Terraform

Scripts

The structure and instructions provided in TEMPLATE should be followed as best as possible when creating root terraform module directories.

Backend Convention

The root terraform modules should use an S3 backend, with a DynamoDB lock file.

backend "s3" {
  region         = "eu-central-1"
  bucket         = "tf-state-aws-migration-test"
  key            = "<root_module>.tfstate"
  dynamodb_table = "tf-state-lock-capci-group4-<root_module>"
  encrypt        = "true"
}

Replace <root_module> with the corresponding root module name.
E.g., key = "aws-migration-lab-rehost-source-vpc.tfstate" for the source VPC root module.
