A Rational Approach to Raspberry Pi Clustering

clem57

I was browsing the net like millions of at home people, when this caught my eye. It talks about reasons for clustering raspberry pi  instead of tutorial approach. https://ubuntu.com/blog/building-a-raspberry-pi-cluster-with-microk8s is unique way in my opinion. Please add your thoughts. Is the software good? Have you tried to cluster a raspberry pi? Any good use cases?

  • Hello Clem,

     

    Kubernetes is the best, the fast, the powerful. So by my own nature, I am suspicious. Then I investigate. Then definitely I think – it is my personal vision – That it is too much too too too ... Why?

     

    First of all, because it is open-source but the version for the Pi is a sort of reduced setting than the most powerful K8 installation that born and has been conceived to run on big machines and there it works best. I think that as the Pi in a reduced but not wrong vision is a Linux machine, you can also use if to run a virtualization server, but if you want a flexible and manageable system, this is not the right way. Different if you want to experiment.

    Second, it runs only on Ubuntu, that it is an incredible – and under some points of view unacceptable – approach for a Linux Open Source project.

     

    These two factors are sufficient to decide to find a more comfortable way, more tailored to work with the Raspberry Pi, and also easy to set-up and configure based on the needs. Many of the K8 features are not viable or has a very few sense to run on the Pi for a lot of reasons. So, I have built one following a different approach; I make a four nodes PiCluster machine that I can use in my real everyday work, with the needs a common user can solve. The setting may be a bit more complex, but there are more Pi-oriented options that give the possibility to configure the cluster just to do the right job. At an inexpensive cost.

     

    You can find more in the details on this how-to (catched here and there on the net, trying to focus the point I wrote above).
