A pretty minimal K3s setup deployed on 2 RPi4 nodes. I couldn't continue with this setup because: Some of the apps didn't have ARM-based image (this was 2019, pre M1 hype era). Didn't want to risk deploying persistent workloads on RPi. A lot of tooling to deploy workloads was missing (storing env variables for eg.). It was so boring to write YAML (that I also did at work). Didn't give me joy. RPi 2x Nodes + K3s + DO Droplet. Tailscale for networking. This was a considerable step up from the previous setup. I deployed a DO node and added Node Labels to deploy persistent workloads on DO Node only.
