Creating a Route 53 hosted zone to program DNS entries
The DuploCloud platform needs a unique Route 53 hosted zone to create DNS entries for services that you deploy. The domain must be created out-of-band and set in DuploCloud. The zone is a subdomain such as apps.[MY-COMPANY].com.
Never use this subdomain for anything else, as DuploCloud owns all CNAME entries in this domain and removes all entries it has no record of.
To create the Route53 hosted zone using the AWS Console:
Go to your root Domain Provider's site (for acme.com, for example), and create a NS record that references the domain name of the hosted zone you created (apps.acme.com) and add the zone name to the name servers that you noted above.
Once this is complete, provision the Route53 domain in every DuploCloud Plan, starting with the default plan. Add the Route53 hosted zone ID and domain name, preceded with a dot (.).
Do not forget the dot (.) at the beginning of the DNS suffix, in the form as shown below.
DNS tab for DEFAULT tenant with External/Internal Suffix Values beginning with a dor (.)
Note that this domain must be set in each new Plan you create in your DuploCloud Infrastructure.
