October 2024 delivered targeted security and maintainability improvements across two Terraform modules. Key feature implemented: Cloud Object Storage KMS key-scoped authorization policy for terraform-ibm-cos, achieved by parsing the KMS key CRN to extract components and binding the policy to the exact key. The rollout used a create-before-delete approach to avoid service disruption. Major bug fix: cleaned up common-permanent-resources.yaml in terraform-ibm-modules/common-dev-assets by removing obsolete commented-out configurations for activity-tracker and sysdig, reducing confusion and ensuring the file reflects active resource definitions. Overall impact: strengthened security with least-privilege access, improved configuration clarity, and enhanced maintainability across modules, supporting more reliable deployments and easier onboarding. Technologies/skills demonstrated: KMS policy management, CRN parsing for policy scoping, safe deployment and rollback practices, YAML hygiene, and cross-repo maintainability.
