Minecraft Terraform Module Introduction

Change Summary

This commit introduces a new Minecraft server module, utilizing Kubernetes and ArgoCD for deployment and management. It includes the creation of necessary Terraform files, configuration of providers, and setup of the Minecraft server as an ArgoCD application.

Technical Details

• New Files Created:
  • IaC/_envcommon/locks/minecraft.terraform.lock.hcl
  • IaC/_envcommon/minecraft.hcl
  • IaC/modules/minecraft/main.tf
  • IaC/modules/minecraft/variables.tf
  • IaC/modules/minecraft/versions.tf
  • IaC/production/homelab/minecraft/.terraform.lock.hcl
  • IaC/production/homelab/minecraft/terragrunt.hcl
  • IaC/production/homelab/terragrunt.stack.hcl
• Configuration Changes:
  • Removed the kube_provider inclusion from IaC/_envcommon/metrics.hcl.
  • Added new provider configurations in IaC/_envcommon/minecraft.hcl for AWS, Kubernetes, and ArgoCD.
  • Configured the Minecraft server module in IaC/modules/minecraft/main.tf to create a Kubernetes namespace and an ArgoCD application.
  • Defined required provider versions and merged tags in IaC/modules/minecraft/versions.tf.
• ArgoCD Application Configuration:
  • Defined an ArgoCD application for the Minecraft server with specific annotations for image updates.
  • Configured the destination server and namespace.
  • Set the Helm chart repository, chart version, and parameters for the Minecraft server.

Key Learnings & Insights

• Modular Infrastructure as Code (IaC):
  • The changes demonstrate a modular approach to IaC, allowing for better organization and reusability of Terraform configurations.
• Automated Deployment with ArgoCD:
  • Using ArgoCD for deployment ensures that the Minecraft server is always up-to-date with the latest chart version, enhancing maintainability.
• Configuration Management:
  • The use of Terraform variables and locals for tagging resources promotes better resource management and identification.

Impact Assessment

• Performance:
  • The introduction of the Minecraft server module should not significantly impact overall system performance, as it is isolated within its namespace.
• Security:
  • Ensure that the Minecraft server is configured with appropriate security measures, such as network policies and RBAC, to prevent unauthorized access.
• Maintainability:
  • The modular approach and use of ArgoCD enhance maintainability by allowing easy updates and rollbacks of the Minecraft server configuration.

Developer Notes

• Gotchas:
  • Ensure that the Kubernetes cluster has sufficient resources to accommodate the Minecraft server.
  • Verify that the ArgoCD server is properly configured and accessible within the cluster.
• Future Improvements:
  • Consider adding more advanced configurations for the Minecraft server, such as custom resource definitions (CRDs) or operator-based management.
  • Explore the possibility of integrating monitoring and logging solutions specifically for the Minecraft server to enhance observability.
