[Verse 1] Start with scattered scripts across your desktop maze Each deployment copying code in repetitive ways Resources hardcoded, variables nowhere found Technical debt accumulates, your infrastructure drowns But there's a better method, architects understand Modules are the building blocks for scaling what you've planned [Chorus] Modularize, parametrize, make it reusable Input variables flowing through, outputs beautiful Source and version, source and version, dependencies clear Abstract the complexity, let the patterns appear Module Registry, Module Registry, sharing what you build Terraform modules are the foundation, properly skilled [Verse 2] Define your inputs with descriptions crystal bright Type constraints and validations keep your data tight Locals block for calculations, transforming what comes in Output values expose the resources you create within Nest your modules deep, composition is the key Child modules inherit parent scope naturally [Chorus] Modularize, parametrize, make it reusable Input variables flowing through, outputs beautiful Source and version, source and version, dependencies clear Abstract the complexity, let the patterns appear Module Registry, Module Registry, sharing what you build Terraform modules are the foundation, properly skilled [Bridge] Directory structure matters more than you might think Environments folder with dev, staging, prod in sync Modules folder holds your treasures, tested and refined README documentation helps the next dev find Version tagging for releases, semantic numbering scheme Breaking changes need major bumps, that's the versioning dream [Verse 3] Remote state backends connecting modules cross-team Data sources pull existing resources into your scheme Count and for-each parameters multiply your might Conditional creation with count equals zero or one bright Provider configuration passed down through the chain Module composition eliminates redundant strain [Chorus] Modularize, parametrize, make it reusable Input variables flowing through, outputs beautiful Source and version, source and version, dependencies clear Abstract the complexity, let the patterns appear Module Registry, Module Registry, sharing what you build Terraform modules are the foundation, properly skilled [Outro] From monolith to microservices, infrastructure grows Modules are your secret weapon, that's how expertise shows
