Question 1

How to install terraform-cleaner on Windows?

Accepted Answer

Download the Windows binary from the releases page on GitHub, then place it in your PATH or run it directly from the command line. It's a standalone executable with no dependencies.

Question 2

terraform-cleaner vs TFLint for unused variables: which should I use?

Accepted Answer

Terraform-cleaner is specialized and lighter for unused variable detection only, while TFLint offers broader checks including unused variables. Choose terraform-cleaner if you need a focused tool, or TFLint for comprehensive linting.

Question 3

Does terraform-cleaner work with nested Terraform modules?

Accepted Answer

The README doesn't specify, but it likely scans the provided directory path. You may need to run it on each module separately or check if it supports recursive scanning, as it's designed for single modules.

Question 4

Can I integrate terraform-cleaner into my CI/CD pipeline?

Accepted Answer

Yes, since it's a CLI tool, you can add it to CI/CD scripts by downloading the binary and running it as a step. However, the README lacks specific examples, so you'll need to script the integration yourself.

Question 5

What Terraform versions is terraform-cleaner compatible with?

Accepted Answer

The README doesn't state version compatibility, but it parses Terraform files, so it should work with recent versions like 0.12+. Always test with your specific setup to ensure accuracy.

Question 6

How does terraform-cleaner handle false positives in dynamic code?

Accepted Answer

It performs static analysis, so it might flag variables as unused in cases with dynamic blocks or conditional logic. You'll need to manually verify results, as the tool doesn't account for runtime behavior.
