Phase 7: CI/CD Pipelines for AI Code · 50 min · GitHub Actions · GitLab CI · Python

Pipeline Architecture for AI Code

Design pipelines that treat AI-generated code as untrusted by default. Every gate is a checkpoint.

Hiring signal: Engineers who can design CI/CD pipelines with multi-layer quality gates for AI code demonstrate production-grade DevOps skills.

What you will learn

Design CI/CD pipelines with multi-layer quality gates for AI-generated code
Understand the agent-cicd pattern for automated AI code verification
Compare parallel vs sequential gate execution strategies
Map quality gates from prior phases into a unified pipeline architecture

The Problem

You've learned 6 phases of testing AI-written code: TDD, static analysis, property-based testing, mutation testing, security testing, and supply chain security. Now you need to orchestrate all of these in a CI/CD pipeline. This lesson covers the architecture for designing pipelines with multi-layer quality gates for AI-generated code.
