In case you want to use -GitLab Pages with your own (sub)domain, you need to access your domain's -registrar control panel to add a DNS record pointing it back to your -GitLab Pages site. - -Note that **how to** add DNS records depends on which server your domain -is hosted on. Every control panel has its own place to do it. If you are -not an admin of your domain, and don't have access to your registrar, -you'll need to ask for the technical support of your hosting service -to do it for you. - -To help you out, we've gathered some instructions on how to do that -for the most popular hosting services: - -- [Amazon](http://docs.aws.amazon.com/gettingstarted/latest/swh/getting-started-configure-route53.html) -- [Bluehost](https://my.bluehost.com/cgi/help/559) -- [CloudFlare](https://support.cloudflare.com/hc/en-us/articles/200169096-How-do-I-add-A-records-) -- [cPanel](https://documentation.cpanel.net/display/ALD/Edit+DNS+Zone) -- [DreamHost](https://help.dreamhost.com/hc/en-us/articles/215414867-How-do-I-add-custom-DNS-records-) -- [Go Daddy](https://www.godaddy.com/help/add-an-a-record-19238) -- [Hostgator](http://support.hostgator.com/articles/changing-dns-records) -- [Inmotion hosting](https://my.bluehost.com/cgi/help/559) -- [Media Temple](https://mediatemple.net/community/products/dv/204403794/how-can-i-change-the-dns-records-for-my-domain) -- [Microsoft](https://msdn.microsoft.com/en-us/library/bb727018.aspx) - -If your hosting service is not listed above, you can just try to -search the web for `how to add dns record on <my hosting service>`. - -#### DNS A record - -In case you want to point a root domain (`example.com`) to your -GitLab Pages site, deployed to `namespace.gitlab.io`, you need to -log into your domain's admin control panel and add a DNS `A` record -pointing your domain to Pages' server IP address. For projects on -GitLab.com, this IP is `35.185.44.232`. For projects living in -other GitLab instances (CE or EE), please contact your sysadmin -asking for this information (which IP address is Pages server -running on your instance). - -**Practical Example:** - - - -CAUTION: **Caution:** -Note that 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 won't work if you set an `MX` record for your root domain. - -#### DNS CNAME record - -In case you want to point a subdomain (`hello-world.example.com`) -to your GitLab Pages site initially deployed to `namespace.gitlab.io`, -you need to log into your domain's admin control panel and add a DNS -`CNAME` record pointing your subdomain to your website URL -(`namespace.gitlab.io`) address. - -Note that, whether it's a user or a project website, the `CNAME` -should point to your Pages domain (`namespace.gitlab.io`), -without any `/project-name`. - -**Practical Example:** - - - -#### DNS TXT record - -Unless your GitLab administrator has [disabled custom domain verification](../../../administration/pages/index.md#custom-domain-verification), -you'll have to prove that you own the domain by creating a `TXT` record -containing a verification code. The code will be displayed after you -[add your custom domain to GitLab Pages settings](#add-your-custom-domain-to-gitlab-pages-settings). - -If using a [DNS A record](#dns-a-record), you can place the TXT record directly -under the domain. If using a [DNS CNAME record](#dns-cname-record), the two record types won't -co-exist, so you need to place the TXT record in a special subdomain of its own. - -If the domain cannot be verified for 7 days, it will be removed from the GitLab project. - -#### TL;DR - -For root domains (`domain.com`), set a DNS `A` record and verify your -domain's ownership with a TXT record: - -| From | DNS Record | To | -| ---- | ---------- | -- | -| domain.com | A | 35.185.44.232 | -| domain.com | TXT | gitlab-pages-verification-code=00112233445566778899aabbccddeeff | - -For subdomains (`subdomain.domain.com`), set a DNS `CNAME` record and -verify your domain's ownership with a TXT record: - -| From | DNS Record | To | -| ---- | ---------- | -- | -| subdomain.domain.com | CNAME | namespace.gitlab.io | -| _gitlab-pages-verification-code.subdomain.domain.com | TXT | gitlab-pages-verification-code=00112233445566778899aabbccddeeff | - -> **Notes**: -> -> - **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. E.g., **do not** point your `subdomain.domain.com` to - `namespace.gitlab.io.` or `namespace.gitlab.io/`. -> - GitLab Pages IP on GitLab.com [was changed](https://about.gitlab.com/2017/03/06/we-are-changing-the-ip-of-gitlab-pages-on-gitlab-com/) in 2017. -> - GitLab Pages IP on GitLab.com [has been changed](https://about.gitlab.com/2018/07/19/gcp-move-update/#gitlab-pages-and-custom-domains) - from `52.167.214.135` to `35.185.44.232` in 2018. - -### Add your custom domain to GitLab Pages settings - -Once you've set the DNS record, you'll need navigate to your project's -**Setting > Pages** and click **+ New domain** to add your custom domain to -GitLab Pages. You can choose whether to add an [SSL/TLS certificate](#ssltls-certificates) -to make your website accessible under HTTPS or leave it blank. If you don't add a certificate, -your site will be accessible only via HTTP: - - - -Once you have added a new domain, you will need to **verify your ownership** -(unless the GitLab administrator has disabled this feature). A verification code -will be shown to you; add it as a [DNS TXT record](#dns-txt-record), then press -the "Verify ownership" button to activate your new domain: - - - -Once your domain has been verified, leave the verification record in place - -your domain will be periodically reverified, and may be disabled if the record -is removed. - -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 will be listed on **Setting > Pages**. -From that page, you can view, add, and remove them. - -Note that [DNS propagation may take some time (up to 24h)](http://www.inmotionhosting.com/support/domain-names/dns-nameserver-changes/domain-names-dns-changes), -although it's usually a matter of minutes to complete. Until it does, verification -will fail and attempts to visit your domain will respond with a 404. - -### Redirecting `www.domain.com` to `domain.com` with Cloudflare - -If you use Cloudflare, you can redirect `www` to `domain.com` without the need of adding both -`www.domain.com` and `domain.com` to GitLab. This happens due to a [Cloudflare feature that creates -a 301 redirect as a "page rule"](https://gitlab.com/gitlab-org/gitlab-ce/issues/48848#note_87314849) for redirecting `www.domain.com` to `domain.com`. In this case, -you can use the following setup: - -- In Cloudflare, create a DNS `A` record pointing `domain.com` to `35.185.44.232` -- In GitLab, add the domain to GitLab Pages -- In Cloudflare, create a DNS `TXT` record to verify your domain -- In Cloudflare, create a DNS `CNAME` record pointing `www` to `domain.com` - -## SSL/TLS Certificates - -Every GitLab Pages project on GitLab.com will be available under -HTTPS for the default Pages domain (`*.gitlab.io`). Once you set -up your Pages project with your custom (sub)domain, if you want -it secured by HTTPS, you will have to issue a certificate for that -(sub)domain and install it on your project. - ->**Note:** -Certificates are NOT required to add to your custom -(sub)domain on your GitLab Pages project, though they are -highly recommendable. - -Let's start with an introduction to the importance of HTTPS. -Alternatively, jump ahead to [adding certificates to your project](#adding-certificates-to-pages). - -### Why should I care about HTTPS? - -This might be your first question. If our sites are hosted by GitLab Pages, -they are static, hence we are not dealing with server-side scripts -nor credit card transactions, then why do we need secure connections? - -Back in the 1990s, where HTTPS came out, [SSL](https://en.wikipedia.org/wiki/Transport_Layer_Security#SSL_1.0.2C_2.0_and_3.0) was considered a "special" -security measure, necessary just for big companies, like banks and shoppings sites -with financial transactions. -Now we have a different picture. [According to Josh Aas](https://letsencrypt.org/2015/10/29/phishing-and-malware.html), Executive Director at [ISRG](https://en.wikipedia.org/wiki/Internet_Security_Research_Group): - -> _We’ve since come to realize that HTTPS is important for almost all websites. It’s important for any website that allows people to log in with a password, any website that [tracks its users](https://www.washingtonpost.com/news/the-switch/wp/2013/12/10/nsa-uses-google-cookies-to-pinpoint-targets-for-hacking/) in any way, any website that [doesn’t want its content altered](http://arstechnica.com/tech-policy/2014/09/why-comcasts-javascript-ad-injections-threaten-security-net-neutrality/), and for any site that offers content people might not want others to know they are consuming. We’ve also learned that any site not secured by HTTPS [can be used to attack other sites](https://krebsonsecurity.com/2015/04/dont-be-fodder-for-chinas-great-cannon/)._ - -Therefore, the reason why certificates are so important is that they encrypt -the connection between the **client** (you, me, your visitors) -and the **server** (where you site lives), through a keychain of -authentications and validations. - -How about taking Josh's advice and protecting our sites too? We will be -well supported, and we'll contribute to a safer internet. - -### Organizations supporting HTTPS - -There is a huge movement in favor of securing all the web. W3C fully -[supports the cause](https://w3ctag.github.io/web-https/) and explains very well -the reasons for that. Richard Barnes, a writer for Mozilla Security Blog, -suggested that [Firefox would deprecate HTTP](https://blog.mozilla.org/security/2015/04/30/deprecating-non-secure-http/), -and would no longer accept unsecured connections. Recently, Mozilla published a -[communication](https://blog.mozilla.org/security/2016/03/29/march-2016-ca-communication/) -reiterating the importance of HTTPS. - -## Issuing Certificates - -GitLab Pages accepts certificates provided in the [PEM](https://support.quovadisglobal.com/kb/a37/what-is-pem-format.aspx) format, issued by -[Certificate Authorities (CAs)](https://en.wikipedia.org/wiki/Certificate_authority) or as -[self-signed certificates](https://en.wikipedia.org/wiki/Self-signed_certificate). Note that [self-signed certificates are typically not used](https://securingtomorrow.mcafee.com/other-blogs/mcafee-labs/self-signed-certificates-secure-so-why-ban/) -for public websites for security reasons and to ensure that browsers trust your site's certificate. - -There are various kinds of certificates, each one -with a certain security level. A static personal website will -not require the same security level as an online banking web app, -for instance. - -There are some certificate authorities that -offer free certificates, aiming to make the internet more secure -to everyone. The most popular is [Let's Encrypt](https://letsencrypt.org/), -which issues certificates trusted by most of browsers, it's open -source, and free to use. See our tutorial on [how to secure your GitLab Pages website with Let's Encrypt](lets_encrypt_for_gitlab_pages.md). - -Similarly popular are [certificates issued by CloudFlare](https://www.cloudflare.com/ssl/), -which also offers a [free CDN service](https://blog.cloudflare.com/cloudflares-free-cdn-and-you/). -Their certs are valid up to 15 years. See the tutorial on -[how to add a CloudFlare Certificate to your GitLab Pages website](https://about.gitlab.com/2017/02/07/setting-up-gitlab-pages-with-cloudflare-certificates/). - -### Adding certificates to Pages - -Regardless the CA you choose, the steps to add your certificate to -your Pages project are the same. - -#### Requirements - -1. A PEM certificate -1. An intermediate certificate -1. A private key - - - -These fields are found under your **Project**'s **Settings** > **Pages** > **New Domain**. - -#### Certificate types - -- A PEM certificate is the certificate generated by the CA, - which needs to be added to the field **Certificate (PEM)**. -- An [intermediate certificate](https://en.wikipedia.org/wiki/Intermediate_certificate_authority) (aka "root certificate") 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](https://about.gitlab.com/2017/02/07/setting-up-gitlab-pages-with-cloudflare-certificates/) - are one of these cases. -- A private key is an encrypted key which validates - your PEM against your domain. - -#### Add the certificate to your project - -Once you've met the requirements: - -- Your PEM certificate needs to be added to the first field. -- 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](https://about.gitlab.com/2017/02/07/setting-up-gitlab-pages-with-cloudflare-certificates/), - just jumping a line between them. -- Copy your private key and paste it in the last field. - -NOTE: **Note:** -**Do not** open certificates or encryption keys in -regular text editors. Always use code editors (such as -Sublime Text, Atom, Dreamweaver, Brackets, etc). - -## Force HTTPS for GitLab Pages websites - -> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/issues/28857) in GitLab 10.7. - -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 via HTTP will be automatically redirected to HTTPS via 301. - -It works with both GitLab's default domain and with your custom -domain (as long as you've set a valid certificate for it). - -To enable this setting, navigate to your project's **Settings > Pages** -and tick the checkbox **Force HTTPS (requires valid certificates)**. +This document was moved to [another location](custom_domains_ssl_tls_certification/index.md). |
