Kubernetes ported to ARM boards like Raspberry Pi.
This release is a complete reboot compared to earlier releases. Now, docker-multinode is used as the base, along with the official flannel, hyperkube, dashboard and kube-dns docker images. I've added arm, arm64 and ppc64le variants for the most important Kubernetes images, so now Kubernetes releases all binaries and images automatically in their release process.
Everything is written in line with my multi-platform proposal: https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/multi-platform.md
It's also possible to setup Kubernetes on ARM on Pine64 easily with the deb package!
Supported boards/OSes:
amd64, no more releasing from Raspberry Pis!amd64 nodes seamlessly with docker-multinode
beta.kubernetes.io/arch label: kubernetes/kubernetes#23684
skydns component has been replaced with the new kubedns component that is more integrated with Kubernetes and more efficent.kube-config and of the whole project; as much as possible official Kubernetes code is used, which means the configuration for v0.8.0 is more generic than v0.7.0 which was more specialized.localhost:5000
--containerized by adding export USE_CONTAINERIZED=true to /etc/kubernetes/k8s.conf
kube-systemd to docker-multinode and the generic systemd OS to the generic debian OSdocker pull mtu bug docker/docker#22635

I'm gonna continue to work hard on making this project unnecessary!
A lot of new features are in the largest release of Kubernetes on ARM yet made. Highlights include officially built Kubernetes v1.2.0 ARM binaries, much better performance and cluster insight via the heapster addon.
