Automatic merge from submit-queue kubeadm: Add node-cidr-mask-size to pass to kube-controller-manager for IPv6 Due to the increased size of subnets with IPv6, the node-cidr-mask-size needs to be passed to kube-controller-manager. If IPv4 it will be set to 24 as it was previously, if IPv6, it will be set to 64 **What this PR does / why we need it**: If the user specifies the --pod-network-cidr with kubeadm init, this caused the kube-controller-manager manifest to include the "--allocate-node-cidrs" and "--cluster-cidr" flags to be set. The --node-cidr-mask-size is not set, and currently defaults to 24, which is fine for IPv4, but not appropriate for IPv6. This change passes the a value as the node-cidr-mask-size to the controller-manager. It detects if it is IPv4 or v6, and sets --node-cidr-mask-size to 24 for IPv4 as before, and to 64 for IPv6. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #50469 **Special notes for your reviewer**: **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.
