Terraform and RIALTO

In order to set up our AWS infrastructure (networking, servers, access settings etc.) we use Terraform, a tool for cross platform Infrastructure as Code.

Terraform-related repositories

• terraform-aws - our main DLSS code repository (this should be your starting point)
• terraform-module-aws-ecs - ECS definitions
• terraform-module-aws-network - [VPC] (https://aws.amazon.com/vpc/)
• terraform-module-aws-route53 - DNS

Terraform Workflow

After installing the Terraflow binary on your localhost, clone the terraform-aws repository and you're ready to start working. When experimenting or building out new features, use the development organization. The basic layout of the workflow is:

1. Make changes in the development organization.
2. Run terraform init if you have not already done so.
3. Run terraform plan.
4. If terraform plan succeeded, and its output looks sane, make AWS changes with terraform apply.

Unfortunately, many runtime errors do not appear until you run terraform plan.
