Overview

This documentation provides a step-by-step guide on how CI/CD is deployed within the gitlab-org/gitlab-ce project. It assumes a foundational understanding of CI/CD concepts and GitLab’s features.

Current Status

As of the latest updates, if the gitlab-org/gitlab-ce project has no CI/CD setup, the project will state that CI/CD is not yet configured and will offer suggestions for implementing it.

Step-by-Step Guide to CI/CD Deployment

Step 1: Configuring .gitlab-ci.yml

To initiate CI/CD for a project in GitLab, a configuration file named .gitlab-ci.yml must be created at the root of the repository. This YAML file defines the pipelines and jobs that will execute on changes to the repo.

Example .gitlab-ci.yml

stages:          # Define the stages of the pipeline
  - build
  - test
  - deploy

build_job:      # Job to build the application
  stage: build
  script:
    - echo "Building the application..."
    - make build

test_job:       # Job to test the application
  stage: test
  script:
    - echo "Running tests..."
    - make test

deploy_job:     # Job for deployment
  stage: deploy
  script:
    - echo "Deploying the application..."
    - ./deploy.sh
  only:
    - master     # This job runs only for commits to master branch

In this configuration:

  • The pipeline comprises three stages: build, test, and deploy.
  • Each job corresponds to a stage and contains scripts that are executed in order.

Step 2: Setting Up Runners

GitLab CI/CD uses runners to execute jobs defined in the .gitlab-ci.yml file. Runners can be shared, specific, or group runners.

To set up a runner, follow these steps:

  1. Go to your project’s settings in GitLab.
  2. Navigate to the CI/CD settings.
  3. Under “Runners activated for this project,” you can register a new runner if necessary.

Registering a New Runner

You can register a new runner using the following command in the terminal:

gitlab-runner register \
  --url https://gitlab.com/ \
  --registration-token YOUR_REGISTRATION_TOKEN \
  --executor shell

Replace YOUR_REGISTRATION_TOKEN with your specific token.

Step 3: Verifying Pipeline Execution

To verify that the CI/CD pipeline is working as intended:

  1. Push code changes to your repository.
  2. Navigate to the “CI/CD” section in GitLab.
  3. Monitor the pipeline status through the pipelines page.

Pipelines initiated by commits will illustrate their status, including any jobs that failed or succeeded.

Step 4: Notifying Stakeholders

Integrating notifications can enhance communication regarding pipelines. You can configure GitLab to send notifications through various channels by modifying the settings in your project.

CI/CD Not Yet Set Up

If the gitlab-org/gitlab-ce project does not have a .gitlab-ci.yml file, the project is not configured for CI/CD. Next steps include:

  1. Creating the .gitlab-ci.yml file: Follow the example above to draft an initial configuration that fits your project’s needs.
  2. Registering a GitLab Runner: Ensure you have a runner configured and linked to your project to execute the defined CI/CD jobs.
  3. Testing the Pipeline: After configuration, push an update to test the pipeline and verify that jobs run as expected.

Conclusion

This documentation provided a detailed step-by-step guide to implementing CI/CD in the gitlab-org/gitlab-ce project. For further specifics, check official GitLab CI/CD documentation.
