• Description:
  GitLab CI/CD allows automated execution of tasks such as building, testing, or deploying code whenever you push changes to the repository. To trigger a pipeline, you must create a .gitlab-ci.yml file inside your project. This file contains pipeline instructions. In this example, we create a simple CI configuration that prints a message “GitLab CI is working!” to confirm that the pipeline is running successfully.

•  Step 1: Open your project folder
   Navigate to your local Git project directory.
•  Step 2: Create a new CI configuration file
   Create a file named .gitlab-ci.yml
   Example:
   nano .gitlab-ci.yml
•  Step 3: Add basic CI pipeline code
   Copy and paste the following:
  
   stages:
    - test
  
   hello_job:
    stage: test
    script:
     - echo "GitLab CI is working!"
  
   This creates one stage named test
   One job hello_job
   It prints a message when pipeline runs
  
   Save and exit.
•  Step 4: Add the file to Git
   Tell Git that a new file has been created.
   git add .gitlab-ci.yml
•  Step 5: Commit the change
   Commit the file with a message.
   git commit -m "Added basic GitLab CI pipeline"
•  Step 6: Push changes to GitLab
   This triggers the pipeline.
   git push
•  Step 7: Verify pipeline in GitLab
   Go to:
   GitLab → Project → CI/CD → Pipelines
  
   You should see pipeline running, and when finished:
   hello_job → Passed
   Output: “GitLab CI is working!”
