For this tutorial we are going to use a minikube cluster locally, you do the same steps in any Kubernetes cluster be it managed or self-provisioned.

With the below command, you can easily install minikube on a local Mac and ensure you have Docker pre-installed.

brew install minikube
minikube start

Source: Author’s local mac terminal

Check the status of nodes and pods after minikube has started.

kubectl get nodes
kubectl get pods -A #A means pods from all namespaces

Now, let's helm as we will be using helm to install a HA vault cluster on minikube.

brew install helm
