# Online Talk part 1: User creation

# At the end of this script, you will have a new user in your 
# minikube cluster

# We will use jsalmeron as the example user

## Create cert dirs
mkdir -p ~/.certs/kubernetes/minikube/

## Private key
openssl genrsa -out ~/.certs/kubernetes/minikube/jsalmeron.key 2048

## Certificate sign request
openssl req -new -key ~/.certs/kubernetes/minikube/jsalmeron.key -out /tmp/jsalmeron.csr -subj "/CN=jsalmeron/O=devs/O=tech-lead"

## Certificate
