Kubernetes for Developers Deep Dive - lab setup

These instructions will guide you through configuring a GitHub Codespaces environment that you can use to run the course labs.

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

1. Create your own repository for these labs

• Ensure that you have created a repository by forking the skillrepos/k8s-dev-v2 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/k8s-dev-v2 .

2. Configure your codespace

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.

3. Start your single-node Kubernetes cluster

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

- Run the following commands in the codespace's terminal (**This will take several minutes to run...**):

  ```
  minikube start
  ```

- The output should look similar to the following.

😄  minikube v1.30.1 on Ubuntu 20.04 (docker/amd64)
✨  Using the docker driver based on existing profile
👍  Starting control plane node minikube in cluster minikube
🚜  Pulling base image ...
🏃  Updating the running docker "minikube" container ...
🐳  Preparing Kubernetes v1.26.3 on Docker 23.0.2 ...
🔎  Verifying Kubernetes components...
    ▪ Using image gcr.io/k8s-minikube/storage-provisioner:v5
🌟  Enabled addons: storage-provisioner, default-storageclass
🏄  Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default

4. Set aliases

Set up an alias for tooling

alias k=kubectl

5. Open Labs in Preview mode

After the codespace has started, you can close the Welcome doc by clicking on the X in its tab. Then open the labs document by going to the file tree on the left, find the file named codespace-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 gray boxes is either code intended to be run in the console or code to be updated in a file.

6. Set codespace timeout (optional but recommended)

While logged in to GitHub, go to https://github.com/settings/codespaces.

Scroll down and find the section on the page labeled Default idle timeout.

Increase the default timeout value to 90 minutes and then select the Save button.
