tflint

In the Unix world, a linter is a static code analysis tool to detect minor errors. Initially created for the C programming language, many different lint programs have been developed, including for Terraform. Previously, we showed the terraform validate command, which validates your configuration, including the syntax and verification of reusable modules. This command is excellent for finding common syntax errors such as missing brackets or unclosed quotation marks. tflint (https://github.com/terraform-linters/tflint) serves a similar function but detects possible errors, such as invalid instance types, and provides more information, such as any unused declaration, deprecated syntax, and violation of best practices. Therefore, tflint not only finds errors but also helps keep the code cleaner and easier to manage.

tflint consists of a single executable and extensible plugins. To install tflint on your machine, follow the instructions at https://github.com/terraform-linters...
