Customize DNS

Using a free Wildcar DNS (nip.io)

By default, Verrazzano and this module is configured to use nip.io:

configure_dns         = false

By setting the above to false, this ensures nip.io will be used.

Using OCI DNS with API key

This assumes the DNS Zone has already been created and configured in OCI.

  1. Create a file oci.yaml and enter the following:

    auth:
region: us-phoenix-1
tenancy: ocid1.tenancy.oc1.
user: ocid1.user.oc1..
key: |
  -----BEGIN RSA PRIVATE KEY-----
  abcdeefghijklmnopqrstuvwxyz1234567890+/==
  -----END RSA PRIVATE KEY-----
fingerprint: 01:2a:3b:45:6c:78:9d:ee:0f

Warning

The above user should have permission to manage the DNS Zone.

  1. Store the authentication information in an OCI Secret in Vault. Note down the Secret OCID.

  2. Before generating the Verrazzano installation scripts, configure DNS Parameters after the cluster creation:

configure_dns      = true

dns_compartment_id = "ocid1.compartment.oc1.."
dns_secret_id      = "ocid1.vaultsecret.oc1.."
dns_zone_id        = "ocid1.dns-zone.oc1.."
dns_zone_name      = "my.domain"
  1. Run Terraform again to generate the scripts and templates:
terraform apply
