How to Integrate Terraform and YAML into a Practical CI/CD Pipeline

A technical guide published on DEV Community outlines best practices for integrating Terraform and YAML configurations into CI/CD pipelines for automated infrastructure deployment. The article recommends a clearly separated repository structure, distinguishing generic Terraform code from environment-specific YAML configuration files across dev, staging, and production environments. It details essential pipeline stages — including validation, planning, and application — using GitHub Actions as a reference, while noting the principles apply to any CI/CD platform. The guide also covers branching strategies, modular Terraform design, and hierarchical YAML management to enable consistent and reliable infrastructure provisioning. Security considerations and reusable module patterns are highlighted as key elements for production-grade Infrastructure as Code workflows.
