GitLab Pages custom domains

DETAILS: Tier: Free, Premium, Ultimate Offering: GitLab.com, Self-managed

• Introduced in GitLab 15.4, you can use verified domains to bypass user email confirmation for SAML- or SCIM-provisioned users.

You can use custom domains:

• With GitLab Pages.
• To bypass user email confirmation for SAML- or SCIM-provisioned users. When using custom domains this way, you use the GitLab Pages feature but can skip the prerequisites.

To use one or more custom domain names:

• Add a custom root domain or a subdomain.
• Add SSL/TLS certification.

WARNING: You cannot verify the most popular public email domains.

Set up a custom domain

To set up Pages with a custom domain name, read the requirements and steps below.

Prerequisites

• An administrator has configured the server for GitLab Pages custom domains
• A GitLab Pages website up and running, served under the default Pages domain (*.gitlab.io, for GitLab.com).
• A custom domain name example.com or subdomain subdomain.example.com.
• Access to your domain's server control panel to set up DNS records:
  • A DNS record (A, ALIAS, or CNAME) pointing your domain to the GitLab Pages server. If there are multiple DNS records on that name, you must use an ALIAS record.
  • A DNS TXT record to verify your domain's ownership.

Steps

Follow the steps below to add your custom domain to Pages. See also this document for an overview on DNS records.

1. Add a custom domain

To add your custom domain to GitLab Pages:

1. On the left sidebar, select Search or go to and find your project.
2. Select Deploy > Pages.
3. In the upper-right corner, select New Domain.
4. In Domain, enter the domain name.
5. Optional. In Certificate, turn off the Automatic certificate management using Let's Encrypt toggle to add an SSL/TLS certificate. You can also add the certificate and key later.
6. Select Create New Domain.

2. Get the verification code

After you add a new domain to Pages, the verification code prompts you. Copy the values from GitLab and paste them in your domain's control panel as a TXT record on the next step.

3. Set up DNS records

Read this document for an overview of DNS records for Pages. If you're familiar with the subject, follow the instructions below according to the type of domain you want to use with your Pages site:

• For root domains, example.com.
• For subdomains, subdomain.example.com.
• For both.

You can configure IPv6 on self-managed instances, but IPv6 is not currently configured for Pages on GitLab.com. Follow this issue for details.

For root domains

Root domains (example.com) require:

• A DNS A record pointing your domain to the Pages server.
• A TXT record to verify your domain's ownership.

For projects on GitLab.com, this IP is 35.185.44.232. For projects living in other GitLab instances (CE or EE), contact your sysadmin asking for this information (which IP address is Pages server running on your instance).

WARNING: If you use your root domain for your GitLab Pages website only, and if your domain registrar supports this feature, you can add a DNS apex CNAME record instead of an A record. The main advantage of doing so is that when GitLab Pages IP on GitLab.com changes for whatever reason, you don't need to update your A record. There may be a few exceptions, but this method is not recommended as it most likely doesn't work if you set an MX record for your root domain.

For subdomains

Subdomains (subdomain.example.com) require:

• A DNS ALIAS or CNAME record pointing your subdomain to the Pages server.
• A DNS TXT record to verify your domain's ownership.

Whether it's a user or a project website, the DNS record should point to your Pages domain (namespace.gitlab.io), without any path.

For both root and subdomains

There are a few cases where you need to point both the subdomain and root domain to the same website, for instance, example.com and www.example.com.

They require:

• A DNS A record for the domain.
• A DNS ALIAS/CNAME record for the subdomain.
• A DNS TXT record for each.

If you're using Cloudflare, check Redirecting www.domain.com to domain.com with Cloudflare.

Additionally:

• Do not use a CNAME record if you want to point your domain.com to your GitLab Pages site. Use an A record instead.
• Do not add any special chars after the default Pages domain. For example, don't point subdomain.domain.com to or namespace.gitlab.io/. Some domain hosting providers may request a trailing dot (namespace.gitlab.io.), though.
• GitLab Pages IP on GitLab.com was changed in 2017.
• GitLab Pages IP on GitLab.com has changed from 52.167.214.135 to 35.185.44.232 in 2018.

4. Verify the domain's ownership

After you have added all the DNS records:

1. On the left sidebar, select Search or go to and find your project.
2. Select Deploy > Pages.
3. Next to the domain name, select Edit ({pencil}).
4. In Verification status, select Retry verification ({retry}).

As soon as your domain becomes active, your website is available through your domain name.

WARNING: Considering GitLab instances with domain verification enabled, if the domain can't be verified for 7 days, it's removed from the GitLab project.

Additionally:

• Domain verification is required for GitLab.com users; for GitLab self-managed instances, your GitLab administrator has the option to disabled custom domain verification.
• DNS propagation may take some time (up to 24 hours), although it's usually a matter of minutes to complete. Until it does, verification fails, and attempts to visit your domain result in a 404.
• Once your domain has been verified, leave the verification record in place. Your domain is periodically reverified, and may be disabled if the record is removed.

Add more domain aliases

You can add more than one alias (custom domains and subdomains) to the same project. An alias can be understood as having many doors leading to the same room.

All the aliases you've set to your site are listed on Setting > Pages. From that page, you can view, add, and remove them.

Redirect www.domain.com to domain.com with Cloudflare

If you use Cloudflare, you can redirect www to domain.com without adding both www.domain.com and domain.com to GitLab.

To do so, you can use Cloudflare's page rules associated to a CNAME record to redirect www.domain.com to domain.com. You can use the following setup:

1. In Cloudflare, create a DNS A record pointing domain.com to 35.185.44.232.
2. In GitLab, add the domain to GitLab Pages and get the verification code.
3. In Cloudflare, create a DNS TXT record to verify your domain.
4. In GitLab, verify your domain.
5. In Cloudflare, create a DNS CNAME record pointing www to domain.com.
6. In Cloudflare, add a Page Rule pointing www.domain.com to domain.com:
   • Go to your domain's dashboard and select Page Rules on the top nav.
   • Select Create Page Rule.
   • Enter the domain www.domain.com and select + Add a Setting.
   • From the dropdown list, choose Forwarding URL, then select the status code 301 - Permanent Redirect.
   • Enter the destination URL https://domain.com.

Adding an SSL/TLS certificate to Pages

Read this document for an overview on SSL/TLS certification.

To secure your custom domain with GitLab Pages you can opt by:

• Using the Let's Encrypt integration with GitLab Pages, which automatically obtains and renews SSL certificates for your Pages domains.
• Manually adding SSL/TLS certificates to GitLab Pages websites by following the steps below.

Manual addition of SSL/TLS certificates

You can use any certificate satisfying the following requirements:

• A GitLab Pages website is up and running, accessible on a custom domain.
• A PEM certificate: it is the certificate generated by the CA, which needs to be added to the field Certificate (PEM).
• An intermediate certificate: (aka "root certificate"), it is the part of the encryption keychain that identifies the CA. Usually it's combined with the PEM certificate, but there are some cases in which you need to add them manually. Cloudflare certs are one of these cases.
• A private key, it's an encrypted key which validates your PEM against your domain.

For example, Cloudflare certificates meet these requirements.

Steps

• To add the certificate at the time you add a new domain:

  1. On the left sidebar, select Search or go to and find your project.
  2. On the left sidebar, select Deploy > Pages.
  3. In the upper-right corner, select New Domain.
  4. In Domain, enter the domain name.
  5. In Certificate, turn off the Automatic certificate management using Let's Encrypt toggle to add an SSL/TLS certificate.
  6. Select Create New Domain.

• To add the certificate to a domain previously added:

  1. On the left sidebar, select Search or go to and find your project.
  2. On the left sidebar, select Deploy > Pages.
  3. Next to the domain name, select Edit ({pencil}).
  4. In Certificate, turn off the Automatic certificate management using Let's Encrypt toggle to add an SSL/TLS certificate.
  5. Select Save changes.

1. Add the PEM certificate to its corresponding field.
2. If your certificate is missing its intermediate, copy and paste the root certificate (usually available from your CA website) and paste it in the same field as your PEM certificate, just jumping a line between them.
3. Copy your private key and paste it in the last field.

Do not open certificates or encryption keys in regular text editors. Always use code editors (such as Sublime Text, Dreamweaver, Brackets, etc).

Force HTTPS for GitLab Pages websites

To make your website's visitors even more secure, you can choose to force HTTPS for GitLab Pages. By doing so, all attempts to visit your website through HTTP are automatically redirected to HTTPS through 301.

It works with both the GitLab default domain and with your custom domain (as long as you've set a valid certificate for it).

To enable this setting:

1. On the left sidebar, select Search or go to and find your project.
2. Select Deploy > Pages.
3. Select the Force HTTPS (requires valid certificates) checkbox.
4. Select Save changes.

If you use Cloudflare CDN in front of GitLab Pages, make sure to set the SSL connection setting to full instead of flexible. For more details, see the Cloudflare CDN directions.

Edit a custom domain

You can edit a custom domain to:

• View the custom domain.
• View the DNS record to add.
• View the TXT verification entry.
• Retry verification.
• Edit the certificate settings.

To edit a custom domain:

1. On the left sidebar, select Search or go to and find your project.
2. Select Deploy > Pages.
3. Next to the domain name, select Edit ({pencil}).

Delete a custom domain

After a custom domain is deleted, the domain is no longer verified in GitLab and cannot be used with GitLab Pages.

To delete and remove a custom domain:

1. On the left sidebar, select Search or go to and find your project.
2. Select Deploy > Pages.
3. Next to the domain name, select Remove domain ({remove})
4. When prompted, select Remove domain.

Troubleshooting

Domain verification

To manually verify that you have properly configured the domain verification TXT DNS entry, you can run the following command in your terminal:

dig _gitlab-pages-verification-code.<YOUR-PAGES-DOMAIN> TXT

Expect the output:

;; ANSWER SECTION:
_gitlab-pages-verification-code.<YOUR-PAGES-DOMAIN>. 300 IN TXT "gitlab-pages-verification-code=<YOUR-VERIFICATION-CODE>"

In some cases it can help to add the verification code with the same domain name as you are trying to register.

For a root domain:

For a subdomain:
