Lint Terraform modules for provider mistakes and policy violations with TFLint

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, verify it, and install the binary:
