Creating a Cluster

This lesson contains instructions regarding creating a Kubernetes cluster.

We'll cover the following...

As always, we will need a cluster. However, this time, it is going to be a bit better defined than before. In the previous section, we gained some insights that should help us create a more robust cluster. It will be regional and scalable. Or, to be more precise, it will be like that if that’s possible.

Note for Minikube and Docker Desktop users
