Automatic merge from submit-queue. If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Remove old featureGate flag in Readme **What this PR does / why we need it**: This PR corrects the Readme for ipvs mode: https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/ipvs/README.md. `kubeadm init` doesn't support the `--feature-gates=SupportIPVSProxyMode=true` flag anymore since IPVS is in beta and not alpha anymore. ``` sudo kubeadm init --help Run this command in order to set up the Kubernetes master. Usage: kubeadm init [flags] Flags: --apiserver-advertise-address string The IP address the API Server will advertise it's listening on. Specify '0.0.0.0' to use the address of the default network interface. --apiserver-bind-port int32 Port for the API Server to bind to. (default 6443) --apiserver-cert-extra-sans stringSlice Optional extra Subject Alternative Names (SANs) to use for the API Server serving certificate. Can be both IP addresses and DNS names. --cert-dir string The path where to save and store the certificates. (default "/etc/kubernetes/pki") --config string Path to kubeadm config file. WARNING: Usage of a configuration file is experimental. --cri-socket string Specify the CRI socket to connect to. (default "/var/run/dockershim.sock") --dry-run Don't apply any changes; just output what would be done. --feature-gates string A set of key=value pairs that describe feature gates for various features. Options are: CoreDNS=true|false (ALPHA - default=false) DynamicKubeletConfig=true|false (ALPHA - default=false) SelfHosting=true|false (ALPHA - default=false) StoreCertsInSecrets=true|false (ALPHA - default=false) --ignore-preflight-errors stringSlice A list of checks whose errors will be shown as warnings. Example: 'IsPrivilegedUser,Swap'. Value 'all' ignores errors from all checks. --kubernetes-version string Choose a specific Kubernetes version for the control plane. (default "stable-1.9") --node-name string Specify the node name. --pod-network-cidr string Specify range of IP addresses for the pod network. If set, the control plane will automatically allocate CIDRs for every node. --service-cidr string Use alternative range of IP address for service VIPs. (default "10.96.0.0/12") --service-dns-domain string Use alternative domain for services, e.g. "myorg.internal". (default "cluster.local") --skip-token-print Skip printing of the default bootstrap token generated by 'kubeadm init'. --token string The token to use for establishing bidirectional trust between nodes and masters. --token-ttl duration The duration before the bootstrap token is automatically deleted. If set to '0', the token will never expire. (default 24h0m0s) ``` **Special notes for your reviewer**: Used kubeadm version: ```bash sudo kubeadm version kubeadm version: &version.Info{Major:"1", Minor:"9", GitVersion:"v1.9.3", GitCommit:"d2835416544f298c919e2ead3be3d0864b52323b", GitTreeState:"clean", BuildDate:"2018-02-07T11:55:20Z", GoVersion:"go1.9.2", Compiler:"gc", Platform:"linux/amd64"} ``` **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
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.
