Update n8n image version annotation.

Change Summary

This git diff reflects a modification to the main.tf file within the n8n module of the Infrastructure as Code (IaC) repository. Specifically, the version specification for the n8nio/n8n Docker image has been updated.

Technical Details

• File Modified: IaC/modules/n8n/main.tf
• Change:
  • The version of the n8nio/n8n Docker image has been updated from 1.102.x to 1.x.
  • This change is located within the argocd_application resource definition for the n8n application.
  • The annotation argocd-image-updater.argoproj.io/image-list now points to n8nio/n8n:1.x instead of n8nio/n8n:1.102.x.

Key Learnings & Insights

• Version Flexibility:
  • By changing the version specification from 1.102.x to 1.x, the configuration now allows for any minor or patch version within the major version 1 to be used. This provides greater flexibility in automatically updating to the latest compatible version.
• Semver Strategy:
  • The update strategy remains as semver, ensuring that the updates adhere to semantic versioning principles. This means that only compatible changes (i.e., bug fixes and features that do not break existing functionality) will be automatically applied.
• Maintenance Ease:
  • This change reduces the need for manual updates to the Docker image version, allowing the system to stay current with minimal intervention.

Impact Assessment

• Performance:
  • There should be no direct performance impact from this change. However, future updates to the n8nio/n8n image may introduce performance improvements or degradations.
• Security:
  • Automatically updating to the latest compatible version can enhance security by incorporating the latest patches and fixes.
• Maintainability:
  • This change improves maintainability by reducing the need for manual version updates.
• Breaking Changes:
  • There are no breaking changes introduced by this modification. However, future updates to the n8nio/n8n image might include breaking changes, which should be handled according to the existing update strategy (semver).

Developer Notes

• Gotchas:
  • Ensure that the application is thoroughly tested after an automatic update to the n8nio/n8n image to catch any potential issues introduced by new versions.
• Edge Cases:
  • Be aware that while semantic versioning aims to prevent breaking changes within a major version, there may be edge cases where a minor or patch version introduces unexpected behavior.
• Future Improvements:
  • Consider implementing canary releases or blue-green deployments to mitigate risks associated with automatic updates. This would allow for gradual rollouts and easier rollbacks if issues arise.
