GitLab Pages administration

GitLab Pages allows for hosting of static sites. It must be configured by an administrator. Separate user documentation is available.

The GitLab Pages daemon

GitLab Pages makes use of the GitLab Pages daemon, a basic 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 Server Name Indication (SNI) and exposes pages using HTTP2 by default. You are encouraged to read its README to fully understand how it works.

In the case of custom domains (but not wildcard 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:

• Run the Pages daemon in the same server as GitLab, listening on a secondary IP.
• Run the Pages daemon in a separate server. In that case, the Pages path must also be present in the server that the Pages daemon is installed, so you must share it through the network.
• Run the Pages daemon in the same server as GitLab, listening on the same IP but on different ports. In that case, you must proxy the traffic with a load balancer. If you choose that route, you should use TCP load balancing for HTTPS. If you use TLS-termination (HTTPS-load balancing), the pages can’t be served with user-provided certificates. For HTTP it’s OK to use HTTP or TCP load balancing.

In this document, we proceed assuming the first option. If you are not supporting custom domains a secondary IP is not needed.

Prerequisites

Before proceeding with the Pages configuration, you must:

1. Have a domain for Pages that is not a subdomain of your GitLab instance domain.

   GitLab domain	Pages domain	Does it work?
   example.com	example.io	Yes
   example.com	pages.example.com	No
   gitlab.example.com	pages.example.com	Yes

2. Configure a wildcard DNS record.
3. Optional. Have a wildcard certificate for that domain if you decide to serve Pages under HTTPS.
4. Optional but recommended. Enable Shared runners so that your users don’t have to bring their own.
5. For custom domains, have a secondary IP.

Add the domain to the Public Suffix List

The Public Suffix List is used by browsers to decide how to treat subdomains. If your GitLab instance allows members of the public to create GitLab Pages sites, it also allows those users to create subdomains on the pages domain (example.io). Adding the domain to the Public Suffix List prevents browsers from accepting supercookies, among other things.

Follow these instructions to submit your GitLab Pages subdomain. For instance, if your domain is example.io, you should request that example.io is added to the Public Suffix List. GitLab.com added gitlab.io in 2016.

DNS configuration

GitLab Pages expect to run on their own virtual host. In your DNS server/provider add a wildcard DNS A record pointing to the host that GitLab runs. For example, an entry would look like this:

*.example.io. 1800 IN A    192.0.2.1
*.example.io. 1800 IN AAAA 2001:db8::1

Where example.io is the domain GitLab Pages is served from, 192.0.2.1 is the IPv4 address of your GitLab instance, and 2001:db8::1 is the IPv6 address. If you don’t have IPv6, you can omit the AAAA record.

DNS configuration for custom domains

If support for custom domains is needed, all subdomains of the Pages root domain should point to the secondary IP (which is dedicated for the Pages daemon). Without this configuration, users can’t use CNAME records to point their custom domains to their GitLab Pages.

For example, an entry could look like this:

example.com   1800 IN A    192.0.2.1
*.example.io. 1800 IN A    192.0.2.2

This example contains the following:

• example.com: The GitLab domain.
• example.io: The domain GitLab Pages is served from.
• 192.0.2.1: The primary IP of your GitLab instance.
• 192.0.2.2: The secondary IP, which is dedicated to GitLab Pages. It must be different than the primary IP.

Configuration

Depending on your needs, you can set up GitLab Pages in 4 different ways.

The following examples are listed from the easiest setup to the most advanced one. The absolute minimum requirement is to set up the wildcard DNS because that is needed in all configurations.

Wildcard domains

Requirements:

• Wildcard DNS setup

URL scheme: http://<namespace>.example.io/<project_slug>

The following is the minimum setup that you can use Pages with. It is the base for all other setups as described below. NGINX proxies all requests to the daemon. The Pages daemon doesn’t listen to the outside world.

1. Set the external URL for GitLab Pages in /etc/gitlab/gitlab.rb:

   external_url "http://example.com" # external_url here is only for reference
   pages_external_url 'http://example.io' # Important: not a subdomain of external_url, so cannot be http://pages.example.com
   

2. Reconfigure GitLab.

Watch the video tutorial for this configuration.

Wildcard domains with TLS support

Requirements:

• Wildcard DNS setup
• TLS certificate. Can be either Wildcard, or any other type meeting the requirements.

URL scheme: https://<namespace>.example.io/<project_slug>

NGINX proxies all requests to the daemon. Pages daemon doesn’t listen to the outside world.

1. Place the wildcard LTS certificate for *.example.io and the key inside /etc/gitlab/ssl.

2. In /etc/gitlab/gitlab.rb specify the following configuration:

   external_url "https://example.com" # external_url here is only for reference
   pages_external_url 'https://example.io' # Important: not a subdomain of external_url, so cannot be https://pages.example.com
   
   pages_nginx['redirect_http_to_https'] = true
   

3. If you haven’t named your certificate and key example.io.crt and example.io.key, you must also add the full paths as shown below:

   pages_nginx['ssl_certificate'] = "/etc/gitlab/ssl/pages-nginx.crt"
   pages_nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/pages-nginx.key"
   

4. Reconfigure GitLab.
5. If you’re using Pages Access Control, update the redirect URI in the GitLab Pages System OAuth application to use the HTTPS protocol.

Wildcard domains with TLS-terminating Load Balancer

Requirements:

• Wildcard DNS setup
• TLS-terminating load balancer

URL scheme: https://<namespace>.example.io/<project_slug>

This setup is primarily intended to be used when installing a GitLab POC on Amazon Web Services. This includes a TLS-terminating classic load balancer that listens for HTTPS connections, manages TLS certificates, and forwards HTTP traffic to the instance.

1. In /etc/gitlab/gitlab.rb specify the following configuration:

   external_url "https://example.com" # external_url here is only for reference
   pages_external_url 'https://example.io' # Important: not a subdomain of external_url, so cannot be https://pages.example.com
   
   pages_nginx['enable'] = true
   pages_nginx['listen_port'] = 80
   pages_nginx['listen_https'] = false
   pages_nginx['redirect_http_to_https'] = true
   

2. Reconfigure GitLab.

Global settings

Below is a table of all configuration settings known to Pages in a Linux package installation, and what they do. These options can be adjusted in /etc/gitlab/gitlab.rb, and take effect after you reconfigure GitLab. Most of these settings don’t have to be configured manually unless you need more granular control over how the Pages daemon runs and serves content in your environment.

Advanced configuration

In addition to the wildcard domains, you can also have the option to configure GitLab Pages to work with custom domains. Again, there are two options here: support custom domains with and without TLS certificates. The easiest setup is that without TLS certificates. In either case, you need a secondary IP. If you have IPv6 as well as IPv4 addresses, you can use them both.

Custom domains

Requirements:

• Wildcard DNS setup
• Secondary IP

URL scheme: http://<namespace>.example.io/<project_slug> and http://custom-domain.com

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 are supported, but no TLS.

1. In /etc/gitlab/gitlab.rb specify the following configuration:

   external_url "http://example.com" # external_url here is only for reference
   pages_external_url 'http://example.io' # Important: not a subdomain of external_url, so cannot be http://pages.example.com
   nginx['listen_addresses'] = ['192.0.2.1'] # The primary IP of the GitLab instance
   pages_nginx['enable'] = false
   gitlab_pages['external_http'] = ['192.0.2.2:80', '[2001:db8::2]:80'] # The secondary IPs for the GitLab Pages daemon
   

   If you don’t have IPv6, you can omit the IPv6 address.

2. Reconfigure GitLab.

Custom domains with TLS support

Requirements:

• Wildcard DNS setup
• TLS certificate. Can be either Wildcard, or any other type meeting the requirements.
• Secondary IP

URL scheme: https://<namespace>.example.io/<project_slug> and https://custom-domain.com

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. Place the wildcard LTS certificate for *.example.io and the key inside /etc/gitlab/ssl.

2. In /etc/gitlab/gitlab.rb specify the following configuration:

   external_url "https://example.com" # external_url here is only for reference
   pages_external_url 'https://example.io' # Important: not a subdomain of external_url, so cannot be https://pages.example.com
   nginx['listen_addresses'] = ['192.0.2.1'] # The primary IP of the GitLab instance
   pages_nginx['enable'] = false
   gitlab_pages['external_http'] = ['192.0.2.2:80', '[2001:db8::2]:80'] # The secondary IPs for the GitLab Pages daemon
   gitlab_pages['external_https'] = ['192.0.2.2:443', '[2001:db8::2]:443'] # The secondary IPs for the GitLab Pages daemon
   # Redirect pages from HTTP to HTTPS
   gitlab_pages['redirect_http'] = true
   

   If you don’t have IPv6, you can omit the IPv6 address.

3. If you haven’t named your certificate example.io.crt and your key example.io.key, then you need to also add the full paths as shown below:

   gitlab_pages['cert'] = "/etc/gitlab/ssl/example.io.crt"
   gitlab_pages['cert_key'] = "/etc/gitlab/ssl/example.io.key"
   

4. Reconfigure GitLab.
5. If you’re using Pages Access Control, update the redirect URI in the GitLab Pages System OAuth application to use the HTTPS protocol.

Custom domain verification

To prevent malicious users from hijacking domains that don’t belong to them, GitLab supports custom domain verification. When adding a custom domain, users are required to prove they own it by adding a GitLab-controlled verification code to the DNS records for that domain.

If your user base is private or otherwise trusted, you can disable the verification requirement:

1. On the left sidebar, select Search or go to.
2. Select Admin Area.
3. On the left sidebar, select Settings > Preferences.
4. Expand Pages.
5. Clear the Require users to prove ownership of custom domains checkbox. This setting is enabled by default.

Let’s Encrypt integration

GitLab Pages’ Let’s Encrypt integration allows users to add Let’s Encrypt SSL certificates for GitLab Pages sites served under a custom domain.

To enable it:

1. Choose an email address on which you want to receive notifications about expiring domains.
2. On the left sidebar, select Search or go to.
3. Select Admin Area.
4. On the left sidebar, select Settings > Preferences.
5. Expand Pages.
6. Enter the email address for receiving notifications and accept Let’s Encrypt’s Terms of Service.
7. Select Save changes.

Access control

GitLab Pages access control can be configured per-project, and allows access to a Pages site to be controlled based on a user’s membership to that project.

Access control works by registering the Pages daemon as an OAuth application with GitLab. Whenever a request to access a private Pages site is made by an unauthenticated user, the Pages daemon redirects the user to GitLab. If authentication is successful, the user is redirected back to Pages with a token, which is persisted in a cookie. The cookies are signed with a secret key, so tampering can be detected.

Each request to view a resource in a private site is authenticated by Pages using that token. For each request it receives, it makes a request to the GitLab API to check that the user is authorized to read that site.

Pages access control is disabled by default. To enable it:

1. Enable it in /etc/gitlab/gitlab.rb:

   gitlab_pages['access_control'] = true
   

2. Reconfigure GitLab.
3. Users can now configure it in their projects’ settings.

Using Pages with reduced authentication scope

By default, the Pages daemon uses the api scope to authenticate. You can configure this. For example, this reduces the scope to read_api in /etc/gitlab/gitlab.rb:

gitlab_pages['auth_scope'] = 'read_api'

The scope to use for authentication must match the GitLab Pages OAuth application settings. Users of pre-existing applications must modify the GitLab Pages OAuth application. Follow these steps to do this:

1. Enable access control.
2. On the left sidebar, select Search or go to.
3. Select Admin Area.
4. On the left sidebar, select Applications.
5. Expand GitLab Pages.
6. Clear the api scope’s checkbox and select the desired scope’s checkbox (for example, read_api).
7. Select Save changes.

Disable public access to all Pages sites

You can enforce Access Control for all GitLab Pages websites hosted on your GitLab instance. By doing so, only authenticated users have access to them. This setting overrides Access Control set by users in individual projects.

This can be helpful to restrict information published with Pages websites to the users of your instance only. To do that:

1. On the left sidebar, select Search or go to.
2. Select Admin Area.
3. On the left sidebar, select Settings > Preferences.
4. Expand Pages.
5. Select the Disable public access to Pages sites checkbox.
6. Select Save changes.

Running behind a proxy

Like the rest of GitLab, Pages can be used in those environments where external internet connectivity is gated by a proxy. To use a proxy for GitLab Pages:

1. Configure in /etc/gitlab/gitlab.rb:

   gitlab_pages['env']['http_proxy'] = 'http://example:8080'
   

2. Reconfigure GitLab for the changes to take effect.

Using a custom Certificate Authority (CA)

When using certificates issued by a custom CA, Access Control and the online view of HTML job artifacts fails to work if the custom CA is not recognized.

This usually results in this error: Post /oauth/token: x509: certificate signed by unknown authority.

For Linux package installations, this is fixed by installing a custom CA.

For self-compiled installations, this can be fixed by installing the custom Certificate Authority (CA) in the system certificate store.

ZIP serving and cache configuration

GitLab Pages can serve content from ZIP archives through object storage (an issue exists for supporting disk storage as well). It uses an in-memory cache to increase the performance when serving content from a ZIP archive. You can modify the cache behavior by changing the following configuration flags.

ZIP cache refresh example

Archives are refreshed in the cache (extending the time they are held in memory) if they’re accessed before zip_cache_expiration, and the time left before expiring is less than or equal to zip_cache_refresh. For example, if archive.zip is accessed at time 0s, it expires in 60s (the default for zip_cache_expiration). In the example below, if the archive is opened again after 15s it is not refreshed because the time left for expiry (45s) is greater than zip_cache_refresh (default 30s). However, if the archive is accessed again after 45s (from the first time it was opened) it’s refreshed. This extends the time the archive remains in memory from 45s + zip_cache_expiration (60s), for a total of 105s.

After an archive reaches zip_cache_expiration, it’s marked as expired and removed on the next zip_cache_cleanup interval.

HTTP Strict Transport Security (HSTS) support

HTTP Strict Transport Security (HSTS) can be enabled through the gitlab_pages['headers'] configuration option. HSTS informs browsers that the website they are visiting should always provide its content over HTTPS to ensure that attackers cannot force subsequent connections to happen unencrypted. It can also improve loading speed of pages as it prevents browsers from attempting to connect over an unencrypted HTTP channel before being redirected to HTTPS.

gitlab_pages['headers'] = ['Strict-Transport-Security: max-age=63072000']

Pages project redirects limits

GitLab Pages comes with a set of default limits for the _redirects file to minimize the impact on performance. You can configure these limits if you’d like to increase or decrease the limits.

gitlab_pages['redirects_max_config_size'] = 131072
gitlab_pages['redirects_max_path_segments'] = 50
gitlab_pages['redirects_max_rule_count'] = 2000

Use environment variables

You can pass an environment variable to the Pages daemon (for example, to enable or disable a feature flag).

To disable the configurable directory feature:

1. Edit /etc/gitlab/gitlab.rb:

   gitlab_pages['env'] = {
     'FF_CONFIGURABLE_ROOT_DIR' => "false"
   }
   

2. Save the file and reconfigure GitLab:

   sudo gitlab-ctl reconfigure
   

Activate verbose logging for daemon

Follow the steps below to configure verbose logging of GitLab Pages daemon.

1. By default the daemon only logs with INFO level. If you wish to make it log events with level DEBUG you must configure this in /etc/gitlab/gitlab.rb:

   gitlab_pages['log_verbose'] = true
   

2. Reconfigure GitLab.

Propagating the correlation ID

Setting the propagate_correlation_id to true allows installations behind a reverse proxy to generate and set a correlation ID to requests sent to GitLab Pages. When a reverse proxy sets the header value X-Request-ID, the value propagates in the request chain. Users can find the correlation ID in the logs.

To enable the propagation of the correlation ID:

1. Set the parameter to true in /etc/gitlab/gitlab.rb:

   gitlab_pages['propagate_correlation_id'] = true
   

2. Reconfigure GitLab.

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:

   gitlab_rails['pages_path'] = "/mnt/storage/pages"
   

2. Reconfigure GitLab.

Configure listener for reverse proxy requests

Follow the steps below to configure the proxy listener of GitLab Pages.

1. By default the listener is configured to listen for requests on localhost:8090.

   If you wish to disable it you must configure this in /etc/gitlab/gitlab.rb:

   gitlab_pages['listen_proxy'] = nil
   

   If you wish to make it listen on a different port you must configure this also in /etc/gitlab/gitlab.rb:

   gitlab_pages['listen_proxy'] = "localhost:10080"
   

2. Reconfigure GitLab.

Set global maximum size of each GitLab Pages site

Prerequisite:

• You must have administrator access to the instance.

To set the global maximum pages size for a project:

1. On the left sidebar, select Search or go to.
2. Select Admin Area.
3. On the left sidebar, select Settings > Preferences.
4. Expand Pages.
5. In Maximum size of pages, enter a value. The default is 100.
6. Select Save changes.

Set maximum size of each GitLab Pages site in a group

Prerequisite:

• You must have administrator access to the instance.

To set the maximum size of each GitLab Pages site in a group, overriding the inherited setting:

1. On the left sidebar, select Search or go to and find your group.
2. On the left sidebar, select Settings > General.
3. Expand Pages.
4. Enter a value under Maximum size in MB.
5. Select Save changes.

Set maximum size of GitLab Pages site in a project

1. On the left sidebar, select Search or go to and find your project.
2. On the left sidebar, select Deploy > Pages.
3. In Maximum size of pages, enter the size in MB.
4. Select Save changes.

Set maximum number of GitLab Pages custom domains for a project

Prerequisite:

• You must have administrator access to the instance.

To set the maximum number of GitLab Pages custom domains for a project:

1. On the left sidebar, select Search or go to.
2. Select Admin Area.
3. On the left sidebar, select Settings > Preferences, and expand Pages.
4. Enter a value for Maximum number of custom domains per project. Use 0 for unlimited domains.
5. Select Save changes.

Set maximum number of files per GitLab Pages website

The total number of file entries (including directories and symlinks) is limited to 200,000 per GitLab Pages website.

You can update the limit in your self-managed instance using the GitLab Rails console.

For more information, see GitLab application limits.

Running GitLab Pages on a separate server

You can run the GitLab Pages daemon on a separate server to decrease the load on your main application server. This configuration does not support mutual TLS (mTLS). See the corresponding feature proposal for more information.

To configure GitLab Pages on a separate server:

1. Create a backup of the secrets file on the GitLab server:

   cp /etc/gitlab/gitlab-secrets.json /etc/gitlab/gitlab-secrets.json.bak
   

2. On the GitLab server, to enable Pages, add the following to /etc/gitlab/gitlab.rb:

   pages_external_url "http://<pages_server_URL>"
   

3. Optionally, to enable access control, add the following to /etc/gitlab/gitlab.rb:

   gitlab_pages['access_control'] = true
   

4. Configure the object storage and migrate pages data to it.

5. Reconfigure the GitLab server for the changes to take effect. The gitlab-secrets.json file is now updated with the new configuration.

6. Set up a new server. This becomes the Pages server.

7. On the Pages server, install GitLab by using the Linux package and modify /etc/gitlab/gitlab.rb to include:

   roles ['pages_role']
   
   pages_external_url "http://<pages_server_URL>"
   
   gitlab_pages['gitlab_server'] = 'http://<gitlab_server_IP_or_URL>'
   
   ## If access control was enabled on step 3
   gitlab_pages['access_control'] = true
   

8. If you have custom UID/GID settings on the GitLab server, add them to the Pages server /etc/gitlab/gitlab.rb as well, otherwise running a gitlab-ctl reconfigure on the GitLab server can change file ownership and cause Pages requests to fail.

9. Create a backup of the secrets file on the Pages server:

   cp /etc/gitlab/gitlab-secrets.json /etc/gitlab/gitlab-secrets.json.bak
   

10. Copy the /etc/gitlab/gitlab-secrets.json file from the GitLab server to the Pages server.

    # On the GitLab server
    cp /etc/gitlab/gitlab-secrets.json /mnt/pages/gitlab-secrets.json
    
    # On the Pages server
    mv /var/opt/gitlab/gitlab-rails/shared/pages/gitlab-secrets.json /etc/gitlab/gitlab-secrets.json
    

11. Reconfigure the Pages server for the changes to take effect.

12. On the GitLab server, make the following changes to /etc/gitlab/gitlab.rb:

    pages_external_url "http://<pages_server_URL>"
    gitlab_pages['enable'] = false
    pages_nginx['enable'] = false
    

13. Reconfigure the GitLab server for the changes to take effect.

It’s possible to run GitLab Pages on multiple servers if you wish to distribute the load. You can do this through standard load balancing practices such as configuring your DNS server to return multiple IPs for your Pages server, or configuring a load balancer to work at the IP level. If you wish to set up GitLab Pages on multiple servers, perform the above procedure for each Pages server.

Domain source configuration

When GitLab Pages daemon serves pages requests it firstly needs to identify which project should be used to serve the requested URL and how its content is stored.

Before GitLab 13.3, all pages content was extracted to the special shared directory, and each project had a special configuration file. The Pages daemon was reading these configuration files and storing their content in memory.

This approach had several disadvantages and was replaced with GitLab Pages using the internal GitLab API every time a new domain is requested. The domain information is also cached by the Pages daemon to speed up subsequent requests.

Starting from GitLab 14.0 GitLab Pages uses API by default and fails to start if it can’t connect to it. For common issues, see troubleshooting.

For more details see this blog post.

GitLab API cache configuration

API-based configuration uses a caching mechanism to improve performance and reliability of serving Pages. The cache behavior can be modified by changing the cache settings, however, the recommended values are set for you and should only be modified if needed. Incorrect configuration of these values may result in intermittent or persistent errors, or the Pages Daemon serving old content.

Examples:

• Increasing gitlab_cache_expiry allows items to exist in the cache longer. This setting might be useful if the communication between GitLab Pages and GitLab Rails is not stable.

• Increasing gitlab_cache_refresh reduces the frequency at which GitLab Pages requests a domain’s configuration from GitLab Rails. This setting might be useful GitLab Pages generates too many requests to GitLab API and content does not change frequently.

• Decreasing gitlab_cache_cleanup removes expired items from the cache more frequently, reducing the memory usage of your Pages node.

• Decreasing gitlab_retrieval_timeout allows you to stop the request to GitLab Rails more quickly. Increasing it allows more time to receive a response from the API, useful in slow networking environments.

• Decreasing gitlab_retrieval_interval makes requests to the API more frequently, only when there is an error response from the API, for example a connection timeout.

• Decreasing gitlab_retrieval_retries reduces the number of times a domain’s configuration is tried to be resolved automatically before reporting an error.

Object storage settings

The following object storage settings are:

• Nested under pages: and then object_store: on self-compiled installations.
• Prefixed by pages_object_store_ on Linux package installations.

S3-compatible connection settings

In GitLab 13.2 and later, you should use the consolidated object storage settings. This section describes the earlier configuration format.

See the available connection settings for different providers.

Migrate Pages deployments to object storage

Existing Pages deployment objects (zip archives) can be stored in either:

• Local storage
• Object storage

Migrate your existing Pages deployments from local storage to object storage:

sudo gitlab-rake gitlab:pages:deployments:migrate_to_object_storage

You can track progress and verify that all Pages deployments migrated successfully using the PostgreSQL console:

• sudo gitlab-rails dbconsole for Linux package installations running GitLab 14.1 and earlier.
• sudo gitlab-rails dbconsole --database main for Linux package installations running 14.2 and later.
• sudo -u git -H psql -d gitlabhq_production for self-compiled installations.

Verify objectstg below (where store=2) has count of all Pages deployments:

gitlabhq_production=# SELECT count(*) AS total, sum(case when file_store = '1' then 1 else 0 end) AS filesystem, sum(case when file_store = '2' then 1 else 0 end) AS objectstg FROM pages_deployments;

total | filesystem | objectstg
------+------------+-----------
   10 |          0 |        10

After verifying everything is working correctly, disable Pages local storage.

Rolling Pages deployments back to local storage

After the migration to object storage is performed, you can choose to move your Pages deployments back to local storage:

sudo gitlab-rake gitlab:pages:deployments:migrate_to_local

Disable Pages local storage

If you use object storage, you can disable local storage to avoid unnecessary disk usage/writes:

1. Edit /etc/gitlab/gitlab.rb:

   gitlab_rails['pages_local_store_enabled'] = false
   

2. Reconfigure GitLab for the changes to take effect.

ZIP storage

In GitLab 14.0 the underlying storage format of GitLab Pages changed from files stored directly in disk to a single ZIP archive per project.

These ZIP archives can be stored either locally on disk storage or on object storage if it is configured.

Starting from GitLab 13.5 ZIP archives are stored every time pages site is updated.

Backup

GitLab Pages are part of the regular backup, so there is no separate backup to configure.

Security

You should strongly consider running GitLab Pages under a different hostname than GitLab to prevent XSS attacks.

Rate limits

You can enforce rate limits to help minimize the risk of a Denial of Service (DoS) attack. GitLab Pages uses a token bucket algorithm to enforce rate limiting. By default, requests or TLS connections that exceed the specified limits are reported but not rejected.

GitLab Pages supports the following types of rate limiting:

• Per source_ip. It limits how many requests or TLS connections are allowed from the single client IP address.
• Per domain. It limits how many requests or TLS connections are allowed per domain hosted on GitLab Pages. It can be a custom domain like example.com, or group domain like group.gitlab.io.

HTTP request-based rate limits are enforced using the following:

• rate_limit_source_ip: Set the maximum threshold in number of requests per client IP per second. Set to 0 to disable this feature.
• rate_limit_source_ip_burst: Sets the maximum threshold of number of requests allowed in an initial outburst of requests per client IP. For example, when you load a web page that loads a number of resources at the same time.
• rate_limit_domain: Set the maximum threshold in number of requests per hosted pages domain per second. Set to 0 to disable this feature.
• rate_limit_domain_burst: Sets the maximum threshold of number of requests allowed in an initial outburst of requests per hosted pages domain.

TLS connection-based rate limits are enforced using the following:

• rate_limit_tls_source_ip: Set the maximum threshold in number of TLS connections per client IP per second. Set to 0 to disable this feature.
• rate_limit_tls_source_ip_burst: Sets the maximum threshold of number of TLS connections allowed in an initial outburst of TLS connections per client IP. For example, when you load a web page from different web browsers at the same time.
• rate_limit_tls_domain: Set the maximum threshold in number of TLS connections per hosted pages domain per second. Set to 0 to disable this feature.
• rate_limit_tls_domain_burst: Sets the maximum threshold of number of TLS connections allowed in an initial outburst of TLS connections per hosted pages domain.

Enable HTTP requests rate limits by source-IP

1. Set rate limits in /etc/gitlab/gitlab.rb:

   gitlab_pages['rate_limit_source_ip'] = 20.0
   gitlab_pages['rate_limit_source_ip_burst'] = 600
   

2. Reconfigure GitLab.

Enable HTTP requests rate limits by domain

1. Set rate limits in /etc/gitlab/gitlab.rb:

   gitlab_pages['rate_limit_domain'] = 1000
   gitlab_pages['rate_limit_domain_burst'] = 5000
   

2. Reconfigure GitLab.

Enable TLS connections rate limits by source-IP

1. Set rate limits in /etc/gitlab/gitlab.rb:

   gitlab_pages['rate_limit_tls_source_ip'] = 20.0
   gitlab_pages['rate_limit_tls_source_ip_burst'] = 600
   

2. Reconfigure GitLab.

Enable TLS connections rate limits by domain

1. Set rate limits in /etc/gitlab/gitlab.rb:

   gitlab_pages['rate_limit_tls_domain'] = 1000
   gitlab_pages['rate_limit_tls_domain_burst'] = 5000
   

2. Reconfigure GitLab.
