Hashicorp Nomad[0] is surprisingly simple yet powerful. It fits quite nicely between Swarm and Kubernetes/Mesos, as this project mentions. I'm not sure that it can run on the Raspberry Pi, but it is definitely worth a try. [0] https://www.nomadproject.io https://www.nomadproject.io

Worth mentioning "Raspberry" in the title.

  Good idea. However, PiCluster will work perfectly fine on regular x86 hardware.

    Oh! Then I misunderstood the github project. My bad.

Docker only, which is a shame.

  I can easily add another runtime. What were you thinking?

    Perhaps singularity?

    Thanks for the reply. Can you work with plain LXC/LCD?

      Right now, the server simply sends Docker engine commands to the agent nodes. If you know the equivilant commands for "docker build" and "Docker run", I should be able to add it

Nice! Takes 5 minutes to read through all code and all makes sense - and probably all works too. Kubernetes and nomad are a bear to get started with in comparison.

  The new kubeadm tool makes it a little easier, but I've always run into issues setting up networking. Truth be told though, I've found kubernetes fits in better as a piece of the orchestration puzzle rather than the end of it - I managed to get OpenShift (Origin) deployed in under 2 hours on 6 CentOS Atomic hosts (3 masters, 3 schedulable nodes) and got all the k8s goodness with a bunch of nice extras on top (same day we deployed 2 node.js apps to it and my team was super excited when I had them push to git, OpenShift automatically build and deployed the docker image and the new releases were live in moments). Seriously, if you want Kubernetes, look at just deploying openshift, there's ansible playbooks out there and even an installer to write the ansible inventory on your behalf to make it super easy, and the OpenVSwitch configuration is just magic compared to getting flannel set up right for k8s.

  After running my own k8s solution I discovered [1]. Kismatic makes a lot of the tasks to setup a cluster much easier. [1] https://github.com/apprenda/kismatic https://github.com/apprenda/kismatic
