# Host the GitLab product documentation **(FREE SELF)**
If you are not able to access the GitLab product documentation at `docs.gitlab.com`,
you can host the documentation yourself instead.
Prerequisites:
- The version of the product documentation site must be the same as the version of
your GitLab installation.
## Documentation self-hosting options
To host the GitLab product documentation, you can use:
- A Docker container
- GitLab Pages
- Your own web server
After you create a website by using one of these methods, redirect the UI links
in the product to point to your website.
NOTE:
The website you create must be hosted under a subdirectory that matches
your installed GitLab version (for example, `14.5/`). The
[Docker images](https://gitlab.com/gitlab-org/gitlab-docs/container_registry/631635)
use this version by default.
The following examples use GitLab 14.5.
### Self-host the product documentation with Docker
The documentation website is served under the port `4000` inside the container.
In the following example, we expose this on the host under the same port.
Make sure you either:
- Allow port `4000` in your firewall.
- Use a different port. In following examples, replace the leftmost `4000` with a different port number.
To run the GitLab product documentation website in a Docker container:
1. On the server where you host GitLab, or on any other server that your GitLab instance
can communicate with:
- If you use plain Docker, run:
```shell
docker run --detach --name gitlab_docs -it --rm -p 4000:4000 registry.gitlab.com/gitlab-org/gitlab-docs:14.5
```
- If you host your GitLab instance using
[Docker compose](../install/docker.md#install-gitlab-using-docker-compose),
add the following to your existing `docker-compose.yaml`:
```yaml
version: '3.6'
services:
gitlab_docs:
image: registry.gitlab.com/gitlab-org/gitlab-docs:14.5
hostname: 'https://docs.gitlab.example.com:4000'
ports:
- '4000:4000'
```
Then, pull the changes:
```shell
docker-compose up -d
```
1. Visit `http://0.0.0.0:4000` to view the documentation website and verify that
it works.
1. [Redirect the help links to the new Docs site](#redirect-the-help-links-to-the-new-docs-site).
### Self-host the product documentation with GitLab Pages
You can use GitLab Pages to host the GitLab product documentation.
Prerequisite:
- Ensure the Pages site URL does not use a subfolder. Because of the way the docs
site is pre-compiled, the CSS and JavaScript files are relative to the
main domain or subdomain. For example, URLs like `https://example.com/docs/`
are not supported.
To host the product documentation site with GitLab Pages:
1. [Create a blank project](../user/project/index.md#create-a-blank-project).
1. Create a new or edit your existing `.gitlab-ci.yml` file, and add the following
`pages` job, while ensuring the version is the same as your GitLab installation:
```yaml
image: registry.gitlab.com/gitlab-org/gitlab-docs:14.5
pages:
script:
- mkdir public
- cp -a /usr/share/nginx/html/* public/
artifacts:
paths:
- public
```
1. Optional. Set the GitLab Pages domain name. Depending on the type of the
GitLab Pages website, you have two options:
| Type of website | [Default domain](../user/project/pages/getting_started_part_one.md#gitlab-pages-default-domain-names) | [Custom domain](../user/project/pages/custom_domains_ssl_tls_certification/index.md) |
|-------------------------|----------------|---------------|
| [Project website](../user/project/pages/getting_started_part_one.md#project-website-examples) | Not supported | Supported |
| [User or group website](../user/project/pages/getting_started_part_one.md#user-and-group-website-examples) | Supported | Supported |
1. [Redirect the help links to the new Docs site](#redirect-the-help-links-to-the-new-docs-site).
### Self-host the product documentation on your own web server
Because the product documentation site is static, you can take the contents of
`/usr/share/nginx/html` from inside the container, and use your own web server to host
the docs wherever you want.
The `html` directory should be served as is and it has the following structure:
```plaintext
├── 14.5/
├── index.html
```
In this example:
- `14.5/` is the directory where the documentation is hosted.
- `index.html` is a simple HTML file that redirects to the directory containing the documentation. In this
case, `14.5/`.
To extract the HTML files of the Docs site:
1. Create the container that holds the HTML files of the documentation website:
```shell
docker create -it --name gitlab_docs registry.gitlab.com/gitlab-org/gitlab-docs:14.5
```
1. Copy the website under `/srv/gitlab/`:
```shell
docker cp gitlab-docs:/usr/share/nginx/html /srv/gitlab/
```
You end up with a `/srv/gitlab/html/` directory that holds the documentation website.
1. Remove the container:
```shell
docker rm -f gitlab_docs
```
1. Point your web server to serve the contents of `/srv/gitlab/html/`.
1. [Redirect the help links to the new Docs site](#redirect-the-help-links-to-the-new-docs-site).
## Redirect the `/help` links to the new Docs site
After your local product documentation site is running,
[redirect the help links](../user/admin_area/settings/help_page.md#redirect-help-pages)
in the GitLab application to your local site, by using the fully qualified domain
name as the docs URL. For example, if you used the
[Docker method](#self-host-the-product-documentation-with-docker), enter `http://0.0.0.0:4000`.
You don't need to append the version. GitLab detects it and appends it to
documentation URL requests as needed. For example, if your GitLab version is
14.5:
- The GitLab Docs URL becomes `http://0.0.0.0:4000/14.5/`.
- The link in GitLab displays as `<instance_url>/help/user/admin_area/settings/help_page#destination-requirements`.
- When you select the link, you are redirected to
`http://0.0.0.0:4000/14.5/ee/user/admin_area/settings/help_page/#destination-requirements`.
To test the setting, in GitLab, select a **Learn more** link. For example:
1. On the top bar, in the upper-right corner, select your avatar.
1. Select **Preferences**.
1. In the **Syntax highlighting theme** section, select **Learn more**.
## Upgrade the product documentation to a later version
Upgrading the Docs site to a later version requires downloading the newer Docker image tag.
### Upgrade using Docker
To upgrade to a later version [using Docker](#self-host-the-product-documentation-with-docker):
- If you use Docker:
1. Stop the running container:
```shell
sudo docker stop gitlab_docs
```
1. Remove the existing container:
```shell
sudo docker rm gitlab_docs
```
1. Pull the new image. For example, 14.6:
```shell
docker run --detach --name gitlab_docs -it --rm -p 4000:4000 registry.gitlab.com/gitlab-org/gitlab-docs:14.6
```
- If you use Docker Compose:
1. Change the version in `docker-compose.yaml`, for example 14.6:
```yaml
version: '3.6'
services:
gitlab_docs:
image: registry.gitlab.com/gitlab-org/gitlab-docs:14.6
hostname: 'https://docs.gitlab.example.com:4000'
ports:
- '4000:4000'
```
1. Pull the changes:
```shell
docker-compose up -d
```
### Upgrade using GitLab Pages
To upgrade to a later version [using GitLab Pages](#self-host-the-product-documentation-with-gitlab-pages):
1. Edit your existing `.gitlab-ci.yml` file, and replace the `image` version number:
```yaml
image: registry.gitlab.com/gitlab-org/gitlab-docs:14.5
```
1. Commit the changes, push, and GitLab Pages pulls the new Docs site version.
### Upgrade using your own web-server
To upgrade to a later version [using your own web-server](#self-host-the-product-documentation-on-your-own-web-server):
1. Copy the HTML files of the Docs site:
```shell
docker create -it --name gitlab_docs registry.gitlab.com/gitlab-org/gitlab-docs:14.6
docker cp gitlab_docs:/usr/share/nginx/html /srv/gitlab/
docker rm -f gitlab_docs
```
1. Optional. Remove the old site:
```shell
rm -r /srv/gitlab/html/14.5/
```
## Known issues
If you self-host the product documentation:
- By default, the landing page redirects to the
respective version (for example, `/14.5/`). This causes the landing page <https://docs.gitlab.com> to not be displayed.
