July 2025 monthly summary focusing on key accomplishments, major fixes, and business value across two StackHPC repositories. Deliverables include: (1) Erlang packaging reliability on RHEL 9 arm64 by updating the repository URL to the RHEL base, resolving a CentOS Stream 9 divergence and missing libcrypto.so.3 dependency; (2) reintroduction and integration of the epoxy OpenStack repo for CentOS Stream 9 with updated build configuration and selective package exclusions to ensure clean integration; (3) multi-architecture container support for Rocky Linux 9, adding aarch64 builds, updating the GitHub Actions matrix, and introducing a manifest creation/push script to allow a single image tag across x86_64 and aarch64. These efforts broaden platform coverage, reduce deployment failures, and streamline CI/CD for multi-arch deployments.

December 2024 monthly summary for stackhpc/stackhpc-kayobe-config: Implemented Conditional IPA Collectors Activation to ensure IPA-related collectors (dmi-decode, extra-hardware, numa-topology) run only during IPA image builds. This optimization reduces needless execution during non-build phases, lowering runtime and resource usage while preserving build integrity. No major bugs fixed this month; existing CI guarantees stability with the new conditional path. Overall impact: faster, more predictable image builds and reduced CI load, enabling teams to iterate on IPA-related features more quickly. Technologies/skills demonstrated include Python-based build orchestration, feature flag/conditional execution, and CI/CD workflow integration.
