Before you can add a custom domain, you'll need to be hosting with Gatsby Cloud. If you haven't already, turn on Gatsby Hosting.
1. Add a Domain
If you just enabled Gatsby Hosting you should already be in the right place. Otherwise, go tot Site Settings > Hosting. Now, click Add Domain above the domain list to start the process
In the Please enter a domain field, add one of the following:
- your apex or root domain (this is your custom domain without the
www.part, e.g. mysite.com)
- your subdomain (e.g., www.mysite.com or store.mysite.com)
Whichever one you choose will become the primary domain for your site.
Redirecting to the Primary Domain
If you add an apex domain, Gatsby Hosting will automatically add a redirect that points the
www. subdomain to the apex domain. Similarly, if you add a
www. subdomain, Gatsby Hosting will automatically add a redirect that points the apex domain to it. Read more about redirected domains in Working with Redirected Domains.
2. Configuring Your Domain Name System (DNS)
Next you'll need to visit your 3rd party DNS registrar (e.g. GoDaddy, NameCheap, etc.) to add some DNS records. A DNS Record is an entry in a DNS with details about how to route a request for a given domain name.
Apex Domain Configuration
If you added an apex domain, you will need to add an Address Mapping Record (A Record).
Copy one of the IP addresses from the value column for the type A records shown next to your custom domain. In your DNS provider's domain settings, create an A Record for the IP address you chose.
The A Record must point to one of the IP addresses shown for your site. It is only necessary to create an A Record for one of the IP addresses listed.
If you added a subdomain, you will need to add a Canonical Name Record (CNAME). The CNAME record must point to the default domain for your site.
How to Add DNS Records for Popular Registrars
Here's documentation on adding DNS records for some popular name registrars:
3. Check DNS Status
Once you've added your DNS record, click Check Status or refresh the page to check that your DNS record has been recognized by Gatsby Hosting.
If your domain fails to validate after 24 hours, try creating an A Record for one of the other IP addresses available instead.
4. Generate SSL Certificate
After the domain is validated, we'll generate a free SSL certificate via Let's Encrypt and automatically configure it. This whole process can take a few minutes to complete.
NOTE: DNS records need to be fully propagated in order to properly verify the certificates. If not, SSL certification generation will fail.
Once your custom domain has the HTTPS On label next to it, you should be able to visit it to see your site live.
If you encounter errors related to the the connection not being secure, please allow a few minutes as it can take time for DNS changes to take effect and be detected by all browsers. Use this time to verify that you followed the above steps completely.
If you see the following when you visit your custom domain, the site may still be building.
Check the Deploys tab for your site to see the current status of your builds.
