terraform import example

import.md

1. Setup a .tf file

# main.tf

provider "aws" {
    region = "us-east-1"
}

resource "aws_s3_bucket" "bucket" {}

2. From command line run:

terraform import aws_s3_bucket.bucket hashi-implementation-svc-tools

3. Run terraform show

# aws_s3_bucket.bucket:
resource "aws_s3_bucket" "bucket" {
    arn                         = "arn:aws:s3:::hashi-implementation-svc-tools"
    bucket                      = "hashi-implementation-svc-tools"
    bucket_domain_name          = "hashi-implementation-svc-tools.s3.amazonaws.com"
 ...

4. Copy and paste the output from terraform show into the .tf file and run terraform plan

terraform plan

5. Modify the terraform code until the plan passes
