These instructions will guide you through configuring a GitHub Codespaces environment that you can use to run a basic lab to create containers and one to do a simple deployment in Kubernetes.

These steps must be completed prior to starting the actual labs.

• Ensure that you have created a repository by forking the skillrepos/kint project as a template into your own GitHub area. You do this by clicking the Fork button in the upper right portion of the main project page and following the steps to create a copy in your-github-userid/kint.

1. In your forked repository, start a new codespace.

   • Click the Code button on your repository's landing page.
   • Click the Codespaces tab.
   • Click Create codespaces on main to create the codespace.
   • After the codespace has initialized there will be a terminal present.

2. There is a simple one-node Kubernetes instance called minikube available in your codespace. Start it the following way:

   • Run the following command in the codespace's terminal (This will take several minutes to run...):

     minikube start

   • The output should look similar to the following.

  😄  minikube v1.29.0 on Ubuntu 20.04 (docker/amd64)
  ✨  Automatically selected the docker driver. Other choices: none, ssh
  📌  Using Docker driver with root privileges
  👍  Starting control plane node minikube in cluster minikube
  🚜  Pulling base image ...
  💾  Downloading Kubernetes v1.26.1 preload ...
  ...
  🔎  Verifying Kubernetes components...
  🌟  Enabled addons: storage-provisioner, default-storageclass
  🏄  Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

3. Enable an addon for minikube to provide a local registry to temporarily store images

   • Run the following command in the codespace's terminal:

     minikube addons enable registry

   • The output should look similar to the following:

 💡  registry is an addon maintained by Google. For any concerns contact minikube on GitHub.
 You can view the list of minikube maintainers at: https://github.com/kubernetes/minikube/blob/master/OWNERS
  ▪ Using image gcr.io/google_containers/kube-registry-proxy:0.4
  ▪ Using image docker.io/registry:2.8.1
 🔎  Verifying registry addon...
 🌟  The 'registry' addon is enabled

Open the labs document by clicking on the link below. (Alternatively, you can go to the file tree on the left, find the file named labs.md, right-click on it, and open it with the Preview option.) This will open it up in a tab above your terminal. Then you can follow along with the steps in the labs. Any command in the lab that starts with a $ is intended to be run in the console (without typing the $).
