Installing Terraform

Hashicorp Learn Install Tutorial

• InstallUpgradeTerraform.ps1 is a small PS script I wrote to upgrade/install the Terraform binary

• Terraform can now be installed and maintained with winget

  KV C:\Users\karl.vietmeier\repos> winget list terraform

Terraform Notes

Terraform commands:
A good cheat sheet I ran across
https://acloudguru.com/blog/engineering/the-ultimate-terraform-cheatsheet

Apply/destroy without prompting

terraform destroy --auto-approve
terraform apply --auto-approve

Run and over-ride locks

terraform destroy -lock=false --auto-approve
terraform apply -lock=false --auto-approve

Run with a .tfvars file

terraform apply -var-file=".\MultiLinuxVM-vars.tfvars"
terraform destroy -var-file=".\MultiLinuxVM-vars.tfvars"

Put it all together

terraform apply --auto-approve -var-file=".\<fname>.tfvars"
terraform destroy --auto-approve -var-file=".\<fname>.tfvars"

---

PowerShell Alias/Shortcuts So you don't have to keep calling out the non-standard tfvars file.

function tfapply {
  # Run an apply using the tfvars file in the current folder
  $VarFile=(Get-ChildItem -Path .  -Recurse -Filter "*.tfvars")
  terraform apply --auto-approve -var-file="$VarFile"
}

function tfdestroy {
  # Run a destroy using the tfvars file in the current folder 
  $VarFile=(Get-ChildItem -Path .  -Recurse -Filter "*.tfvars")
  terraform destroy --auto-approve -var-file="$VarFile"
}

function tfshow {
  # 
  terraform show
}
