# Lint Terraform modules for provider mistakes and policy violations with TFLint

Check Terraform before plan or apply so invalid attributes, provider-specific mistakes, and custom rule violations are caught early.

## Prerequisites

TFLint binary, Terraform configuration, optional plugin rules

## Installation

Use the upstream install or setup path that matches your environment:
- brew install terraform-linters/tap/tflint
- docker run --rm -v $(pwd):/data -t ghcr.io/terraform-linters/tflint
- docker run --rm -v $(pwd):/data -t --entrypoint /bin/sh ghcr.io/terraform-linters/tflint -c "tflint --init && tflint"

Requirements and caveats from upstream:
- ### Docker
- Instead of installing directly, you can use the Docker image:
- To download plugins, you can override the entrypoint to a shell (sh) to run --init and the main command in a single docker run command:

Basic usage or getting-started notes:
- Download the appropriate archive from the [latest release](https://github.com/terraform-linters/tflint/releases/latest), verify it, and install the binary:
- console
- curl -sSLO https://github.com/terraform-linters/tflint/releases/latest/download/tflint_linux_amd64.zip
