Curriculum

GitLab CI/CD Foundations & Setup

This introductory section lays the groundwork for understanding Continuous Integration and Continuous Delivery (CI/CD) principles. You will learn what GitLab CI/CD is, its fundamental benefits, and how it fits into the modern development landscape. We'll guide you through setting up your GitLab environment for CI/CD, ensuring you have a solid platform to begin building. Key concepts like the overall pipeline flow, basic job execution, and stage definitions will be clearly explained, setting the stage for more advanced topics.

Mastering `.gitlab-ci.yml` Configuration

Dive deep into the heart of GitLab CI/CD: the `.gitlab-ci.yml` file. This section focuses on the syntax, structure, and best practices for writing effective and maintainable CI/CD configurations. You will learn how to define individual jobs, group them into logical stages, manage dependencies, and use essential keywords. Through practical examples, you'll gain hands-on experience in structuring your `.gitlab-ci.yml` files to create robust and readable pipeline definitions that align with your project's needs.

Advanced Pipeline Execution with GitLab Runners

This module explores the critical role of GitLab Runners in executing your CI/CD pipelines. You will learn how Runners work, different types of Runners (shared, specific), and how to register and configure them for various execution environments. We'll also delve into advanced pipeline features such as working with artifacts, caching, services, and implementing dynamic multi-stage pipelines that respond to different conditions, enabling complex and efficient automation workflows.

Optimizing & Troubleshooting GitLab CI/CD

Elevate your CI/CD skills by understanding how to optimize and debug your pipelines. This section covers crucial best practices for organizing your CI/CD configurations, managing variables securely, and improving pipeline performance and reliability. You'll learn common pitfalls and effective strategies for debugging failing jobs, interpreting pipeline logs, and troubleshooting issues related to Runners, scripts, and environment configurations. By the end, you'll be equipped to maintain clean, efficient, and error-free GitLab CI/CD pipelines.
