To familiarize yourself with GitLab Pages first: - Read an [introduction to GitLab Pages](index.md). - Learn [how to get started with Pages](index.md#getting-started). - Learn how to enable GitLab Pages across your GitLab instance on the [administrator documentation](../../../administration/pages/index.md). ## GitLab Pages requirements In brief, this is what you need to upload your website in GitLab Pages: 1. Domain of the instance: domain name that is used for GitLab Pages (ask your administrator). 1. GitLab CI/CD: a `.gitlab-ci.yml` file with a specific job named [`pages`](../../../ci/yaml/index.md#pages) in the root directory of your repository. 1. A directory called `public` in your site's repository containing the content to be published. 1. GitLab Runner enabled for the project. ## GitLab Pages on GitLab.com If you are using [GitLab Pages on GitLab.com](#gitlab-pages-on-gitlabcom) to host your website, then: - The domain name for GitLab Pages on GitLab.com is `gitlab.io`. - Custom domains and TLS support are enabled. - Shared runners are enabled by default, provided for free and can be used to build your website. If you want you can still bring your own runner. ## Example projects Visit the [GitLab Pages group](https://gitlab.com/groups/pages) for a complete list of example projects. Contributions are very welcome. ## Custom error codes pages You can provide your own `403` and `404` error pages by creating `403.html` and `404.html` files in the root of the `public/` directory. Usually this is the root directory of your project, but that may differ depending on your static generator configuration. If the case of `404.html`, there are different scenarios. For example: - If you use project Pages (served under `/projectname/`) and try to access `/projectname/non/existing_file`, GitLab Pages tries to serve first `/projectname/404.html`, and then `/404.html`. - If you use user or group Pages (served under `/`) and try to access `/non/existing_file` GitLab Pages tries to serve `/404.html`. - If you use a custom domain and try to access `/non/existing_file`, GitLab Pages tries to serve only `/404.html`. ## Redirects in GitLab Pages You can configure redirects for your site using a `_redirects` file. For more information, see [Create redirects for GitLab Pages](redirects.md). ## Remove your pages To remove your pages: 1. On the top bar, select **Main menu > Projects** and find your project. 1. On the left sidebar, select **Settings > Pages**. If this path is not visible, select **Deployments > Pages**. [This location is part of an experiment](index.md#menu-position-test). 1. Select **Remove pages**. ## Subdomains of subdomains When using Pages under the top-level domain of a GitLab instance (`*.example.io`), you can't use HTTPS with subdomains of subdomains. If your namespace or group name contains a dot (for example, `foo.bar`) the domain `https://foo.bar.example.io` does **not** work. This limitation is because of the [HTTP Over TLS protocol](https://www.rfc-editor.org/rfc/rfc2818#section-3.1). HTTP pages work as long as you don't redirect HTTP to HTTPS. ## GitLab Pages in projects and groups You must host your GitLab Pages website in a project. This project can be [private, internal, or public](../../../user/public_access.md) and belong to a [group](../../group/index.md) or [subgroup](../../group/subgroups/index.md). For [group websites](../../project/pages/getting_started_part_one.md#user-and-group-website-examples), the group must be at the top level and not a subgroup. For [project websites](../../project/pages/getting_started_part_one.md#project-website-examples), you can create your project first and access it under `http(s)://namespace.example.io/projectname`. ## Specific configuration options for Pages Learn how to set up GitLab CI/CD for specific use cases. ### `.gitlab-ci.yml` for plain HTML websites Supposed your repository contained the following files: ```plaintext ├── index.html ├── css │ └── main.css └── js └── main.js ``` Then the `.gitlab-ci.yml` example below moves all files from the root directory of the project to the `public/` directory. The `.public` workaround is so `cp` doesn't also copy `public/` to itself in an infinite loop: ```yaml pages: script: - mkdir .public - cp -r * .public - mv .public public artifacts: paths: - public only: - main ``` ### `.gitlab-ci.yml` for a static site generator See this document for a [step-by-step guide](getting_started/pages_from_scratch.md). ### `.gitlab-ci.yml` for a repository with code Remember that GitLab Pages are by default branch/tag agnostic and their deployment relies solely on what you specify in `.gitlab-ci.yml`. You can limit the `pages` job with the [`only` parameter](../../../ci/yaml/index.md#only--except), whenever a new commit is pushed to a branch used specifically for your pages. That way, you can have your project's code in the `main` branch and use an orphan branch (let's name it `pages`) to host your static generator site. You can create a new empty branch like this: ```shell git checkout --orphan pages ``` The first commit made on this new branch has no parents and is the root of a new history totally disconnected from all the other branches and commits. Push the source files of your static generator in the `pages` branch. Below is a copy of `.gitlab-ci.yml` where the most significant line is the last one, specifying to execute everything in the `pages` branch: ```yaml image: ruby:2.6 pages: script: - gem install jekyll - jekyll build -d public/ artifacts: paths: - public only: - pages ``` See an example that has different files in the [`main` branch](https://gitlab.com/pages/jekyll-branched/tree/main) and the source files for Jekyll are in a [`pages` branch](https://gitlab.com/pages/jekyll-branched/tree/pages) which also includes `.gitlab-ci.yml`. ### Serving compressed assets Most modern browsers support downloading files in a compressed format. This speeds up downloads by reducing the size of files. Before serving an uncompressed file, Pages checks if the same file exists with a `.br` or `.gz` extension. If it does, and the browser supports receiving compressed files, it serves that version instead of the uncompressed one. To take advantage of this feature, the artifact you upload to the Pages should have this structure: ```plaintext public/ ├─┬ index.html │ | index.html.br │ └ index.html.gz │ ├── css/ │ └─┬ main.css │ | main.css.br │ └ main.css.gz │ └── js/ └─┬ main.js | main.js.br └ main.js.gz ``` This can be achieved by including a `script:` command like this in your `.gitlab-ci.yml` pages job: ```yaml pages: # Other directives script: # Build the public/ directory first - find public -type f -regex '.*\.\(htm\|html\|txt\|text\|js\|css\)$' -exec gzip -f -k {} \; - find public -type f -regex '.*\.\(htm\|html\|txt\|text\|js\|css\)$' -exec brotli -f -k {} \; ``` By pre-compressing the files and including both versions in the artifact, Pages can serve requests for both compressed and uncompressed content without needing to compress files on-demand. ### Resolving ambiguous URLs GitLab Pages makes assumptions about which files to serve when receiving a request for a URL that does not include an extension. Consider a Pages site deployed with the following files: ```plaintext public/ ├── index.html ├── data.html ├── info.html ├── data/ │ └── index.html └── info/ └── details.html ``` Pages supports reaching each of these files through several different URLs. In particular, it always looks for an `index.html` file if the URL only specifies the directory. If the URL references a file that doesn't exist, but adding `.html` to the URL leads to a file that *does* exist, it's served instead. Here are some examples of what happens given the above Pages site: | URL path | HTTP response | | -------------------- | ------------- | | `/` | `200 OK`: `public/index.html` | | `/index.html` | `200 OK`: `public/index.html` | | `/index` | `200 OK`: `public/index.html` | | `/data` | `302 Found`: redirecting to `/data/` | | `/data/` | `200 OK`: `public/data/index.html` | | `/data.html` | `200 OK`: `public/data.html` | | `/info` | `302 Found`: redirecting to `/info/` | | `/info/` | `404 Not Found` Error Page | | `/info.html` | `200 OK`: `public/info.html` | | `/info/details` | `200 OK`: `public/info/details.html` | | `/info/details.html` | `200 OK`: `public/info/details.html` | When `public/data/index.html` exists, it takes priority over the `public/data.html` file for both the `/data` and `/data/` URL paths. ## Known issues For a list of known issues, see the GitLab [public issue tracker](https://gitlab.com/gitlab-org/gitlab/-/issues?label_name[]=Category%3APages). ## Troubleshooting ### 404 error when accessing a GitLab Pages site URL This problem most likely results from a missing `index.html` file in the public directory. If after deploying a Pages site a 404 is encountered, confirm that the public directory contains an `index.html` file. If the file contains a different name such as `test.html`, the Pages site can still be accessed, but the full path would be needed. For example: `https//group-name.pages.example.com/project-name/test.html`. The contents of the public directory can be confirmed by [browsing the artifacts](../../../ci/pipelines/job_artifacts.md#download-job-artifacts) from the latest pipeline. Files listed under the public directory can be accessed through the Pages URL for the project. A 404 can also be related to incorrect permissions. If [Pages Access Control](pages_access_control.md) is enabled, and a user navigates to the Pages URL and receives a 404 response, it is possible that the user does not have permission to view the site. To fix this, verify that the user is a member of the project. ### Cannot play media content on Safari Safari requires the web server to support the [Range request header](https://developer.apple.com/library/archive/documentation/AppleApplications/Reference/SafariWebContent/CreatingVideoforSafarioniPhone/CreatingVideoforSafarioniPhone.html#//apple_ref/doc/uid/TP40006514-SW6) to play your media content. For GitLab Pages to serve HTTP Range requests, you should use the following two variables in your `.gitlab-ci.yml` file: ```yaml pages: stage: deploy variables: FF_USE_FASTZIP: "true" ARTIFACT_COMPRESSION_LEVEL: "fastest" script: - echo "Deploying pages" artifacts: paths: - public environment: production ``` The `FF_USE_FASTZIP` variable enables the [feature flag](https://docs.gitlab.com/runner/configuration/feature-flags.html#available-feature-flags) which is needed for [`ARTIFACT_COMPRESSION_LEVEL`](../../../ci/runners/configure_runners.md#artifact-and-cache-settings).
