynamicProvisioningScheduling is enabled, EBS provisioner will use the selected node's LabelZoneFailureDomain as the zone to provision the EBS volume in. **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes # **Special notes for your reviewer**: Related to #63232 Sample `describe pv` output with NodeAffinity populated: ``` ~$ kubectl describe pv pvc-f9d2138b-7e3e-11e8-a4ea-064124617820 Name: pvc-f9d2138b-7e3e-11e8-a4ea-064124617820 Labels: failure-domain.beta.kubernetes.io/region=us-west-2 failure-domain.beta.kubernetes.io/zone=us-west-2a Annotations: kubernetes.io/createdby=aws-ebs-dynamic-provisioner pv.kubernetes.io/bound-by-controller=yes pv.kubernetes.io/provisioned-by=kubernetes.io/aws-ebs Finalizers: [kubernetes.io/pv-protection] StorageClass: slow3 Status: Bound Claim: default/pvc3 Reclaim Policy: Delete Access Modes: RWO Capacity: 6Gi Node Affinity: Required Terms: Term 0: failure-domain.beta.kubernetes.io/zone in [us-west-2a] failure-domain.beta.kubernetes.io/region in [us-west-2] Message: Source: Type: AWSElasticBlockStore (a Persistent Disk resource in AWS) VolumeID: aws://us-west-2a/vol-0fc1cdae7d10860f6 FSType: ext4 Partition: 0 ReadOnly: false Events: <none> ``` **Release note**: ```release-note none ``` /sig storage /assign @msau42 @jsafrane |

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.
