OpenAPI Generator CI/CD — Integrating Code Generation into Continuous Integration and Delivery Pipelines

In this tutorial, you will learn about OpenAPI Generator CI/CD. We cover key concepts, practical examples, and best practices to help you master this topic.

OpenAPI Generator CI/CD integrates Code Generation into automated pipelines with spec validation, conditional generation based on spec changes, parallel multi-language generation, and quality gates that block publishing on test failures.

What You'll Learn

• CI/CD pipeline design for code generation
• Conditional generation with spec change detection
• Parallel generation for multiple languages
• Caching generated output across runs
• Quality gates and rollback

Why It Matters

Manual generation doesn't scale across multiple specs, languages, and teams. CI/CD integration ensures every spec change produces tested, versioned SDKs automatically. DodaTech's CI pipeline processes 15 specs × 8 languages = 120 generation jobs daily.
