Updated workflows for deploying infrastructure.

Change Summary

This update refines the GitHub Actions workflows for deploying and planning Infrastructure as Code (IaC) changes. Specifically, it modifies the deploy.yml and plan.yml workflows to trigger only when changes are made to the IaC/ directory or the workflow files themselves. Additionally, it streamlines the steps within these workflows to directly apply or plan Terragrunt configurations without separately installing Terragrunt and OpenTofu.

Technical Details

• deploy.yml:
  • Added path filters to trigger the workflow only on changes to IaC/** and .github/workflows/deploy.yml.
  • Renamed the step from Install Terragrunt and OpenTofu to Terragrunt Apply and directly executed the terragrunt apply command.
• plan.yml:
  • Added path filters to trigger the workflow only on changes to IaC/** and .github/workflows/plan.yml.
  • Renamed the step from Install Terragrunt and OpenTofu to Terragrunt Plan and directly executed the terragrunt plan command.

Key Learnings & Insights

• Path Filters: By adding path filters, the workflows are optimized to run only when relevant files are changed, reducing unnecessary executions and saving resources.
• Streamlined Steps: Directly executing terragrunt apply and terragrunt plan simplifies the workflows and reduces potential points of failure by eliminating the separate installation step.
• Efficiency: These changes demonstrate a best practice of minimizing workflow runtime by triggering them only when necessary and streamlining their steps.

Impact Assessment

• Performance: The workflows will now run more efficiently, only when changes are made to the IaC directory or the workflow files themselves.
• Maintainability: Simplifying the steps within the workflows makes them easier to understand and maintain.
• Resource Usage: By reducing the number of times the workflows run, there is a positive impact on resource usage and cost, especially in CI/CD environments.

Developer Notes

• Path Filters: Ensure that any future changes to the IaC directory or workflow files are correctly handled by these path filters.
• Terragrunt Commands: Verify that the Terragrunt configuration is correctly set up to handle the apply and plan commands without additional setup steps.
• Future Improvements: Consider adding additional checks or steps to the workflows for enhanced security or validation before applying changes.
