There's a delightfully literal answer to "Kubernetes with Docker": kind — Kubernetes IN Docker. Each node is a Docker container running a full Kubernetes node image. On an Ubuntu workstation it gives you a real, throwaway, multi-node cluster in about 30 seconds. It's my default for local dev and for CI.
Prerequisites on Ubuntu
You need Docker Engine and kubectl. If you don't have Docker yet:
sudo apt-get update && sudo apt-get install -y docker.io
sudo usermod -aG docker $USER && newgrp docker # run docker without sudo
