tf-cf-aws-3tier-dev (WIP NOT COMPLETE)
In this project we attempt to automate infrastructure provisioning in Amazon Web Services. The infrastructure includes the services essential for a customer managed three-tier-app. An attempt is made to convert as many services or resources into Terraform plans as possible. The project is intended as a MVP and to be tested in a non-production AWS account.
The author(s) assumes the reader has access to Amazon Web Services with sufficient IAM permissions. Access to provisioned GNU+Linux compute requires a personal SSH key. Access to Windows Server compute requires a local or domain account.
Experience handling infrastructure as code and Terraform is very helpful as well. Consider reading Terraform Up and Running for the fundamentals.
Terraform >= 1.4.XYZ
hashicorp/aws >= v5.3.0
- Install requirements
- Configure AWS Account Credentials
- Clone repository
- Generate a
.tfvarsfile using the template
- Confirm SSH and RDP access is available
- Apply desired application tests
DO NOT STORE SSH KEYS, API KEYS, OR TERRAFORM STATE FILES REMOTELY. PLEASE KEEP THEM SECURE ON YOUR LOCAL MACHINE
Testing and Debugging
Terraform provides simple linting and validation functionality. Keep in mind validation or linting does not guarantee a successful deployment.
Quickly check your plans:
terraform fmt && terraform validate
The current IaC implementation will fail to provision. There improvements in use of the
for_each meta-argument to be made. Lastly, the implementation is not resilient to failures and requires an overhaul. Future plans will consider serverless and auto-scaling cloud services to bolster resiliency.
