Subdomains are treated like any other domain on BowTie and can be assigned to any environment defined in your project. From your dashboard, visit the More > Domains page and click ‘Add a Domain’. Next, type the subdomain (for a domain you already own or manage) into the field and select the environment you wish to add the domain to. BowTie will automatically configure DNS and SSL for that domain.
