Tanel Saar enhanced the entigolabs/entigo-infralib repository by improving AWS EKS infrastructure automation using Terraform and HCL. He focused on reducing configuration drift in the EKS addon, removing unsupported configuration values to minimize misconfiguration risks and streamline module usage. Tanel also introduced a conditional enable_efs_csi variable, allowing users to opt in to EFS CSI driver and IAM role deployment, which increased flexibility for storage backends in EKS clusters. His work improved module maintainability and deployment clarity, with all changes clearly documented for traceability. The updates addressed both feature expansion and bug resolution within a concise, well-scoped engineering effort.
