ArgoCD and Metrics Server version update.

Change Summary

This update primarily focuses on upgrading two critical components within our infrastructure-as-code (IaC) setup: Argo CD and Metrics Server. The changes involve updating the Helm chart versions for both services to incorporate the latest features, bug fixes, and security patches.

Technical Details

• Argo CD Update:
  • File: IaC/modules/argocd/main.tf
  • Change: Updated the Argo CD Helm chart version from 9.2.2 to 9.2.3.
  • Implementation: Modified the version attribute within the helm_release resource for Argo CD.
• Metrics Server Update:
  • File: IaC/modules/metrics/main.tf
  • Change: Updated the Metrics Server Helm chart version from 3.12.2 to 3.13.0.
  • Implementation: Modified the version attribute within the helm_release resource for Metrics Server.

Key Learnings & Insights

• Reasoning Behind Changes:
  • Keeping our infrastructure components up-to-date is crucial for security, performance, and feature enhancements. The updates to Argo CD and Metrics Server ensure that we benefit from the latest improvements and fixes.
• Problem-Solving Approach:
  • A systematic approach was used to identify the components requiring updates. This involved reviewing release notes and changelogs for both Argo CD and Metrics Server.
• Best Practices:
  • Regularly scheduled reviews and updates of Helm chart versions help maintain a secure and efficient infrastructure.
  • Versioning should be managed carefully to avoid breaking changes, ensuring a smooth deployment process.

Impact Assessment

• Overall System Impact:
  • These updates are expected to enhance the stability and security of our CI/CD pipeline (Argo CD) and monitoring capabilities (Metrics Server).
• Performance & Security:
  • The new versions may include performance optimizations and security patches, contributing to a more robust system.
• Breaking Changes:
  • No breaking changes are anticipated from these minor version updates. However, it is always good practice to test in a staging environment before rolling out to production.

Developer Notes

• Gotchas & Edge Cases:
  • Ensure that all dependencies and configurations are compatible with the new Helm chart versions.
  • Monitor the deployment closely for any unforeseen issues, particularly with custom configurations or values.
• Future Improvements:
  • Consider implementing automated version checks and updates for Helm charts to streamline the update process.
  • Explore the possibility of canary releases for critical infrastructure components to minimize risk.
