PROFILE
Dagan Mcgregor
Over three months, this developer enhanced the GeoNet/base-images repository by delivering five features focused on containerization, CI/CD, and security. They modernized RPM build images for Python packaging, standardized Docker images on AlmaLinux 8.10, and introduced a dedicated image for Dell EMC Unity storage management. Their work included removing legacy security scanning jobs to prepare for Tenable integration, reducing CI complexity and maintenance. Using Dockerfile, Shell, and YAML, they implemented automated setup pipelines, hardened environments with dedicated users, and aligned base images to eliminate drift. These efforts improved build reliability, security posture, and enabled more reproducible, maintainable deployment workflows.

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.
