StackSpot Deploy App solution with TF provider

[eduardohyodozup]

Description

StackSpot Runtime engine currently enable to provision cloud resources using Terraform through Infra Plugins.

However, some customers processes need to perform customizable operations to deploy their applications using other tools than Terraform (CodeDeploy, Crossplane...).

Therefore, StackSpot needs to provide a secure and user friendly feature to enable using those other tools, integrated with the StackSpot Platform as a whole.

We agreed to create Terraform Providers that abstract the interaction with the AWS CLI (pre-defined by StackSpot or customized). These providers would be used through infrastructure plugins in the application repository.
