Terraform Parser - Parse Terraform to JSON

terraform-parser

Parse Terraform scripts into JSON

Status

Dec 2022 - This an experimental parser that can parse HCL2

Problem

Terraform scripting can be complex;

An application (or docker image, or lambda) is a black box to infrastructure: Services defined in infrastructure are communicated to the application as a set of environment variables.

We want to define services independently, in terraform, and then merge many services into a single infrastructure specification. Specifically, we want to

• avoiding terraform namespace collision
• merge the vars and other resources
• merge the application environment variables

Solution

Most of the solution is to use terraform modules. The remaining problem is

The hope is to

• parse terraform into Json data
• merge data from different terraform to single spec
• allow Python to modify data easily
• write out terraform (in diff-friendly way)
