Terraforming in 2021 – new features, testing and compliance

• tf-ecosystem-blog-post

  1 0 3.2 HCL

  Companion repository for blog post about terraform

  

Once again, you can find all the code supporting this this post here.

• tfenv

  22 4,310 5.8 Shell

  Terraform version manager

  

TFEnv - terraform environment switcher inspired (from the ruby world) by rbenv written with shell scripts;

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• terraform-switcher

  9 1,295 2.6 Go

  A command line tool to switch between different versions of terraform (install with homebrew and more)

Terraform Switcher - yet another project essentially doing the same written in go;

• tflint

  30 4,572 8.9 Go

  A Pluggable Terraform Linter

  

TFLint comes to the rescue. Being yet another open source tool written in go, it comes as a binary much like terraform and does not even require terraform to be installed.

• tfsec

  7 2,991 9.4 Go

  Discontinued Security scanner for your Terraform code [Moved to: https://github.com/aquasecurity/tfsec] (by tfsec)

  

Here again more than one tool exists to assist. We will highlight two of the most popular ones here: tfsec and checkov. Both provide a predefined set of checks that they use to inspect your code, allowing to explicitly open exceptions (if you really want to) by annotating your code with comments, and adjust the configuration to ignore some modules, for example.

• checkov

  54 6,492 9.9 Python

  Prevent cloud misconfigurations and find vulnerabilities during build-time in infrastructure as code, container images and open source packages with Checkov by Bridgecrew.

• terratest

  46 7,330 8.7 Go

  Terratest is a Go library that makes it easier to write automated tests for your infrastructure code.

  

Terratest is probably the closest one can get now a days to testing the specific peace of terraform code. It is a Go library, and requires one to write tests in Go. This is obviously a potential limitation as not all teams have knowledge in Go. On the upside, I would argue that the learning curve of learning Go to get the basics - read enough for writing terraform tests - is not steep if you know already at least one programming language.

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• cli

  7 1,318 5.3 Python

  a lightweight, security focused, BDD test framework against terraform. (by terraform-compliance)

  

A direct open source comparable alternative would be using terraform-compliance. It follows BDD directives so that you can specify in an easy human readable way your expectations, using:

• conftest

  9 2,782 8.5 Go

  Write tests against structured configuration data using the Open Policy Agent Rego query language

  

If you like terraform-compliance, Conftest might also be worth having a look. It has its own DSL to write policies, and allows you to test multiple frameworks. We found this blog post from Lennard Eijsackers very informative, and would thus rather recommend you to check it out.

• inspec

  13 2,810 9.4 Ruby

  InSpec: Auditing and Testing Framework

  

Before we dive into own cloud provider compliance checking services, we want to highlight yet another open source tool, namely InSpec. It allows you to write tests in ruby, and was built on top of RSpec. If you know already awsspec, then this should feel very similar, with the advantage that InSpec also supports GCP and Azure.

• awspec

  1 1,165 7.3 Ruby

  RSpec tests for your AWS resources.
