What is K3s and how does it differ from Kubernetes?

K3s is a lightweight, certified Kubernetes distro—single binary, low-resource, for edges. Drops etcd for SQLite, embeds components; full K8s is heavier for prod clouds.

Can I run K3s on a cheap VPS or phone?

Yes—Android via SSH clients like Termius on a $3 NAT VPS. Use Cloudflared for public access sans IP.

Best ways to optimize K3s on low RAM?

Tiny images, limit ranges, descheduler, single-node with taints. Monitor with lightweight Prometheus.
