Custom domain & DNS

You can expose your application on your own domain (e.g. app.mycompany.com) on top of the automatic subdomain.

1. Declare the domain in Nubiecloud

At deployment time (or through the deployment update), fill in the Custom domain field.

• One or several domains, comma-separated: app.mycompany.com, www.mycompany.com.
• Allowed characters: letters, digits, dashes and dots. No wildcard (*.mycompany.com is not accepted).

2. Configure the DNS

At your domain provider, create a CNAME record pointing your domain at your application's Nubiecloud subdomain (the exact instruction is recalled in the console).

app.mycompany.com.  CNAME  app-name-xxxx.<nubiecloud-apps-domain>.

⚠️ The TLS certificate can only be issued once DNS resolution is live. Allow for DNS propagation time (from a few minutes to a few hours depending on your provider).

3. Automatic TLS

As soon as the domain points correctly, Nubiecloud automatically issues the TLS certificate (Let's Encrypt) and renews it with no intervention. Your custom domain then answers over HTTPS.

Verify

Open your domain in a browser: it should show your application over HTTPS with a valid certificate.

ℹ️ The console does not (yet) show a detailed indicator of the certificate's or the DNS resolution's status. If the domain does not answer after propagation, check your CNAME record, then see the "Domain that does not resolve" troubleshooting.
