Terraform AWS Backend S3

Terraform module that creates an S3 bucket and DynamoDB table for backend state files.

Quickstart

This is one of the few modules that you can just run "as is" and then throw away the config and state.

git clone https://github.com/byu-oit/terraform-aws-backend-s3.git
cd terraform-aws-backend-s3/examples/simple
aws sso login
export AWS_PROFILE=my-account-profile
terraform init
terraform apply
cd ../../../
rm -rf terraform-aws-backend-s3

Usage

module "backend-s3" {
  source = "github.com/byu-oit/terraform-aws-backend-s3?ref=v2.0.0"
}

Run terraform apply to create the S3 bucket and DynamoDB table for storing state files. Then add:

terraform {
  backend "s3" {
    bucket          = "terraform-state-storage-<account_number>"
    dynamodb_table  = "terraform-state-lock-<account_number>"
    key             = "my-cool-app.tfstate"
    region          = "us-west-2"
  }
}

to configure your terraform backend to the newly created S3 bucket and DynamoDB table.

Input

Variable	Default	Description
bucket_name	terraform-state-storage-<account_number>	S3 bucket name for state file storage
dynamodb_table_name	terraform-state-lock-<account_number>	DynamoDB table name for state file locking

Output

Name	Description
s3_bucket	S3 bucket object for terraform state storage
s3_bucket_name	Bucket name of the s3_bucket
dynamodb_table	DynamoDB Table object for locking of terraform state

Note about returning objects: Because objects are returned (as opposed to just values), autocomplete may not work. Just add on the key to the end out the output accessor. Even though autocomplete won't work, those values will still be correctly returned.
