This repository is part of the presentation "Automating Cloud Cost Management with Terraform" presented at the Cloud Conference Day 2023. For more information about the presentation, please visit here.

This code serves as a practical example of how to integrate Infracost with your GitHub Action workflow to receive cost estimates directly in Pull Requests.

1. Configuration of Secrets

The first step for integration is to create the necessary secrets in your project's repository if you don't mind. Be sure to add the following secrets:

• ARM_CLIENT_ID: ID for the service principal created in Microsoft Azure.
• ARM_CLIENT_SECRET: Secret for the service principal created in Microsoft Azure.
• ARM_SUBSCRIPTION_ID: ID of the subscription where you plan to deploy resources.
• ARM_TENANT_ID: Tenant ID where you plan to deploy resources.
• INFRACOST_API_KEY: Infracost API key for integration.

2. Using the Cost Management Workflow

After configuring the secrets, follow the steps below to use the cost management workflow:

• Create a new branch in your repository and make the necessary code changes.
• Create a Pull Request on GitHub with your changes.
• After creating the Pull Request, the PLAN workflow will be automatically triggered.
• You can view the Infracost cost estimate in the comments of the Pull Request.

3. To destroy resources

To destroy the resources deployed by the workflow, you need to trigger the destroy action (destroy.yml) manually.

Make sure to review the cost estimates to ensure that your changes will not adversely affect the project's budget.

Take advantage of the Infracost integration to make informed decisions about the costs associated with changes in cloud infrastructure!
