Also check out Rancher. Lite weight K8 for distributed IoT. Scaling to 1000s of ARM nodes, clusters morph into incredibly smart supercomputing grids ;)

Unfortunately, none of the tech referenced in this articled is available yet and should be released end of February. There is a more interesting part that isn't referenced in this article and the is that we'll have two variants of k8s for ARM. One is RKE which is our CNCF certified k8s distribution. The other will be based off k3s (github.com/ibuildthecloud/k3s) which is an optimized k8s distribution for small clusters (smaller memory, easier setup, etc). I expected the second will be far more suited for something like this project.
