Summary of GitLab CI/CD Tutorial for Beginners

Main Ideas:

• Introduction to GitLab CI/CD, its importance in DevOps, and the benefits of using GitLab as a one-stop platform for CI/CD processes.
• Overview of CI/CD concepts, focusing on continuous integration and continuous deployment.
• Step-by-step guide on building a basic CI/CD pipeline using GitLab, including testing, building a Docker image, and deploying it to a remote server.

Key Concepts:

• CI/CD Definition: Continuous Integration and Continuous Deployment (or Delivery) involve automatically testing, building, and releasing code changes to a deployment environment.
• GitLab Architecture: Involves a GitLab server hosting the application code and multiple GitLab runners executing the pipelines.
• Pipeline Configuration: Pipelines are defined using a .GitLab-ci.yml file in the project repository, utilizing YAML syntax to configure jobs and stages.

Methodology/Instructions:

1. Setting Up GitLab CI/CD:
   • Create a .GitLab-ci.yml file in the root of your project repository.
   • Define the pipeline structure using YAML syntax.
2. Creating Jobs:
   • Job for Running Tests:
     • Name the job (e.g., run_tests).
     • Use the script attribute to specify commands (e.g., make test).
     • Ensure necessary dependencies (e.g., Python, pip, make) are available in the environment.
   • Job for Building Docker Image:
     • Create a job (e.g., build_image).
     • Use Docker commands to build and push the image to a Docker Hub private repository.
     • Authenticate using secret variables for Docker Hub credentials.
3. Implementing Stages:
   • Define stages in the .GitLab-ci.yml file to control the order of job execution (e.g., test, build, deploy).
   • Assign jobs to respective stages to ensure they run in sequence.
4. Deploying to a Server:
   • Create a deploy job (e.g., deploy).
   • Use SSH to connect to a remote server and execute Docker commands to run the application.
   • Set up secret variables for SSH keys and configure permissions appropriately.
5. Triggering the Pipeline:
   • Commit changes to the .GitLab-ci.yml file to trigger the pipeline execution automatically.
   • Monitor the pipeline execution and check logs for troubleshooting.
6. Finalizing Deployment:
   • Ensure the application is running on the specified server and accessible via the browser.
   • Clean up resources by deleting the server after use.
