PROFILE
Callum Morris
Over eight months, Chris Morris engineered and maintained containerized build environments in the GeoNet/base-images repository, focusing on reproducibility, security, and compatibility. He upgraded Docker images to support evolving Python and Node.js versions, integrated dependency management with Poetry and poetry.lock, and ensured deterministic builds for ArcGIS and data tooling. Using Dockerfile, YAML, and Shell, Chris addressed CI/CD configuration, containerization, and dependency upgrades, including security patching for Go and Node.js runtimes. His work stabilized build pipelines, improved environment parity across development and production, and reduced manual maintenance, demonstrating depth in DevOps, reproducible builds, and Python packaging within a modern CI/CD workflow.

Oct 1, 2025Monthly summary for 2025-10: GeoNet/base-images delivered a major environment upgrade to prepare for production deployments and future feature work. Key features delivered: Upgraded Python to 3.12 across the base image, refreshed core dependencies (arcgis, azure-core, boto3, etc.), updated Dockerfile and poetry.lock to reflect dependency changes, and extended the Docker image build matrix to include a 3.12.9-bookworm tag for distribution. Major bugs fixed: none identified this month. Overall impact and accomplishments: This upgrade improves compatibility with modern Python ecosystems, reduces risk in downstream deployments, and broadens supported runtime environments for GeoNet services. It also positions the team for easier maintenance and future upgrades. Technologies/skills demonstrated: Python packaging and dependency management (Poetry), Docker image construction and tagging, dependency updates, and build matrix expansion for multi-version support.

May 1, 2025May 2025 Monthly Summary for GeoNet/base-images. Focused on stabilizing and modernizing the Docker image build lifecycle and refreshing dependencies to support broader Python version coverage and data tooling compatibility. Delivered three key improvements that enhance reliability, performance, and maintainability across environments. Key achievements: - Docker image stability and build environment improvements: Upgraded Poetry to 2.1.3 and added a Python 3.11.9-bullseye image to improve build reliability and cross-version parity across environments. - PyArrow build compatibility fix: Switched base image from Alpine to Debian to resolve pyarrow wheel compatibility issues, restoring successful builds. - Dependency upgrades for core libraries: Bumped ArcGIS and Pandas to latest stable releases to improve stability, performance, and compatibility with data tooling. Impact and accomplishments: - More reliable image builds with consistent Python version support, reducing CI failures and manual debugging. - Enhanced compatibility with data-processing tools (pyarrow) and downstream consumers relying on stable wheels. - Reduced maintenance overhead through up-to-date core libraries and streamlined image creation. Technologies and skills demonstrated: - Docker image design and optimization, Poetry-based Python packaging, Debian-based image strategy, Python version management, and dependency maintenance (ArcGIS, Pandas).
