Learn to replace brittle GitHub Actions YAML configurations with CUE, a powerful configuration language that brings type safety, validation, and reusability to your CI/CD pipelines. Discover how CUE combines schema and data validation to catch configuration errors before deployment, using practical examples like age constraint validation. Master the CUE toolchain by using `cue vet` to validate workflows against schemas, importing existing GitHub Actions definitions from the CUE Central Registry for instant pipeline validation, and converting between YAML and CUE formats using `cue import` and `cue export` commands. Explore creating reusable triggers and modules to eliminate code duplication across repositories while implementing security best practices by pinning action versions to specific SHAs for safer, compliant builds. Adopt CUE incrementally in your existing workflows, keeping the GitHub Actions features you love while eliminating the pain of managing massive YAML files and treating your configuration as code with proper policy enforcement.
