k3d cuts Kubernetes cluster startup from 3 minutes to under 10 seconds

Short summary

A team replaced minikube and Docker Desktop Kubernetes with k3d, cutting cluster startup from 3 minutes to under 10 seconds. k3d runs k3s (Rancher's lightweight Kubernetes) as Docker containers with SQLite instead of etcd, making cluster recreation trivial. The article includes a single-command cluster setup with multi-node scheduling, a built-in registry, and ingress port forwarding, plus honest comparisons with kind and minikube.

• •k3d runs k3s-in-Docker, cutting local cluster startup from 3 min to <10 seconds
• •Single command creates 3-node cluster with built-in registry and ingress forwarding
• •Honest comparison: k3d for speed, kind for prod parity, minikube for learning
