Are you struggling to integrate manually created resources into your Terraform-Terragrunt management system? While importing resources into Terraform is a well-documented process, it becomes quite tricky when incorporating pre-existing resources under Terragrunt’s umbrella. Fear not! In this comprehensive guide, I'll walk you through the step-by-step process of seamlessly integrating your manually provisioned infrastructure into Terraform-Terragrunt’s fold.

Steps to Integrate Manual Resources:

Begin by listing all resources currently managed by Terraform-Terragrunt:

# Step 1: Assess Your Managed Resources
terragrunt state list

• Similar to importing resources in Terraform, add the following snippet to any file to initiate the import process. Replace placeholders with your resource specifics:

import {
 to = resourcetype.resourcename
 id = "your resource id"
}

• Next, generate a code snippet to facilitate efficient management of the imported resource:

terragrunt plan -generate-config-out=yourdesiredfilename.tf

• Note that the generated configuration file won’t be found in the usual tf-files section. Navigate to the Terragrunt cache files to locate it:

.terragrunt-cache/files-located-here

• Copy the generated configuration file from the cache and paste it into the original tf-files location.
• Apply the changes to ensure that your infrastructure aligns with the Terraform-Terragrunt code:

terragrunt apply

• Confirm that your manually provisioned infrastructure now seamlessly matches the Terraform-Terragrunt code:

• By following these steps, you can efficiently integrate manual resources into Terraform-Terragrunt management, streamlining your infrastructure control process.
