The Continuing Saga of Running Kubernetes on RPi 3 B+ Cluster

So when I said I had Kubernetes running on a four node Raspberry Pi 3 B+ cluster,  I didn’t realize how complex a task it would turn out to be!

I had been following the instructions by Alex Ellis, but it turns out the latest version of Docker and Kubernetes doesn’t run well on the RPi 3 B+. I had to downgrade them to previous versions.

Then there were issues with the network stack. I tried Weave as recommended by Alex, but that didn’t work, so I switched to Flannel. I was then able to get the markdown to HTML converter example running. However, when I went to try setting up a dashboard I couldn’t get that to run because of issues with Flannel. Maybe I’ll try Calico next?

As for the hardware, I’ve added three more Pi’s to make a seven node cluster (one master and six workers).

I’ll have to spend some more time search google and reading documentation to figure this one out.
