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>. kubeadm: Drop arch suffixes **What this PR does / why we need it**: This change removes arch suffixes from control plane images (etcd, kube-apiserver, kube-scheduler, kube-proxy, etc.). These are not needed, as almost all control plane images have a fat manifest now. It also adds a missing unit test for `GetGenericImage` We have arch suffixes only for kube-dns images now. Sample output of `kubeadm config images pull` with this change: ``` $ ./_output/bin/kubeadm config images pull [config/images] Pulled k8s.gcr.io/kube-apiserver:v1.11.1 [config/images] Pulled k8s.gcr.io/kube-controller-manager:v1.11.1 [config/images] Pulled k8s.gcr.io/kube-scheduler:v1.11.1 [config/images] Pulled k8s.gcr.io/kube-proxy:v1.11.1 [config/images] Pulled k8s.gcr.io/pause:3.1 [config/images] Pulled k8s.gcr.io/etcd:3.2.18 [config/images] Pulled k8s.gcr.io/coredns:1.1.3 $ ./_output/bin/kubeadm config images pull --feature-gates=CoreDNS=false [config/images] Pulled k8s.gcr.io/kube-apiserver:v1.11.1 [config/images] Pulled k8s.gcr.io/kube-controller-manager:v1.11.1 [config/images] Pulled k8s.gcr.io/kube-scheduler:v1.11.1 [config/images] Pulled k8s.gcr.io/kube-proxy:v1.11.1 [config/images] Pulled k8s.gcr.io/pause:3.1 [config/images] Pulled k8s.gcr.io/etcd:3.2.18 [config/images] Pulled k8s.gcr.io/k8s-dns-kube-dns-amd64:1.14.10 [config/images] Pulled k8s.gcr.io/k8s-dns-sidecar-amd64:1.14.10 [config/images] Pulled k8s.gcr.io/k8s-dns-dnsmasq-nanny-amd64:1.14.10 ``` **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Refs kubernetes/kubeadm#1030 kubernetes/kubeadm#51 **Special notes for your reviewer**: /cc @kubernetes/sig-cluster-lifecycle-pr-reviews /area kubeadm /kind feature /assign @luxas /assign @timothysc /assign @dims /assign @neolit123 **Release note**: ```release-note kubeadm: Control plane images (etcd, kube-apiserver, kube-proxy, etc.) don't use arch suffixes.

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.
