#setup

Install Docker Engine and the Compose plugin on Ubuntu from Docker's official apt repository, then run docker without sudo.

Install the kubectl CLI on Linux or macOS, enable shell completion and a k alias, and verify the client version.

Spin up a disposable Kubernetes cluster on your laptop inside Docker with kind (fast, multi-node) or minikube (dashboard and addons).

Bootstrap a real multi-node cluster on Ubuntu VMs with kubeadm and containerd: prepare nodes, init the control plane, install a CNI, join workers.

Copies a remote repository — full history included — into a new local directory and wires up 'origin' automatically.

Creates a new, empty Git repository — a .git directory holding all history — in the current folder.
