Monthly summary for 2025-09 (tiiuae/ghaf-infra): Delivered focused cleanup and automation to reduce maintenance burden and optimize resource usage. Key changes include removing non-builder Ficolo components, automating old system profile pruning, and cleaning up obsolete monitoring documentation. These efforts improve deployment stability, free up disk space, and clarify operational docs, with full traceability to commits.

Month 2025-08 recap focusing on business value and technical achievements across two repos (tiiuae/ghaf-infra and tiiuae/ghaf-jenkins-pipeline). Key features delivered: - Proactive Garbage Collection threshold adjustment for hetzci-prod and hetzci-dev to trigger GC earlier (min-free/max-free ~70GB), improving reliability under growing image caches and disk pressure. - Stabilized Jenkins artifact purge by removing explicit deletion of empty directories, allowing Rclone to manage empties and reducing failures when target dirs do not exist. Major bugs fixed: - Azure VM Disk Image Name Correction in Terraform: ensured the correct, updated disk image is used after a nixpkgs update, preserving VM deployment integrity. - Artifact Purging Directory Handling Stabilization: fixed purge script failure caused by explicit removal of empty dirs. Overall impact and accomplishments: - Enhanced deployment reliability and disk space management for cloud infra and CI pipelines; reduced risk of failed VM provisioning and artifact purges; streamlined scripts for maintainability. - Improved operational resilience with fewer edge-case failures in automated workflows, supporting faster release cycles. Technologies/skills demonstrated: - Terraform and Azure VM image handling, nixpkgs-aware deployments - Garbage collection tuning and capacity planning for Hetzner-based environments - Jenkins CI/CD scripting and Rclone-based artifact management

July 2025 monthly summary for tiiuae/ghaf-infra: Infrastructure cleanup focused on decommissioning the Himalia host, with comprehensive removal of host-specific configurations and related deployment definitions, accompanied by documentation updates. The change reduces operational risk and maintenance overhead while improving security posture by eliminating unused infrastructure.

June 2025 monthly summary for tiiuae/ghaf-infra focusing on CI infrastructure modernization, performance improvements, and platform compatibility. Delivered upgrades to the production Jenkins VM, updated NixOS/Nix tooling, and improved Azure agent compatibility to reduce environment drift and accelerate CI pipelines.

May 2025 monthly summary focusing on key accomplishments and business impact. Delivered reliability improvements in the Jenkins pipeline and refreshed dependencies to align with upstream tools. Key changes include wiring WebDAV parameters for rclone artifact handling, cleanup of stale directories to prevent conflicts, and modernization of the rclone dependency across the infra stack.

February 2025 — Delivered automated performance testing pipelines across Ghaf repositories, enabling faster feedback on performance regressions and more reliable CI/CD. Implemented a Jenkins-based Ghaf performance testing pipeline in the ghaf-jenkins-pipeline repo, including repository checkout, cross-target builds, hardware tests, and post-build artifact cleanup, with optimized scheduling for nightly and performance testing pipelines. Extended the infra with a dedicated perf-test pipeline configuration that maps Ghaf performance tests to ghaf-perftest-pipeline, enabling seamless CI/CD integration. Fixed a DNS configuration issue by removing an obsolete entry (172.18.20.100) in ficolo to simplify network settings and reduce deployment friction. These changes improve test coverage, accelerate delivery cycles, and reduce manual maintenance across repos.

Monthly work summary for 2025-01 focused on ghaf-infra Harmonia configuration compatibility. Delivered a targeted config migration to align with newer Harmonia service versions, ensuring smoother upgrades and reduced risk of runtime failures.

December 2024 accomplishments for tiiuae/ghaf-infra focused on delivering secure, scalable web serving and strengthening access governance for ghaf-webserver. Delivered two major features with clear business value: (1) secure Nginx web server deployment with SSL for vednenemo.dev and restoration of binary cache functionality (harmonia signing, SSL/reverse proxy), and (2) structured user access management for Gala uploaders and release-team test agents. No explicit bug fixes of note; a rollback was performed to restore the binary cache configuration where a prior cleanup had been applied.

Month: 2024-11. Focused on delivering automated deployment capabilities for Ghaf webserver within the ghaf-infra repository, with emphasis on infrastructure, secrets management, system settings, and disk configurations, integrated into deployment and task management workflows. Added access for a new operator to operate/manage the webserver as part of the deployment workflow. No major bug fixes recorded this month; work centered on delivering a reproducible, secure, and operable webserver deployment baseline to enable rapid rollouts and controlled access.
