Automatic merge from submit-queue Add --feature-gate flags to kubeadm **What this PR does / why we need it**: Adds `--feature-gates` in similar manner to other `cmd` binaries **Which issue this PR fixes** https://github.com/kubernetes/kubeadm/issues/323 **Special notes for your reviewer**: This results in a lot of probably unnecessary feature flags. I'm guessing a lot of kubeadm users will be confused when they see: ``` Flags: --feature-gates mapStringBool A set of key=value pairs that describe feature gates for alpha/experimental features. Options are: APIResponseCompression=true|false (ALPHA - default=false) Accelerators=true|false (ALPHA - default=false) AdvancedAuditing=true|false (ALPHA - default=false) AllAlpha=true|false (ALPHA - default=false) AllowExtTrafficLocalEndpoints=true|false (default=true) AppArmor=true|false (BETA - default=true) DebugContainers=true|false (ALPHA - default=false) DynamicKubeletConfig=true|false (ALPHA - default=false) DynamicVolumeProvisioning=true|false (ALPHA - default=true) ExperimentalCriticalPodAnnotation=true|false (ALPHA - default=false) ExperimentalHostUserNamespaceDefaulting=true|false (BETA - default=false) LocalStorageCapacityIsolation=true|false (ALPHA - default=false) PersistentLocalVolumes=true|false (ALPHA - default=false) PodPriority=true|false (ALPHA - default=false) RotateKubeletClientCertificate=true|false (ALPHA - default=false) RotateKubeletServerCertificate=true|false (ALPHA - default=false) StreamingProxyRedirects=true|false (BETA - default=true) TaintBasedEvictions=true|false (ALPHA - default=false) -h, --help help for kubeadm ``` However the feature flags used in the core pkg is global, so I don't think it can be overriden. So we have a few options: 1. Allow these flags for kubeadm 2. Refactor feature pkg to allow granular features 3. Roll our own feature gating for kubeadm /cc @luxas |

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.
