Course Overview
- This concise course provides a definitive introduction to GitLab CI’s core concepts, demystifying automated software delivery within GitLab’s integrated platform.
- Understand the strategic value of CI/CD in modern development, learning how GitLab CI accelerates release cycles, ensures code quality, and fosters continuous feedback.
- Explore the declarative nature of `.gitlab-ci.yml`, treating pipelines as Infrastructure as Code. Define reproducible, version-controlled automation workflows reacting intelligently to repository changes.
- Grasp how GitLab CI orchestrates your development lifecycle, ensuring every code modification triggers consistent, automated validation, boosting developer productivity and release confidence.
Requirements / Prerequisites
- A foundational understanding of Git for version control (commits, branches, pushes) is recommended, as GitLab CI workflows are repository-driven.
- Basic familiarity with software development principles and the SDLC provides context for CI/CD’s role.
- Comfort navigating a web browser and interacting with the GitLab user interface (project creation, repository management).
- While core YAML syntax will be introduced, a cursory awareness of YAML file structure can aid comprehension.
- Access to a free GitLab.com account is essential for all hands-on exercises.
- No prior experience with CI/CD tools or advanced DevOps concepts is required; this course is a beginner-friendly entry point.
Skills Covered / Tools Used
- Advanced `.gitlab-ci.yml` Syntax: Master keywords like `rules`, `only`, `except` for precise pipeline triggering, and `variables` for dynamic configurations.
- Pipeline Efficiency & Optimization: Implement strategies to reduce execution times using `cache`, `dependencies`, and parallelizing build steps.
- Artifact Handling & Persistence: Learn to manage and persist build artifacts across jobs and stages, crucial for data flow and subsequent deployment.
- Secure Credential Management: Grasp best practices for integrating and securely utilizing environment variables and CI/CD secrets within pipelines.
- GitLab Runner Ecosystem: Gain insights into various GitLab Runner types (shared, specific, group) and their impact on job execution environments.
- Containerization for CI: Explore how Docker images provide isolated, consistent, and reproducible execution environments for jobs.
- Dynamic Pipeline Logic: Create sophisticated conditional logic allowing pipelines to adapt to scenarios like branch-specific tests or tag-based deployments.
- Key Tools: GitLab (SCM & CI/CD platform), GitLab Runners (job execution agents), and the declarative `.gitlab-ci.yml` specification.
Benefits / Outcomes
- Accelerated & Reliable Releases: Design and implement pipelines that significantly reduce release cycles, enabling faster feature delivery with increased confidence.
