You will need kind installed. See https://kind.sigs.k8s.io/docs/user/quick-start/ for details.
You will also need a recent version of kubectl in your PATH
From the main directory, run $ ./start.sh ex1 to start the first exercise. Replace ex1 with any other exercise directory as required.
The Kind cluster will start and be configured for the requested exercise.
Don't forget to export KUBECONFIG for the cluster.
Currently both exercises consist of fixing a deployment that should be accessible via HTTP on http://localhost/ but won't be once the cluster starts.
There are currently no instructions for the exercises. These are still to be written.
