Environment Setup

We need a running Kubernetes cluster and some tools for our experiments. If you have a cluster already preconfigured, you can skip this section. Otherwise, let’s install minikube locally (e.g. for MacOS):

• Python >= 3.8 (running in a venv is recommended, though is not necessary).

• Install kubectl

• Install minikube (a local Kubernetes cluster)

• Install Kopf

Warning

Unfortunately, Minikube cannot handle the PVC/PV resizing, as it uses the HostPath provider internally. You can either skip the Updating the objects step of this tutorial (where the sizes of the volumes are changed), or you can use an external Kubernetes cluster with real dynamically sized volumes.
