Can be more than just the latest kubeadm kept in the rpm repo?

Since kubeadm is still not a production ready tool, it would be great if we could go back to a kubeadm version which we know to work for us. When something like #212 happens, downgrading is very useful.

In kubevirt, we use kubeadm, to deploy kubernetes on our vagrant development- and CI-environment and it works great. I like using the latest version, and so also help finding possible new issues, but having the possibility to downgrade until something blocking is resolved, would be cool.

As far as I have seen, the old versions are still on the storage, they are just not referenced anymore. Could that be? We are using the CentoOS repo mentioned in the kubeadm getting started guide.

We used the following explicit verion urls to fall-back to the working version:

yum install -y http://yum.kubernetes.io/pool/082436e6e6cad1852864438b8f98ee6fa3b86b597554720b631876db39b8ef04-kubeadm-1.6.0-0.alpha.0.2074.a092d8e0f95f52.x86_64.rpm \
    http://yum.kubernetes.io/pool/2e63c1f9436c6413a4ea0f45145b97c6dbf55e9bb2a251adc38db1292bbd6ed1-kubelet-1.5.4-0.x86_64.rpm \
    http://yum.kubernetes.io/pool/fd9b1e2215cab6da7adc6e87e2710b91ecfda3b617edfe7e71c92277301a63ab-kubectl-1.5.4-0.x86_64.rpm \
    http://yum.kubernetes.io/pool/0c923b191423caccc65c550ef07ce61b97f991ad54785dab70dc07a5763f4222-kubernetes-cni-0.3.0.1-0.07a8a2.x86_64.rpm

(From kubevirt/kubevirt#179)

If the yum repository had contained these old versions, then it would have been much more easy to fallback.

Dupe of kubernetes/release#234. Hard to keep old versions but i'm documenting instructions here: kubernetes/website#3127
