In section 4 of the GKE deployment tutorial there is a note saying that if you cannot buy a domain,
you can continue without it and use IP address instead of domain. Rest of the tutorial uses Let's Encrypt.
However as mentioned in cert-manager/cert-manager#6863 it is not possible to create a certificate for an IP with Let's encrypt. The note should be deleted.
