Everything else is simple after that. Use it on a VM as a small, cheap, reliable k8s for CI/CD. I’d recommend microk8s on Ubuntu, it’s been awesome for me. In CI, this often extends to quickly trialing configurations across various Kubernetes clusters, including single-node, high-availability, dual-stack, multi-cluster setups, and more. Is also possible to manage nodes in different cloud with a control plane centrilized, something to provide like a We chose cilium a few years ago because we wanted to run in direct-routing mode to avoid NAT‘ing and the overhead introduced by it. Locking down access prematurely, without knowing what potential use cases could arise, seems to make the least sense to me. Would probably still use minikube for single node work though. I've been using Minikube since a couple of years on my laptop. do you recommend Snap for installing Kubectl, kubelet, and kubeadm? I’m assuming most of the commands will be transferable yea?
