minikube is the other "Kubernetes in Docker" option on Ubuntu, and with --driver=docker it runs the cluster inside a Docker container just like kind — but ships with addons (ingress, metrics-server, dashboard, a built-in registry) that make it feel more like a real cluster. Here's a practical setup and how it differs from kind.
Install on Ubuntu
You need Docker first (sudo apt-get install -y docker.io, then add yourself to the docker group). Then:
curl -fsSLo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube /usr/local/bin/minikube
