Before exposing the Service to the internet, you want to make sure the communication channel is secure. For this, you will need\n\nSelf signed certificates for https (unless you already have an identity certificate) An nginx server configured to use the certificates A secret that makes the certificates accessible to pods\n\nYou can acquire all these from the nginx https example. This requires having go and make tools installed. If you don't want to install those, then follow the manual steps later.
