terraform-cost-estimation VS tflint

terraform-cost-estimation – Free cost estimation service for your plans. Check out also this list that includes a lot more awesome terraform tools.

Could be relatively simple, just filter out everything that you don't need. Possibly as a separate cli tool for transparency. For example, Terraform Cost Estimation by Anton Babenko uses a jq script to do this.

Let me plug-in a couple more 100% free solutions for cost estimation I have been creating in the open-source: 1. terraform-cost-estimation.com - web-service which accepts terraform plan or terraform state. 2. https://github.com/antonbabenko/terraform-cost-estimation - Anonymized, secure, and free Terraform Cost Estimation tool using cost.modules.tf service. There are instructions on how to integrate this in CI/CD pipeline or with OPA, as well as explaining what does make it really anonymized. 3. Weekly Youtube videos of me developing/hacking Terraform AWS pricing module - part1, part2, part3.

‍TFLint is a Terraform linter focused on possible errors, best practices, and style conventions in your Terraform code.

TFlint is a powerful linter for Terraform, designed to catch errors and issues that terraform plan may not detect. As Terraform grows in popularity for infrastructure as code, the need for robust tools to ensure code quality and reliability becomes paramount. TFlint fulfills this need by analyzing Terraform configurations to find problems that are not covered by syntax checks. It checks for things like unsuitable AWS instance types, incorrect IAM policy syntax, and the use of deprecated syntax or features. By integrating TFlint into the development process, users can proactively identify potential problems, improving the stability and efficiency of their infrastructure deployments. This additional layer of validation is crucial for maintaining high standards in complex, cloud-based infrastructures.

Looking at the description, https://github.com/terraform-linters/tflint , I think it's not what I am looking for. The reason I used a different tcp port is to make the health check on load balancer fail. It's also the same as not changing the tcp port but developer making a code change in their javascript, nodejs, java, etc fail to start properly. If that happens, load balancer's health check will fail as well.

TFLint is an open-source infrastructure as code linter tool that helps developers and DevOps teams identify potential issues and errors in their Terraform code by checking the Terraform configuration files for best practices, coding standards, and policy compliance.

Indeed, that is the case, atm. Your comment got me searching a little bit more. It seems that they are planning to implement a flag for small fixes https://github.com/terraform-linters/tflint/issues/266

Sounds like tflint to me!

I created a .tflint.hcl with the following content: https://github.com/terraform-linters/tflint/blob/master/docs/user-guide/config.md (The example)

TFLint: This is a Terraform linter that checks for errors and best practices in your Terraform code. TFLint helps to catch common mistakes, such as variable name clashes, missing required variables, or invalid resource arguments. It also checks for compliance with best practices, such as naming conventions and resource ordering. By using TFLint, you can catch errors early on, which helps to improve the quality of your Terraform code.

tflint: Linter para Terraform, serve para avisar sobre problemas com sintaxe, erros nos principais provedores de nuvem, garantir boas práticas e outras coisas.
