1. Prerequisites<\/h2>\n\n\n\n

Open Windows PowerShell or Windows Terminal.<\/p>\n\n\n\n

Check your Windows package manager and development tools:<\/p>\n\n\n\n

winget --version\ngit --version\npy --version\nterraform version<\/code><\/pre>\n\n\n\n
If Git and Python are missing, install them:<\/p>\n\n\n\n
winget install -e --id Git.Git\nwinget install -e --id Python.Python.3.13<\/code><\/pre>\n\n\n\n
Restart PowerShell after installing software so the updated PATH is loaded.<\/p>\n\n\n\n
2. TFLint<\/h2>\n\n\n\n
TFLint checks Terraform code for potential errors, deprecated syntax, unused declarations, and provider-specific issues.<\/p>\n\n\n\n
Install (WinGet):<\/p>\n\n\n\n
winget install -e --id TerraformLinters.tflint<\/code><\/pre>\n\n\n\n
Verify:<\/p>\n\n\n\n
tflint --version\nGet-Command tflint<\/code><\/pre>\n\n\n\n
First execution in your Terraform project:<\/p>\n\n\n\n
cd C:\\terraform-project\n\n# Initialize configured TFLint plugins\ntflint --init\n\n# Scan Terraform files in the current directory\ntflint\n\n# Scan Terraform directories recursively\ntflint --recursive\n\n# Show available options\ntflint --help<\/code><\/pre>\n\n\n\n
--init<\/code> installs any configured external ruleset plugins; the built-in Terraform ruleset is already included.<\/p>\n\n\n\n
Official source: TFLint installation and usage<\/a>.<\/p>\n\n\n\n
3. Terraform Docs<\/h2>\n\n\n\n
terraform-docs<\/code> automatically generates documentation for Terraform providers, resources, variables, outputs, and modules.<\/p>\n\n\n\n
Install using Scoop:<\/p>\n\n\n\n
If Scoop is not installed, run the following in a regular (non-administrator) PowerShell session:<\/p>\n\n\n\n
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser\nInvoke-RestMethod -Uri https:\/\/get.scoop.sh | Invoke-Expression<\/code><\/pre>\n\n\n\n
Now install terraform-docs:<\/p>\n\n\n\n
scoop bucket add terraform-docs https:\/\/github.com\/terraform-docs\/scoop-bucket\nscoop install terraform-docs<\/code><\/pre>\n\n\n\n
Verify:<\/p>\n\n\n\n
terraform-docs --version\nGet-Command terraform-docs<\/code><\/pre>\n\n\n\n
First execution:<\/p>\n\n\n\n
cd C:\\terraform-project\n\n# Generate Markdown documentation in the terminal\nterraform-docs markdown table .\n\n# Generate README.md automatically\nterraform-docs markdown table --output-file README.md --output-mode inject .\n\n# View the generated documentation\nGet-Content README.md\n\n# Help\nterraform-docs --help<\/code><\/pre>\n\n\n\n
The inject<\/code> option updates the generated documentation section without replacing the rest of an existing README.<\/p>\n\n\n\n
Official source: Terraform Docs installation<\/a>.<\/p>\n\n\n\n
4. Trivy<\/h2>\n\n\n\n
Trivy scans Terraform configurations for security misconfigurations and can also scan container images, dependencies, and secrets.<\/p>\n\n\n\n
Install (WinGet):<\/p>\n\n\n\n
winget install -e --id AquaSecurity.Trivy<\/code><\/pre>\n\n\n\n
Verify:<\/p>\n\n\n\n
trivy --version\nGet-Command trivy<\/code><\/pre>\n\n\n\n
First execution:<\/p>\n\n\n\n
cd C:\\terraform-project\n\n# Scan Terraform code for security misconfigurations\ntrivy config .\n\n# Show only high and critical findings\ntrivy config --severity HIGH,CRITICAL .\n\n# Scan vulnerabilities, secrets, and misconfigurations\ntrivy fs --scanners vuln,misconfig,secret .\n\n# Scan a container image\ntrivy image alpine:3.21\n\n# Show command help\ntrivy --help<\/code><\/pre>\n\n\n\n
The first scan may download Trivy’s security databases and checks, so internet connectivity is required.<\/p>\n\n\n\n
Official source: Trivy installation<\/a> and Terraform scanning<\/a>.<\/p>\n\n\n\n
5. tenv<\/h2>\n\n\n\n
tenv<\/code> is a version manager for Terraform, OpenTofu, Terragrunt, and related tools. It is useful when different projects require different Terraform versions.<\/p>\n\n\n\n
Install (WinGet):<\/p>\n\n\n\n
winget install -e --id Tofuutils.Tenv<\/code><\/pre>\n\n\n\n
Verify:<\/p>\n\n\n\n
tenv version\nGet-Command tenv<\/code><\/pre>\n\n\n\n
First execution:<\/p>\n\n\n\n
# Install the latest stable Terraform version\ntenv tf install latest\n\n# Select the latest installed Terraform version\ntenv tf use latest\n\n# Verify Terraform\nterraform version\n\n# List locally installed Terraform versions\ntenv tf list\n\n# Detect the version selected for the current directory\ntenv tf detect\n\n# List available remote Terraform versions\ntenv tf list-remote<\/code><\/pre>\n\n\n\n
Optional: Install OpenTofu<\/p>\n\n\n\n
tenv tofu install latest\ntenv tofu use latest\ntofu version<\/code><\/pre>\n\n\n\n
If Terraform was previously installed separately, check which executable PowerShell is using:<\/p>\n\n\n\n
Get-Command terraform -All<\/code><\/pre>\n\n\n\n
The tenv-managed executable should take precedence in PATH for tenv version switching to work correctly.<\/p>\n\n\n\n
Official source: tenv documentation<\/a>.<\/p>\n\n\n\n
6. pre-commit<\/h2>\n\n\n\n
pre-commit<\/code> runs automated checks before Git commits to help catch problems early.<\/p>\n\n\n\n
Install using Python and pipx:<\/p>\n\n\n\n
# Install pipx\npy -m pip install --user pipx\n\n# Add pipx executables to PATH\npy -m pipx ensurepath<\/code><\/pre>\n\n\n\n
Restart PowerShell, then run:<\/p>\n\n\n\n
pipx install pre-commit<\/code><\/pre>\n\n\n\n
Verify:<\/p>\n\n\n\n
pre-commit --version\nGet-Command pre-commit<\/code><\/pre>\n\n\n\n
First execution inside a Git repository:<\/p>\n\n\n\n
cd C:\\terraform-project\n\n# Initialize Git only if this is not already a repository\ngit init\n\n# Generate a sample hook configuration\npre-commit sample-config | Out-File -Encoding utf8 .pre-commit-config.yaml\n\n# Install Git hooks\npre-commit install\n\n# Stage files for the initial test\ngit add .\n\n# Run hooks against all tracked files\npre-commit run --all-files\n\n# View available commands\npre-commit --help<\/code><\/pre>\n\n\n\n
Once installed, configured checks run automatically when you execute git commit<\/code>.<\/p>\n\n\n\n
Official source: pre-commit documentation<\/a> and pipx installation<\/a>.<\/p>\n\n\n\n
7. Verify all five installations together<\/h2>\n\n\n\n
After completing the installations and reopening PowerShell, run:<\/p>\n\n\n\n
Write-Host \"=== TFLint ===\"\ntflint --version\n\nWrite-Host \"=== Terraform Docs ===\"\nterraform-docs --version\n\nWrite-Host \"=== Trivy ===\"\ntrivy --version\n\nWrite-Host \"=== tenv ===\"\ntenv version\n\nWrite-Host \"=== pre-commit ===\"\npre-commit --version\n\nWrite-Host \"=== Terraform ===\"\nterraform version<\/code><\/pre>\n\n\n\n
8. Quick hands-on Terraform lab<\/h2>\n\n\n\n
If you don’t have an existing Terraform project, create a sample project first.<\/p>\n\n\n\n
# Create a demo directory\nNew-Item -ItemType Directory -Force \"$HOME\\terraform-tools-demo\" | Out-Null\nSet-Location \"$HOME\\terraform-tools-demo\"\n\n# Create example Terraform code\n@'\nterraform {\n  required_version = \">= 1.5.0\"\n}\n\nvariable \"project_name\" {\n  description = \"Name of the demo project\"\n  type        = string\n  default     = \"terraform-demo\"\n}\n\noutput \"project_name\" {\n  description = \"Selected project name\"\n  value       = var.project_name\n}\n'@ | Set-Content -Encoding utf8 main.tf\n\n# Run checks\nterraform fmt\nterraform validate\ntflint --init\ntflint\nterraform-docs markdown table .\ntrivy config .<\/code><\/pre>\n\n\n\n
These commands allow you to test Terraform formatting, validation, linting, documentation generation, and security scanning on Windows without creating cloud infrastructure.<\/p>\n\n\n\n
9. Quick command reference<\/h2>\n\n\n\n

The installation commands were checked against current documentation and package listings. They have not been executed on your Windows computer. The terraform-docs Scoop command assumes its bucket was added in Section 3.<\/p>\n","protected":false},"excerpt":{"rendered":"
