Code Quality

Before plan and apply, always clean up your code:

use terraform fmt to rewrite Terraform configuration files to a canonical format and style.
use terraform validate to validate the configuration syntax and internal consistency
use pre-commit to run more checks
- community member @antonbabenko/ built and maintains pre-commit-terraform

Importing resources

use the terraform import command:

Create a resource in your Terraform code:

resource "aws_s3_bucket" "hug_demo" {
  bucket = "hug-demo"
}

Then run the terraform import command:

terraform import \
    aws_s3_bucket.hug_demo "hug-demo"

specify the Terraform-native resource (aws_s3_bucket.hug_demo) as well as the provider resource (hug-demo)

use Terraformer for importing large sets of resources
