Yes, it is possible to cluster the raspberry py, I remember one demo in which one guy at rancher labs create a hybrid cluster using k3s nodes running on Linux VMs and physical raspberry py. Same reason it's not great for very large services that occupy an entire node without modifying setup from default. I had heard k3s was an option, but I can’t find an example for k3s that puts multiple nodes on one machine. You switched accounts on another tab or window.
