Clone the latest release, run the installer, and labctl init builds the rest. No Go or Node needed, and no sudo for labctl itself.
kubectl, helm and k3d are installed for you. Before a scenario starts, labctl checks it fits in Docker and tells you what to stop or resize if it doesn’t. Memory per scenario
Apple Silicon or Intel. You don't need Docker Desktop: labctl init installs colima (a small Docker VM) with Homebrew and starts it at 2 CPU / 4 GB. If you already use Docker Desktop, the lab uses that instead. Full macOS guide
Your lab is a clone of the repository: every manifest, values file, scenario and fault is a file you can open and change. install.sh downloads the labctl that matches your clone into ~/.local/bin and checks its checksum. No sudo.
git clone --branch stable https://github.com/sagar2395/snowopslabs.git
cd snowopslabs
./install.shInstalls kubectl, helm, k3d and colima with Homebrew, starts Docker, creates the cluster and installs Traefik, Prometheus and Grafana. If Homebrew is missing it installs that too, which is the one step that asks for your password. The first run downloads a few hundred MB and takes five to ten minutes. If something is wrong, it stops and tells you how to fix it.
