terraform-tflint-wrappers

Repo for DSBs TFLint wrapper scripts, ref. https://github.com/terraform-linters/tflint

The intention of the scripts in this repo is to provide a compatible and safe way of installing and running TFLint without having to duplicate code in DSBs terraform project repos.

Call wrapper from remote repo

Bash from remote repo

This is how to call the linux wrapper script from bash without having to store a copy locally:

# Without arguments
curl -s https://raw.githubusercontent.com/dsb-norge/terraform-tflint-wrappers/main/tflint_linux.sh |
  bash -s --

# With arguments
curl -s https://raw.githubusercontent.com/dsb-norge/terraform-tflint-wrappers/main/tflint_linux.sh |
  bash -s -- --help

Powershell from remote repo

This is how to call the powershell wrapper script without having to store a copy locally:

# Without arguments
Invoke-Expression ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/dsb-norge/terraform-tflint-wrappers/main/tflint_windows.ps1'))

# With arguments
Invoke-Command `
  -ScriptBlock ([scriptblock]::Create(((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/dsb-norge/terraform-tflint-wrappers/main/tflint_windows.ps1')) -join "`n")) `
  -ArgumentList $false,$true,$false # Force = false, Remove = true, ExitWithCode = false

Development

Bash

To simulate calling the script from a remote repo during development use:

# Without arguments
bash -s -- < tflint_linux.sh

# With arguments
bash -s -- --uninstall < tflint_linux.sh

Powershell

To simulate calling the script from a remote repo during development use:

# Without arguments
Invoke-Expression ([String]::Join("`n",(Get-Content '.\tflint_windows.ps1')))

# With arguments
Invoke-Command `
  -ScriptBlock ([scriptblock]::Create((Get-Content '.\tflint_windows.ps1') -join "`n")) `
  -ArgumentList $true,$false,$false # Force = true, Remove = true, ExitWithCode = false
