This is the courseware for Tim Solley's Docker and Kubernetes courses. It includes exercise files for lectures as well as a Hackthon application for students to practice the concepts they learn in class.

You'll need to install a container runtime for this course. You have a couple of good options:

With Docker Desktop, you'll get a managed Kubernetes cluster after some initial setup. IMPORTANT: This has a potential license issue, as Docker charges larger companies a per-seat license fee. It is free for your personal/educational use. It is free for use during class, but a license requirement applies once the class is over. If you're unsure, check with your company management or choose the Rancher Desktop option below. For more details on Docker's license and whether it applies to you at work, visit their FAQ.

1. Visit docker.com
2. Click the install link in the center of the page. Be careful if you're on a Mac to choose the correct chip. It defaults to Intel Macs. If you're unsure, look at the Apple menu on your computer, then About This Mac.
3. Once installed, open the Docker application.
4. You'll have Docker menu on your computer (whale logo). Click it and choose the Signup/Signin to Docker Hub option. This will open a browser to Docker Hub where you can login or sign up for a free account.
5. (For Kubernetes courses) Install Kubernetes
   1. Once you're signed in, open the Docker menu again and choose Preferences. Then go to the Kubernetes section. Check the box for Enable Kubernetes then click the Apply and Restart button. This will begin the Kubernetes setup process which usually takes 10-15 minutes.
   2. Once finished, you'll be able to open a terminal and run kubectl get all and get some output that is clearly not a connection error.

A great open-source option with no license issues. Rancher Desktop comes with automatic Kubernetes support.

1. Visit rancherdesktop.io
2. Scroll down to the installer section and pick the correct installer. Be careful if you're on a Mac to choose the correct chip. It defaults to Intel Macs. If you're unsure, look at the Apple menu on your computer, then About This Mac.
3. Follow the installation instructions. When prompted for for container engine, choose dockerd (moby). When prompted for a Kubernetes version, choose the latest stable release.

k3d offers a great way to start up a multi-node cluster on your local workstation using Docker containers as Kubernetes nodes. This allows you to work in a simulated large cluster environment to practice cluster management. I've tested this using Rancher Desktop, but it should work fine for Docker Desktop.

1. Visit k3d.io for more detailed instructions.
2. In a terminal, run wget -q -O - https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | bash. Alternatively, you can use Homebrew with brew install k3d
3. Set up your cluster. In this repository, navigate to the k3d directory. Run make create-cluster or open the Makefile and grab the command and run it.
4. To switch your Kubernetes context to the k3d cluster, run kubectl config use-context k3d-k3d
