Building GitLab CI Components

Overview

GitLab CI components are reusable pipeline configuration units that can be versioned, shared, and discovered through the CI/CD Catalog. This skill guides you through creating complete, correct components following GitLab's official structure.

Core principle: Follow the GitLab documentation systematically. Components have specific requirements for directory structure, files, inputs, and CI/CD configuration that must be met for valid components.

When to Use

Use this skill when:

• Creating a new reusable CI/CD component
• Packaging existing pipeline configuration for sharing
• Publishing components to the GitLab CI/CD Catalog
• Setting up a component project structure
