terraform-cost-estimation VS checkov

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.

1. Checkov: https://github.com/bridgecrewio/checkov Checkov is a static code analysis tool that helps developers prevent cloud misconfigurations during the development phase by scanning Terraform, CloudFormation, Kubernetes, and more.

Checkov Owner/Maintainer: Prisma Cloud by Palo Alto Networks (acquired in 2021) Age: First released on GitHub on March 31st, 2021 License: Apache License 2.0

‍Checkov is another great tool that examines your Terraform files (.tf), parsing the configurations and evaluating them against a comprehensive set of predefined policies. It scans Terraform-managed infrastructure and detects misconfigurations that could lead to security issues or non-compliance with best practices and regulations.

Bridgecrew — Infrastructure as code (IaC) security powered by the open source tool - Checkov. The core Bridgecrew platform is free for up to 50 IaC resources.

Kustomize: It provides a solution to customize the Kubernetes resource base configuration and differential configuration without template and DSL. It does not solve the constraint problem itself, but needs to cooperate with a large number of additional tools to check constraints, such as Kube-linter, Checkov and kubescape.

Checkov is a versatile static code analysis tool designed for infrastructure as code (IaC) and software composition analysis (SCA). It supports a wide range of technologies, including Terraform, CloudFormation, Kubernetes, Docker, and others, to detect security and compliance issues through graph-based scanning. Checkov also performs SCA scans, identifying vulnerabilities in open source packages and images by checking for Common Vulnerabilities and Exposures (CVEs). Additionally, it is integrated into Prisma Cloud Application Security, a platform that helps developers secure cloud resources and infrastructure-as-code files, enabling the identification, rectification, and prevention of misconfigurations throughout the development lifecycle.

For your Dockerfiles, you can also scan them. There are lots of tools that can check your Dockerfiles. They will validate if Dockerfile is compliant with Docker best practices such as not using root user, making sure a health check exists, and not exposing the SSH port. You can use Snyk and Checkov.

We use https://www.checkov.io/ for this, it's very simple to get started with and works really well as PR quality gate

Once there is a CI pipeline for delivering infra changes you can add static code analysis tools (checkov) and even start testing changes (terratest)
