Terraform Search Feature Demo

Demo of Terraform v1.14.0's new terraform query command and needed .tfquery.hcl files.

Prerequisites

• Terraform v1.14.0-beta1+
• AWS CLI configured
• SSH public key

Setup Steps

1. Edit variables.tf and add your SSH public key.

2. Initialize and deploy:

   terraform init
   terraform apply

3. Create demo scenario (simulate unmanaged resource):

   # First, comment out the Amazon Linux instance in aws_instance.tf
   # Then remove it from Terraform state
   terraform state rm aws_instance.amazon_linux

4. Search for instances:

   # Find all instances
   terraform query
   
   # Search specific instance
   terraform query -var 'keyword=amazon'

5. Generate configuration:

   terraform query -var 'keyword=4d66' -generate-config-out=found.tf

6. Clean up generated config (experimental feature requires manual fixes):

   • Remove: arn, id, instance_state, availability_zone
   • Fix: amd_sev_snp = "" and conflicting attributes

What It Creates

• 5 managed EC2 instances (Amazon Linux, Ubuntu, Debian, CentOS, Fedora)
• Security group and key pair

Key Files

• aws.tfquery.hcl - Search query definitions
• aws_instance.tf - EC2 instances
