Local 2-node practice cluster

The practice tasks assume a real cluster (one control-plane, one worker). This one-command toolkit spins up a kubeadm-based kind cluster on your machine — with Calico (NetworkPolicy), metrics-server, and ingress preinstalled — and resets to a clean state in seconds. Works on Linux, macOS, and Windows. No repo clone needed.

⬇️ Download for Linux / macOS ⬇️ Download for Windows

…or grab it straight from your terminal:

Linux / macOS

curl -fsSL
								https://bartekmp.github.io/cka-learning-tracker/cluster/get.sh |
								bash

Copy

Windows

irm https://bartekmp.github.io/cka-learning-tracker/cluster/get.ps1
								| iex

Copy

Requires Docker running. kind and kubectl are installed automatically if missing. Then run ./setup.sh (or ./setup.ps1) and reset any time with ./reset.sh. Full details in the cluster README ↗.

This is optional. If you can't run a cluster locally (no Docker, low-spec machine, locked-down work laptop), you don't need it — do the tasks in the free, browser-based Killer Coda CKA labs ↗ instead. The two kubeadm tasks (cluster upgrade, bootstrap-from-scratch) are better done there anyway.
