Importing AWS resources to terraform.txt

Importing AWS resources to terraform.txt

1. Install Terraform on mac
 
brew install hashicorp/tap/terraform
 
brew install terraform
 
 
2. Install the awscli

brew install awscli

3. Configure the credentials 

aws configure

It will create 2 files 

/Users/kiran_chavala/.aws/config
/Users/kiran_chavala/.aws/credentials


4. Install terraformer tool
 
To import the existing resources from (AWS, Google cloud,AZURE) 
 
https://github.com/GoogleCloudPlatform/terraformer
 
 
brew install terraformer

5. Create a provider.tf file with the following content

mkdir -p test

cd test
 
vi provider.tf


provider "aws" {
region = "ap-south-1"
}


terraform init


6. To import all the existing resources from your AWS account

terraformer import aws --resources="*" --connect=true --regions=ap-south-1

terraformer import aws --resources=aws_instance --connect=true --regions=ap-south-1


7. This will generate Terraform files for the existing resources (instance)
.
├── generated
│   └── aws
│       └── ec2_instance
│           ├── instance.tf
│           ├── outputs.tf
│           ├── provider.tf
│           └── terraform.tfstate
└── main.tf



8. Now we can control the exisitng resources


cd generated/aws/ec2_instance/

terraform state replace-provider -auto-approve "registry.terraform.io/-/aws" "hashicorp/aws"


terraform init
 
terraform refresh


 
To change the setting of a resource after editing the respective resource tf file
 
terraform plan
 
terraform apply
