How to Create a Cloudflare Subdomain (Quick Setup Guide)

In this guide, we will focus on setting up a subdomain in Cloudflare. For more in-depth information about the URL structure, please see our help article on the default URL structure. Please note that we have a guide on changing your site’s domain here.

Requirements for setting up subdomains with Cloudflare:

  • A paid Bolt plan
  • Domain running on Cloudflare
  • Access to the Cloudflare zone

Setting up a Subdomain in Cloudflare

When you are logged in to your Cloudflare account, you’ll first see your Cloudflare zones (if you have access to more than one), and the websites under your control. Navigate to the site to which you’d like to add the subdomain and then to the DNS tab on the left-hand side. 

This is where you’ll find all the site’s DNS records. Add an A record to the DNS to add a subdomain to an existing site. The A-record is to be pointed to your Bolt’s Host IP, which you can find in the “domains” section in the Servebolt Admin Panel.

The actual record pointing to the server will look something like this (keep in mind that the Cloudflare proxy has to be toggled on for the self-signed certificate to work as intended):

You can also look at our Cloudflare and SSL Options FAQ for more information on how to set up your domain’s SSL and TLS settings. Remember that for the Self-signed certificate to serve your site with HTTPS, you must select the “Full” setting in the SSL/TLS overview in Cloudflare to activate a fully secure and encrypted connection.

Once this A-record has been added and the SSL/TLS settings have been set, the subdomain should be up and running and pointing to the Bolt – as long as your site’s setup allows the new subdomain to be reached.

Now all that remains is ensuring everything is working and running as expected by visiting and navigating the site.
