What does everyone else run on their cluster?

[Ben Heininger]

What is everyone else using their cluster for?
Just trying to get other ideas as to what I can do with my cluster.

I got Docker swarm running mine and have used it to learn the basics of Ansible.
I wanted to learn Kubernetes but couldnt get it running since I only had RPi Zero 1.3s
Now that they are available I have some RPi Zero 2Ws on order to replace the 1.3s.

I would like to learn more about how the RPI Zero 2Ws work in your Cluster Hat.  I want to upgrade mine.

My Cluster hat got expanded. It now includes the following:

Four Pi Zeros            -- Raspbian

One Pi 3b+                -- Raspbian (Controller)

Four Pi 3b+               -- Hypriot OS   -- I Could add another four quite easily. Only cash flow is the limiting factor.

One Banana Pi Pro  --  Armbian

While they all run Docker Swarm, I have them processing university data for 4 BOINC projects.

This eclectic little cluster has been running for years, (Four plus?)  now almost non-stop.

Michael, 

Thank you, that's interesting work.

Tom,

I tried transferring the sd card from the zero 1.3 to the zero 2w and it worked. The only downside was that it was still only 32 bit os. 

I downloaded the 64bit image for RPi1 and re-imaged the sd card, plugged it all back together and it fired up fine. I don't have any further information as I haven't found a valuable use for it yet.

Hopefully when I have 4x RPi Zero 2ws I can try Kubernetes again.

I also dont know what I can do with my original Zero 1.3s, maybe I need another clusterhat and another normal Pi?
