Generate TSL

https://kubernetes.github.io/ingress-nginx/examples/PREREQUISITES/#test-http-service

openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=nginxsvc/O=nginxsvc"

kubectl create secret tls tls-secret --key tls.key --cert tls.crt

Check version

# Run /nginx-ingress-controller --version within the pod, for instance with kubectl exec:

POD_NAMESPACE=ingress-nginx
POD_NAME=$(kubectl get pods -n $POD_NAMESPACE -l app.kubernetes.io/name=ingress-nginx --field-selector=status.phase=Running -o name)
kubectl exec $POD_NAME -n $POD_NAMESPACE -- /nginx-ingress-controller --version
