To create a CNAME in your DigitalOcean managed domain, first visit the Networking Tab within the DigitalOcean Cloud Control Panel, then select your zone from the list. Just below “Create New Record” on your zone-management page, click “CNAME”. In the hostname, put the subdomain you’re looking to create. For example, if you are trying to configure www.example.com, the hostname box should say “www”. In the next box (titled “IS AN ALIAS OF”) put your app’s full ondigitalocean.app URL. This should be something like “example-app-123456.ondigitalocean.app”. Then click “Create Record”.

Once this is complete, return to your apps control panel, select the app, and click “Settings”. Click “edit” network to the Domains line and then if the domain you’re adding isn’t already listed click “+ Add Domain”. Enter the full domain (www.example.com in the example above) and click “Add Domain”. Once this process is complete, the domain should be active in approximately 60 minutes.

If you’re seeing CloudFlare Error 1001 it’s possible you missed adding the domain to your app–the second set of steps above. DigitalOcean App Platform uses the CloudFlare network to provide CDN functionality and to protect your website from some threats.
