February 2026 focused on increasing container provisioning flexibility and stabilizing CI for Fedora 44, delivering features that improve startup behavior of container images and support for image-mode provisioning, while cleaning up CI reliability. Key achievements: - Pass plan environment variables to containers via an env-file during initialization, enabling initialization-time config for container images (ENV-file approach; supports --env-file usage). - Add image-mode support for prepare/shell scripts with a CommandCollector and deferred execution, including is_image_mode detection, immediate vs deferred commands, and on_step_complete hooks, plus workdir bind mounting for access to plan data during image builds. - Fix local RPM installation in Image Mode by removing unnecessary file copying due to volume mounting, preserving RPMs from the mounted workdir and adding tests for the scenario. - Stabilize CI for Fedora 44 by marking known issues as expected failures (xfail) to prevent CI noise and focus on regressions. Overall impact and accomplishments: - Improved provisioning flexibility and reliability in image-based deployments, enabling complex init workflows and script execution during image rebuilds. - Reduced build-time frictions and potential runtime failures in image-mode provisioning, with clearer separation between immediate and deferred commands. - More stable CI, faster feedback loops, and clearer signal on real regressions, accelerating development velocity. Technologies/skills demonstrated: - Podman-based container orchestration, env-file handling, and image rebuild workflows. - Image-mode provisioning concepts, CommandCollector pattern, and deferred command execution. - Bind mounts with proper SELinux-aware mounting for build-time access to plan data. - CI/test configuration management for Fedora distributions.
