# GitLab Pages Administration
> **Notes:**
- [Introduced][ee-80] in GitLab EE 8.3.
- Custom CNAMEs with TLS support were [introduced][ee-173] in GitLab EE 8.5.
- GitLab Pages [were ported][ce-14605] to Community Edition in GitLab 8.17.
- This guide is for Omnibus GitLab installations. If you have installed
GitLab from source, follow the [Pages source installation document](source.md).
---
This document describes how to set up the _latest_ GitLab Pages feature. Make
sure to read the [changelog](#changelog) if you are upgrading to a new GitLab
version as it may include new features and changes needed to be made in your
configuration.
If you are looking for ways to upload your static content in GitLab Pages, you
probably want to read the [user documentation][pages-userguide].
## Overview
GitLab Pages makes use of the [GitLab Pages daemon], a simple HTTP server
written in Go that can listen on an external IP address and provide support for
custom domains and custom certificates. It supports dynamic certificates through
SNI and exposes pages using HTTP2 by default.
You are encouraged to read its [README][pages-readme] to fully understand how
it works.
---
In the case of custom domains, the Pages daemon needs to listen on ports `80`
and/or `443`. For that reason, there is some flexibility in the way which you
can set it up:
1. Run the pages daemon in the same server as GitLab, listening on a secondary IP
1. Run the pages daemon in a separate server. In that case, the
[Pages path](#change-storage-path) must also be present in the server that
the pages daemon is installed, so you will have to share it via network.
1. Run the pages daemon in the same server as GitLab, listening on the same IP
but on different ports. In that case, you will have to proxy the traffic with
a loadbalancer. If you choose that route note that you should use TCP load
balancing for HTTPS. If you use TLS-termination (HTTPS-load balancing) the
pages will not be able to be served with user provided certificates. For
HTTP it's OK to use HTTP or TCP load balancing.
In this document, we will proceed assuming the first option.
## Prerequisites
Before proceeding with the Pages configuration, you will need to:
1. Have a separate domain under which the GitLab Pages will be served. In this
document we assume that to be `example.io`.
1. Configure a **wildcard DNS record**.
1. (Optional) Have a **wildcard certificate** for that domain if you decide to
serve Pages under HTTPS.
1. (Optional but recommended) Enable [Shared runners](../../ci/runners/README.md)
so that your users don't have to bring their own.
### DNS configuration
GitLab Pages expect to run on their own virtual host. In your DNS server/provider
you need to add a [wildcard DNS A record][wiki-wildcard-dns] pointing to the
host that GitLab runs. For example, an entry would look like this:
```
*.example.io. 1800 IN A 1.2.3.4
```
where `example.io` is the domain under which GitLab Pages will be served
and `1.2.3.4` is the IP address of your GitLab instance.
> **Note:**
You should not use the GitLab domain to serve user pages. For more information
see the [security section](#security).
[wiki-wildcard-dns]: https://en.wikipedia.org/wiki/Wildcard_DNS_record
## Configuration
Depending on your needs, you can install GitLab Pages in four different ways.
### Option 1. Custom domains with HTTPS support
| URL scheme | Wildcard certificate | Custom domain with HTTP support | Custom domain with HTTPS support | Secondary IP |
| --- |:---:|:---:|:---:|:---:|:---:|:---:|:---:|
| `https://page.example.io` and `https://page.com` | yes | redirects to HTTPS | yes | yes |
Pages enabled, daemon is enabled AND pages has external IP support enabled.
In that case, the pages daemon is running, NGINX still proxies requests to
the daemon but the daemon is also able to receive requests from the outside
world. Custom domains and TLS are supported.
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
pages_external_url "https://example.io"
nginx['listen_addresses'] = ['1.1.1.1']
pages_nginx['enable'] = false
gitlab_pages['cert'] = "/etc/gitlab/ssl/example.io.crt"
gitlab_pages['cert_key'] = "/etc/gitlab/ssl/example.io.key"
gitlab_pages['external_http'] = '1.1.1.2:80'
gitlab_pages['external_https'] = '1.1.1.2:443'
```
where `1.1.1.1` is the primary IP address that GitLab is listening to and
`1.1.1.2` the secondary IP where the GitLab Pages daemon listens to.
1. [Reconfigure GitLab][reconfigure]
### Option 2. Custom domains without HTTPS support
| URL scheme | Wildcard certificate | Custom domain with HTTP support | Custom domain with HTTPS support | Secondary IP |
| --- |:---:|:---:|:---:|:---:|:---:|:---:|:---:|
| `http://page.example.io` and `http://page.com` | no | yes | no | yes |
Pages enabled, daemon is enabled AND pages has external IP support enabled.
In that case, the pages daemon is running, NGINX still proxies requests to
the daemon but the daemon is also able to receive requests from the outside
world. Custom domains and TLS are supported.
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
pages_external_url "http://example.io"
nginx['listen_addresses'] = ['1.1.1.1']
pages_nginx['enable'] = false
gitlab_pages['external_http'] = '1.1.1.2:80'
```
where `1.1.1.1` is the primary IP address that GitLab is listening to and
`1.1.1.2` the secondary IP where the GitLab Pages daemon listens to.
1. [Reconfigure GitLab][reconfigure]
### Option 3. Wildcard HTTPS domain without custom domains
| URL scheme | Wildcard certificate | Custom domain with HTTP support | Custom domain with HTTPS support | Secondary IP |
| --- |:---:|:---:|:---:|:---:|:---:|:---:|:---:|
| `https://page.example.io` | yes | no | no | no |
Pages enabled, daemon is enabled and NGINX will proxy all requests to the
daemon. Pages daemon doesn't listen to the outside world.
1. Place the certificate and key inside `/etc/gitlab/ssl`
1. In `/etc/gitlab/gitlab.rb` specify the following configuration:
```ruby
pages_external_url 'https://example.io'
pages_nginx['redirect_http_to_https'] = true
pages_nginx['ssl_certificate'] = "/etc/gitlab/ssl/pages-nginx.crt"
pages_nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/pages-nginx.key"
```
where `pages-nginx.crt` and `pages-nginx.key` are the SSL cert and key,
respectively.
1. [Reconfigure GitLab][reconfigure]
### Option 4. Wildcard HTTP domain without custom domains
| URL scheme | Wildcard certificate | Custom domain with HTTP support | Custom domain with HTTPS support | Secondary IP |
| --- |:---:|:---:|:---:|:---:|:---:|:---:|:---:|
| `http://page.example.io` | no | no | no | no |
Pages enabled, daemon is enabled and NGINX will proxy all requests to the
daemon. Pages daemon doesn't listen to the outside world.
1. Set the external URL for GitLab Pages in `/etc/gitlab/gitlab.rb`:
```ruby
pages_external_url 'http://example.io'
```
1. [Reconfigure GitLab][reconfigure]
## Change storage path
Follow the steps below to change the default path where GitLab Pages' contents
are stored.
1. Pages are stored by default in `/var/opt/gitlab/gitlab-rails/shared/pages`.
If you wish to store them in another location you must set it up in
`/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['pages_path'] = "/mnt/storage/pages"
```
1. [Reconfigure GitLab][reconfigure]
## Set maximum pages size
The maximum size of the unpacked archive per project can be configured in the
Admin area under the Application settings in the **Maximum size of pages (MB)**.
The default is 100MB.
## Backup
Pages are part of the [regular backup][backup] so there is nothing to configure.
## Security
You should strongly consider running GitLab pages under a different hostname
than GitLab to prevent XSS attacks.
## Changelog
GitLab Pages were first introduced in GitLab EE 8.3. Since then, many features
where added, like custom CNAME and TLS support, and many more are likely to
come. Below is a brief changelog. If no changes were introduced or a version is
missing from the changelog, assume that the documentation is the same as the
latest previous version.
