tfstate-backend-aws

terraform

This module provides a wrapper around the existing cloudposse/terraform-aws-tfstate-backend.

It allows you to run this module in a pipeline by running make init for example to detect whether the remote state was already created or not. In case the remote state was not created yet the resources are provisioned and the state imported into the new backend.

Usage

You will need a global TF_BUCKET environment variable set. From this variable we source the target bucket name.

To use this project run make init

Verify

To verify it all worked, run aws s3 ls s3://${TF_BUCKET}/tfstate-backend/terraform.tfstate it should display the terraform.tfstate file and date when it was created.

You can overwrite where this module stores its state file by setting TF_STATE_KEY when running make init

IAM

It might be useful to you to generate an IAM policy which grants access to the state backend and dynamodb table. This policy can be attached to users or roles. Additionally this module exposes an output called tfstate_backend_access_policy_json which contains the policy document. The tfstate_backend_access_policy_arn output contains the created IAM policy ARN.
