January 2026 monthly summary for the bpg/terraform-provider-proxmox project. Focused on delivering container lifecycle flexibility and laying groundwork for more dynamic container management features.

Monthly summary for 2025-11 focusing on business value and technical achievements across two repositories: bpg/terraform-provider-proxmox and mautic/mautic. The work emphasizes reliable container deployment, improved mail delivery, expanded test coverage, and stable CI. Key features delivered: - bpg/terraform-provider-proxmox: Container Mount Options Configuration implemented, enabling users to specify mount options during container creation and update to improve flexibility and performance. Includes fixes to allow correct mountoptions, and wiring to use the current rootFS Volume during containerUpdate. Acceptance tests added. (Commit: c2dc3a75385d11eaf9740d4d871c4c6eabcaaab8) - mautic/mautic: Email Sending: Proper Sender Handling implemented in MailHelper to ensure correct SMTP authentication and reliable delivery. Tests updated to reflect the Sender header behavior. (Commits: 3769c03e4f421059d4521ce61f1a2dcd89111523; 103372629678426e8e9835e82a9afcbe60828985) Major bugs fixed: - bpg/terraform-provider-proxmox: Fixed container creation/update path to honor mountoptions and ensured correct mountoptions usage; updated to use the current rootFS Volume in containerUpdate. Acceptance tests added to prevent regressions. - mautic/mautic: Fixed incorrect email used for SMTP authentication and updated CI tests to explicitly set the Sender header for reliability. Overall impact and accomplishments: - Increased deployment reliability and performance for Proxmox containers through correct mount option handling and robust container updates, reducing support tickets related to misconfigurations. - Improved email deliverability and authentication reliability in Mautic, with broader test coverage and more stable CI. - Demonstrated end-to-end capabilities in container orchestration, mail workflow, testing strategies, and CI reliability. Technologies/skills demonstrated: - Terraform provider development, LXC/containerization, and acceptance testing for Proxmox - PHP-based email handling, SMTP authentication, test-driven development, and CI/test pipeline stabilization - Cross-repo collaboration and contribution traceability via commit history
