terraform-aws-config-state

This terraform code creates state backend using AWS S3 bucket and DynamoDB table (described here). It is very handy when working with multiple environments/workspaces in a team.

Usage

Configuration

Set the following variables if you want to customize it:

  • region - region where to deploy resources (us-east-1 by default)
  • bucket_name - s3 bucket name (tfstate by default)
  • bucket_versioning - controls s3 bucket versioning (false by default)
  • dynamodb_table_name - dynamodb table name (tfstate by default)

Also prepare your AWS configuration (proper credentials) or adjust provider config section.

Applying

Apply code to create resources

terraform apply

In outputs there is terraform_config with generated terraform configuration you can use in your work with multiple environments using workspaces (with locking!)

You can paste it directly into new terraform code where you want to start using multiple workspaces:

terraform output terraform_config > tfstate.tf

Then follow documentation on how to use workspaces and leverage it when dealing with multiple environments and many people working with code.

S3 bucket name caveat

Because of the fact that all AWS S3 bucket names are global, a random suffix is created during deployment and appended to provided bucket name to avoid naming conflicts.
