Collie CLI

Collie is a tool for building and managing landing zones for AWS, Azure or GCP as terraform modules.

Use collie to

  • define your core cloud architecture and landing zone(s) using maintainable terraform modules
  • discover and leverage ready-to-use modules implementing best-practice solutions to common landing zone challenges from Collie Hub
  • leverage an efficient, opinionated terraform workflow that eliminates boilerplate and produces great documentation for application and security teams

๐Ÿฅœ Collie in a nutshell

Collie is a tool to streamline building and managing landing zones using terraform for AWS, Azure and GCP. Think of collie like a wrapper around terraform to scaffold, develop and deploy terraform modules.

  • platform engineers use collie to manage a structured git repository containing all code defining their landing zone(s)
  • collie leverages a terraform workflow (powered by terragrunt) to break down complex landing zones into modular, logically structured kit modules
  • kit modules are standard terraform modules following minimal conventions
  • collie lets you import community-maintained modules from Collie Hub and customize them in a fork & own approach

  • terraform to define landing zones using infrastructure as code
  • terragrunt to build and deploy terraform
