Kubernetes clusters can have hundreds of nodes in production, but you can run a single-node cluster on your laptop and it works in the same way.
We'll also use Git for source control, so you'll need a client on your machine to talk to GitHub.
Git is a free, open source tool for source control:
You'll need your own Azure Subscription, or one which you have Owner permissions for:
The az command is a cross-platform tool for managing Azure resources:
If you're on macOS or Windows 10 Docker Desktop is the easiest way to get Kubernetes:
The download and install takes a few minutes. When it's done, run the Docker app and you'll see the Docker whale logo in your taskbar (Windows) or menu bar (macOS).
On Windows 10 the install may need a restart before you get here.
Right-click that whale and click Settings:
In the settings Windows select Kubernetes from the left menu and click Enable Kubernetes:
Docker downloads all the Kubernetes components and sets them up. That can take a few minutes too. When the Docker logo and the Kubernetes logo in the UI are both green, everything is running.
When you're done you should be able to run these commands and get a response with no errors:
git version
az --version
docker version
kubectl version
Don't worry about the actual version numbers, but if you get errors then we need to look into it.
