You start with a blank project and create your own CI/CD configuration file, which gives instructions to a [runner](https://docs.gitlab.com/runner/). When your CI/CD [pipeline](../../../../ci/pipelines/index.md) runs, the Pages site is created. This example uses Jekyll, but other SSGs follow similar steps. You do not need to be familiar with Jekyll or SSGs to complete this tutorial. To create a GitLab Pages website: - [Step 1: Create the project files](#create-the-project-files) - [Step 2: Choose a Docker image](#choose-a-docker-image) - [Step 3: Install Jekyll](#install-jekyll) - [Step 4: Specify the `public` directory for output](#specify-the-public-directory-for-output) - [Step 5: Specify the `public` directory for artifacts](#specify-the-public-directory-for-artifacts) - [Step 6: Deploy and view your website](#deploy-and-view-your-website) ## Prerequisites You must have a [blank project](../../working_with_projects.md#create-a-blank-project) in GitLab. ## Create the project files Create three files in the root (top-level) directory: - `.gitlab-ci.yml`: A YAML file that contains the commands you want to run. For now, leave the file's contents blank. - `index.html`: An HTML file you can populate with whatever HTML content you'd like, for example: ```html Home

Hello World!

``` - [`Gemfile`](https://bundler.io/gemfile.html): A file that describes dependencies for Ruby programs. Populate it with this content: ```ruby source "https://rubygems.org" gem "jekyll" ``` ## Choose a Docker image In this example, the runner uses a [Docker image](../../../../ci/docker/using_docker_images.md) to run scripts and deploy the site. This specific Ruby image is maintained on [DockerHub](https://hub.docker.com/_/ruby). Edit your `.gitlab-ci.yml` file and add this text as the first line: ```yaml image: ruby:2.7 ``` If your SSG needs [NodeJS](https://nodejs.org/) to build, you must specify an image that contains NodeJS as part of its file system. For example, for a [Hexo](https://gitlab.com/pages/hexo) site, you can use `image: node:12.17.0`. ## Install Jekyll To run [Jekyll](https://jekyllrb.com/) locally, you must install it: 1. Open your terminal. 1. Install [Bundler](https://bundler.io/) by running `gem install bundler`. 1. Create `Gemfile.lock` by running `bundle install`. 1. Install Jekyll by running `bundle exec jekyll build`. To run Jekyll in your project, edit the `.gitlab-ci.yml` file and add the installation commands: ```yaml script: - gem install bundler - bundle install - bundle exec jekyll build ``` In addition, in the `.gitlab-ci.yml` file, each `script` is organized by a `job`. A `job` includes the scripts and settings you want to apply to that specific task. ```yaml job: script: - gem install bundler - bundle install - bundle exec jekyll build ``` For GitLab Pages, this `job` has a specific name, called `pages`. This setting tells the runner you want the job to deploy your website with GitLab Pages: ```yaml pages: script: - gem install bundler - bundle install - bundle exec jekyll build ``` ## Specify the `public` directory for output Jekyll needs to know where to generate its output. GitLab Pages only considers files in a directory called `public`. Jekyll uses a destination flag (`-d`) to specify an output directory for the built website. Add the destination to your `.gitlab-ci.yml` file: ```yaml pages: script: - gem install bundler - bundle install - bundle exec jekyll build -d public ``` ## Specify the `public` directory for artifacts Now that Jekyll has output the files to the `public` directory, the runner needs to know where to get them. The artifacts are stored in the `public` directory: ```yaml pages: script: - gem install bundler - bundle install - bundle exec jekyll build -d public artifacts: paths: - public ``` Your `.gitlab-ci.yml` file should now look like this: ```yaml image: ruby:2.7 pages: script: - gem install bundler - bundle install - bundle exec jekyll build -d public artifacts: paths: - public ``` ## Deploy and view your website After you have completed the preceding steps, deploy your website: 1. Save and commit the `.gitlab-ci.yml` file. 1. Go to **CI/CD > Pipelines** to watch the pipeline. 1. When the pipeline succeeds, go to **Settings > Pages** to view the URL where your site is now available. When this `pages` job completes successfully, a special `pages:deploy` job appears in the pipeline view. It prepares the content of the website for the GitLab Pages daemon. GitLab runs it in the background and doesn't use a runner. ## Other options for your CI/CD file If you want to do more advanced tasks, you can update your `.gitlab-ci.yml` file with [any of the available settings](../../../../ci/yaml/index.md). You can validate your `.gitlab-ci.yml` file with the [CI Lint](../../../../ci/lint.md) tool that's included with GitLab. The following topics show other examples of other options you can add to your CI/CD file. ### Deploy specific branches to a Pages site You may want to deploy to a Pages site only from specific branches. First, add a `workflow` section to force the pipeline to run only when changes are pushed to branches: ```yaml image: ruby:2.7 workflow: rules: - if: $CI_COMMIT_BRANCH pages: script: - gem install bundler - bundle install - bundle exec jekyll build -d public artifacts: paths: - public ``` Then configure the pipeline to run the job for the [default branch](../../repository/branches/default.md) (here, `main`) only. ```yaml image: ruby:2.7 workflow: rules: - if: $CI_COMMIT_BRANCH pages: script: - gem install bundler - bundle install - bundle exec jekyll build -d public artifacts: paths: - public rules: - if: $CI_COMMIT_BRANCH == "main" ``` ### Specify a stage to deploy There are three default stages for GitLab CI/CD: build, test, and deploy. If you want to test your script and check the built site before deploying to production, you can run the test exactly as it runs when you push to your [default branch](../../repository/branches/default.md) (here, `main`). To specify a stage for your job to run in, add a `stage` line to your CI file: ```yaml image: ruby:2.7 workflow: rules: - if: $CI_COMMIT_BRANCH pages: stage: deploy script: - gem install bundler - bundle install - bundle exec jekyll build -d public artifacts: paths: - public rules: - if: $CI_COMMIT_BRANCH == "main" environment: production ``` Now add another job to the CI file, telling it to test every push to every branch **except** the `main` branch: ```yaml image: ruby:2.7 workflow: rules: - if: $CI_COMMIT_BRANCH pages: stage: deploy script: - gem install bundler - bundle install - bundle exec jekyll build -d public artifacts: paths: - public rules: - if: $CI_COMMIT_BRANCH == "main" environment: production test: stage: test script: - gem install bundler - bundle install - bundle exec jekyll build -d test artifacts: paths: - test rules: - if: $CI_COMMIT_BRANCH != "main" ``` When the `test` job runs in the `test` stage, Jekyll builds the site in a directory called `test`. The job affects all branches except `main`. When you apply stages to different jobs, every job in the same stage builds in parallel. If your web application needs more than one test before being deployed, you can run all your tests at the same time. ### Remove duplicate commands To avoid duplicating the same scripts in every job, you can add them to a `before_script` section. In the example, `gem install bundler` and `bundle install` were running for both jobs, `pages` and `test`. Move these commands to a `before_script` section: ```yaml image: ruby:2.7 workflow: rules: - if: $CI_COMMIT_BRANCH before_script: - gem install bundler - bundle install pages: stage: deploy script: - bundle exec jekyll build -d public artifacts: paths: - public rules: - if: $CI_COMMIT_BRANCH == "main" environment: production test: stage: test script: - bundle exec jekyll build -d test artifacts: paths: - test rules: - if: $CI_COMMIT_BRANCH != "main" ``` ### Build faster with cached dependencies To build faster, you can cache the installation files for your project's dependencies by using the `cache` parameter. This example caches Jekyll dependencies in a `vendor` directory when you run `bundle install`: ```yaml image: ruby:2.7 workflow: rules: - if: $CI_COMMIT_BRANCH cache: paths: - vendor/ before_script: - gem install bundler - bundle install --path vendor pages: stage: deploy script: - bundle exec jekyll build -d public artifacts: paths: - public rules: - if: $CI_COMMIT_BRANCH == "main" environment: production test: stage: test script: - bundle exec jekyll build -d test artifacts: paths: - test rules: - if: $CI_COMMIT_BRANCH != "main" ``` In this case, you need to exclude the `/vendor` directory from the list of folders Jekyll builds. Otherwise, Jekyll tries to build the directory contents along with the site. In the root directory, create a file called `_config.yml` and add this content: ```yaml exclude: - vendor ``` Now GitLab CI/CD not only builds the website, but also: - Pushes with **continuous tests** to feature branches. - **Caches** dependencies installed with Bundler. - **Continuously deploys** every push to the `main` branch. ## Related topics For more information, see the following blog posts. - Use GitLab CI/CD `environments` to [deploy your web app to staging and production](https://about.gitlab.com/blog/2021/02/05/ci-deployment-and-environments/). - Learn how to run jobs [sequentially, in parallel, or build a custom pipeline](https://about.gitlab.com/blog/2016/07/29/the-basics-of-gitlab-ci/). - Learn [how to pull specific directories from different projects](https://about.gitlab.com/blog/2016/12/07/building-a-new-gitlab-docs-site-with-nanoc-gitlab-ci-and-gitlab-pages/) to deploy this website, . - Learn [how to use GitLab Pages to produce a code coverage report](https://about.gitlab.com/blog/2016/11/03/publish-code-coverage-report-with-gitlab-pages/).
