> "Where kubeadm created a headache for Raspberry Pi, K3s made things simple with an easy boostrap, low resource requirements and a single binary for distribution and updates."<p>I'm curious what the headache was. K8S has shipped arm kubeadm and kubelet bins for quite a while.<p>I also don't understand how k3s, microkube and others claim to be "lightweight". Lightweight compared to what? Certainly not upstream kubeadm which is as lightweight a bootstrap as you can get.<p>> "Given how much I'd liked the Docker experience of "docker swarm init" and "docker swarm join", I decided to re-create a similar experience for K3s in the k3sup tool"<p>"kubeadm init" and "kubeadm join"
