Terraform Integration

The terraform command detects TF_VAR_* environment variables used in your Terraform configurations and verifies they exist in your .env files.

Usage

envcheck terraform . --env .env
envcheck terraform infra/ --env .env.prod

How it works

Terraform allows setting variables via environment variables with the TF_VAR_ prefix:

# variables.tf
variable "database_url" {
  type = string
}

# .env
TF_VAR_database_url=postgres://localhost:5432/db

envcheck scans your .tf files for variable declarations and ensures matching TF_VAR_* entries exist in your .env.

Example Output

$ envcheck terraform infra/ --env .env

Scanning infra/variables.tf
  W007: Variable 'api_key' declared but TF_VAR_api_key missing in .env
  W008: TF_VAR_legacy_token in .env but no matching variable declaration
