Developed AWS KMS key decryption support for S3 within the coralogix/terraform-coralogix-aws repository, enabling customer-managed CMK workflows in the Coralogix AWS Shipper module. The work involved introducing a configurable KMS ARN variable and updating IAM policies to grant precise decryption permissions, thereby enhancing security and compliance for S3 data. Documentation, including the changelog, usage examples, and module README, was thoroughly updated to reflect the new functionality and streamline onboarding. The implementation leveraged Terraform and HCL for infrastructure as code, with a focus on AWS services such as KMS, IAM, and S3. No major bugs were addressed.
