Adding TLS to an ingress

You will now add HTTPS support to your application. To do this, you need a TLS certificate. You will be using the cert-manager Kubernetes add-on to request a certificate from Let's Encrypt.

1. Install cert-manager, which interfaces with the Let's Encrypt API to request a certificate for the domain name you specify.
2. Install the certificate issuer, which will get the certificate from Let's Encrypt.
3. Create an SSL certificate for a given Fully Qualified Domain...
