If you are looking for ways to upload your static content in GitLab Pages, you
probably want to read the [user documentation](README.md).
## The GitLab Pages daemon
Starting from GitLab EE 8.5, GitLab Pages make 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. The GitLab
Pages Daemon supports dynamic certificates through SNI and exposes pages using
HTTP2 by default.
Here is a brief list with what it is supported when using the pages daemon:
- Multiple domains per-project
- One TLS certificate per-domain
- Validation of certificate
- Validation of certificate chain
- Validation of private key against certificate
## 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.

### The GitLab Pages daemon and the case of custom domains
---
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, so you basically have three choices:
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

HTTP it's OK to use HTTP or TCP load balancing.
In this document, we will proceed assuming the first option. Let's begin by
installing the pages daemon.
In this document, we will proceed assuming the first option.
### Install the Pages daemon
## Prerequisites
**Source installations**
Before proceeding with the Pages configuration, you will need to:
```
cd /home/git
sudo -u git -H git clone https://gitlab.com/gitlab-org/gitlab-pages.git
cd gitlab-pages
sudo -u git -H git checkout v0.2.1
sudo -u git -H make
```
**Omnibus installations**
The `gitlab-pages` daemon is included in the Omnibus package.
## Configuration
There are multiple ways to set up GitLab Pages according to what URL scheme you
are willing to support.
### Configuration prerequisites
In the next section you will find all possible scenarios to choose from.
In either scenario, you will need:
1. To use the [GitLab Pages daemon](#the-gitlab-pages-daemon)
1. A separate domain
1. A separate Nginx configuration file which needs to be explicitly added in
the server under which GitLab EE runs (Omnibus does that automatically)
1. (Optional) A wildcard certificate for that domain if you decide to serve
pages under HTTPS
1. (Optional but recommended) [Shared runners](../ci/runners/README.md) so that
your users don't have to bring their own
### Configuration scenarios
Before proceeding with setting up GitLab Pages, you have to decide which route
you want to take.
The possible scenarios are depicted in the table below.
| URL scheme | Option | Wildcard certificate | Custom domain with HTTP support | Custom domain with HTTPS support | Secondary IP |
| --- |:---:|:---:|:---:|:---:|:---:|:---:|:---:|
| `http://page.example.io` | 1 | no | no | no | no |
| `https://page.example.io` | 1 | yes | no | no | no |
| `http://page.example.io` and `http://page.com` | 2 | no | yes | no | yes |
| `https://page.example.io` and `https://page.com` | 2 | yes | redirects to HTTPS | yes | yes |
As you see from the table above, each URL scheme comes with an option:
1. Pages enabled, daemon is enabled and NGINX will proxy all requests to the
daemon. Pages daemon doesn't listen to the outside world.
1. 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. Have a separate domain under which the GitLab Pages will be served
1. (Optional) Have a wildcard certificate for that domain if you decide to serve
Pages under HTTPS
1. Configure a wildcard DNS record
1. (Optional but recommended) Enable [Shared runners](../ci/runners/README.md)
so that your users don't have to bring their own

Below are the four scenarios that are described in

Depending on your needs, you can install GitLab Pages in four different ways.
