The Kuberdoo is a mini desktop computer cluster. It consists of 6 UDOO X86 boards, router, switch, power supply, and custom built acrylic case. The goal of the project is a desktop platform for testing bare-metal multi-machine technologies that are otherwise difficult or impossible to do with Virtual Machines.
I recently finished this build but just learned about hackaday.io so I did not get to log information about it. So, consider this the start of the post-project (gathering the materials, instructions, CAD files) :)
Cool! If you used the drawings in GitHub there are some tweaks you'll need to do to make things fit right. I'll try to flesh out more of the networking bootstrap and usage instructions this weekend for you.
I was thing using something like theforeman.org or http://cobbler.github.io to provision the nodes. Not sure how are you using the router(network segmentation?). Also, the router PSU is 24V. Is it working ok with 12v?
Yes, the Mikrotik hEX has a wide input voltage (usually for PoE). It runs on 8-30V DC. Also, if you check out https://github.com/andyshinn/kuberdoo/tree/master/config I have some example config files for the Mikrotik to do PXE booting using Ubuntu preseed methods. I've also successfully used one of the UDDO boards to be a Ubuntu MAAS server to handle the provisioning of the other 5.
Awesome design. Think it's great and I already proposed to use this project as a blueprint for our company's own x86 Kubernetes cluster in our testlab.
:( I'm sorry you don't like the look much. I wanted something where I could view the internals because I like to see my electronics. But I suppose it could also be cut out of opaque acrylic as well.
The cooling slots with single fan is actually very efficient. I did disk and CPU stress tests on all the boards simultaneously and the temperatures stayed just over 50c per board, which is much better than most report with the stock heatsink and single fan!
Great project. I already ordered the acrylic based on your onsite drawings.
Question: more details about the network?
