  • Self-service infrastructure as code
    4 projects | dev.to | 12 Mar 2024
    Our first attempt was to introduce other engineering teams to Terraform - the Platform team was already using it extensively with Terragrunt, and using Atlantis to automate plan and apply operations in a Git flow to ensure infrastructure was consistent. We'd written modules, with documentation, and an engineer would simply need to raise a PR to use the module and provide the right values, and Atlantis (once the PR was approved by Platform) would go ahead and set it up for them.

    Created and maintained by Gruntwork, Terragrunt is a tool designed to enhance Terraform’s capabilities. It acts as a thin wrapper around Terraform, offering additional features to streamline and optimise Terraform usage. Key functions of Terragrunt include helping users keep their Terraform configurations DRY (Don’t Repeat Yourself), efficiently managing multiple Terraform modules, and handling remote state management. By reducing repetition in Terraform code and simplifying the management of complex module dependencies and remote state, Terragrunt makes working with Terraform more efficient, especially for larger or more complex infrastructure deployments.

    I’ve been using Terragrunt [0] for the past three years to manage loosely coupled stacks of Terraform configurations. It allows you to compose separate configurations almost as easily as you compose modules within a configuration. Its got its own learning curve, but its a solid tool to have in the tool box.
