PROFILE
Dagan Mcgregor
Worked extensively on the GeoNet/base-images repository, delivering a series of containerized solutions to standardize and modernize build environments for RPM packaging and storage management. Leveraged Docker, Python scripting, and YAML to create and maintain AlmaLinux-based images supporting multiple OS versions, enabling reproducible builds and streamlined CI/CD workflows. Enhanced security by migrating vulnerability scanning workflows and introducing environment secret handling, while removing brittle scripting in favor of configuration-driven approaches. Focused on maintainability and compatibility, the work included automated setup pipelines, dedicated user environments, and integration with GitHub Actions, resulting in reduced manual toil and improved reliability for package inspection and deployment.

Apr 1, 2025April 2025 monthly summary for GeoNet/base-images focusing on container image standards, security, and reproducibility. Key features delivered include a new AlmaLinux 8.10-based Docker image for gempa package inspection, pre-configured with Python 3.11, supported by an automated setup/update process and a dedicated user environment to improve security and consistency. In addition, base-image alignment removed AlmaLinux 8.9 and migrated to AlmaLinux 8.10 across the repository to eliminate drift and ensure reproducible builds. Major bugs fixed include correcting base-image references to AlmaLinux 8.10 to resolve drift between the repository and downstream environments and to enable consistent, repeatable deployments. Overall impact and accomplishments: Standardized container environments across the base-images repo, reduced build and deployment toil, and improved security posture through dedicated user setups. These changes enable faster onboarding, more reliable testing, and smoother downstream integration for gempa package workflows. Technologies/skills demonstrated: Docker image design and maintenance, AlmaLinux-based images, Python 3.11, automated setup/update pipelines, environment hardening with dedicated user, release engineering and commit-driven traceability.

Mar 1, 2025March 2025 monthly summary for GeoNet/base-images. Delivered two major features: 1) RPM Build Image Modernization for Python Packaging to improve build reliability and CI efficiency by pre-installing Python 3.11 RPM macros and upgrading the rpmbuild base OS to AlmaLinux 8.10; 2) Dell EMC Unity Storage Management Docker Image that adds a dedicated image to manage Unity storage via the Unity CLI, standardized on AlmaLinux 8.9 with the Unity CLI RPM and an entrypoint to uemcli.sh. These changes standardize tooling, reduce CI runtimes, and enable easier storage automation. Key outcomes include more reliable builds, faster feedback loops, and ready-to-use images for storage management.

Dec 1, 2024December 2024 monthly summary for GeoNet/base-images. Focused on CI security scanning migration prep by removing the Trivy scanner job from the CI workflow and deleting scan.yml to enable Tenable integration. This reduces CI noise, lowers maintenance, and establishes groundwork for a more scalable vulnerability management pipeline. Commit reference: e5a88ab5d7b1f0d73f91d9e5b7dc1df5639c49b2.
