Its README positions it as a security and governance tool to run after terraform init and before commands such as validate, plan, or apply. ### Project history The project was built around a simple policy model: read `terraform version -json`, compare provider names and optional version constraints against a YAML allow list, and fail when a disallowed provider appears. The README contrasts this with `.terraform.lock.hcl` and `required_providers`, arguing that those mechanisms do not provide the same centralized provider allow-list control. ### Adoption history Adoption appears concentrated in CI and platform-engineering contexts. Homebrew packages tfprovidercheck as a bottled formula, while the README emphasizes GitHub Actions usage and environment-variable configuration for workflows where pull requests should not be able to tamper with the policy. ### How it is used Typical usage pipes `terraform version -json` into `tfprovidercheck`, optionally passing `-config`. Configuration can come from a command-line path, `TFPROVIDERCHECK_CONFIG_BODY`, `TFPROVIDERCHECK_CONFIG`, or `.tfprovidercheck.yaml` in the current directory. ### Why package nerds care For package-focused infrastructure users, tfprovidercheck is notable because it treats Terraform providers as executable dependencies that need admission control. It packages that check as a small CLI suitable for CI images, Homebrew installs, and repository policy workflows. ### Timeline - 2025: GitHub tags list v1.0.6 in July and v1.0.7 in December. - 2026: Homebrew formula metadata lists stable version 1.0.7 with bottled builds. ### Related projects - Terraform CLI - .terraform.lock.hcl - Terraform required_providers - GitHub Actions ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
