Terraform import block

 Let's imagine we want to import an SNS Topic into our template.

 We should have something like this, change region, to and id of the import.

terraform {

required_version = ">= 1.13.5"

required_providers {

aws = {

source = "hashicorp/aws"

version = ">= 4.16.1"

}

}

}

# Configure the AWS provider

provider "aws" {

region = "us-east-1" # Replace with your desired region

}

import {

to = aws_sns_topic.AleTopic

id = "arn:aws:sns:us-east-1:XXXX:AleTopic"

}

 

Run to generate the config file for that resource

terraform plan -generate-config-out=generated.tf 

A new file will be generated.

# __generated__ by Terraform

# Please review these resources and move them into your main configuration files.

# __generated__ by Terraform

resource "aws_sns_topic" "AleTopic" {

application_failure_feedback_role_arn = null

application_success_feedback_role_arn = null

application_success_feedback_sample_rate = 0

archive_policy = null

content_based_deduplication = false

delivery_policy = null

display_name = "My topic"

fifo_throughput_scope = null

Run terraform plan

 

Then run terraform apply to bring the changes to the state file.
