August 2025 monthly summary for bancolombia/devsecops-engine-tools: Delivered significant improvements to Prisma Cloud base image scanning and artifact management in release workflows. Base image handling now captures and stores the full list of base images, supports nested structures, and uses configurable label keys; added BASE_IMAGE_LABELS and LABEL_KEYS to ConfigTool.json; validation, retrieval, and tests were aligned across ImagesGateway and container_sca_scan.py; multiple fixes improved correctness (GET_IMAGE_BASE references BASE_IMAGE_LABELS, trailing commas removed, test_write_image_base_success updated). Release and CI/CD workflows were enhanced to package, upload, and manage artifacts more reliably, including artifact zipping, uploading, and workflow_dispatch-based manual uploads with tag input, and streamlined tag handling. These changes improve vulnerability analysis accuracy, build reproducibility, and release velocity. Technologies demonstrated include Python-based base image handling, JSON/config management, container scanning tooling, and GitHub Actions workflows.

June 2025 monthly summary for bancolombia/devsecops-engine-tools: Delivered two high-impact features to stabilize Linux release binaries and enable static builds, significantly improving release reliability and distribution readiness. Implemented a Docker-based Linux CI/CD pipeline, standardized Python 3.10 in the build image, targeted Ubuntu 20.04, corrected pip/pyinstaller usage, and ensured proper timezone setup and robust artifact uploads. Enabled static Linux release artifacts by integrating staticx, patchelf, and upx and packaging static binaries, with artifact uploading enabled for trunk releases. Addressed pipeline brittleness and environment mismatches by fixing Docker-in-Docker issues and multiple pip-related failures, validating the Ubuntu 20.04 test matrix, and improving release binaries versioning. Commits illustrating the work include fixes around Docker-in-Docker (fix: docker in docker in docker), pip fixes (fix: fix pip, fix: fix pip 2/3/4), tests for 20.04 (fix: test 20.04), version release binaries (fix: version relese binaries), and static build validation (fix: test staticx).
