PROFILE
Glenn Morris
Greg Morris engineered and maintained the lsst-it/lsst-control repository, delivering robust configuration management and deployment automation for telescope control clusters. Over 14 months, he centralized and modernized infrastructure using Puppet, YAML, and Ruby, standardizing software versioning and streamlining upgrades across AuxTel, ComCam, and LSSTCam. His work included migrating data streaming from DDS to Kafka, enhancing network configuration reliability, and automating power and file transfer operations. By integrating DevOps practices and infrastructure as code, Greg reduced configuration drift, improved operational reliability, and enabled reproducible deployments. His technical depth ensured scalable, maintainable systems that supported evolving scientific and operational requirements.

Dec 1, 2025December 2025 — lsst-control: CCS Infrastructure Configuration and Reliability Enhancements across AuxTel, ComCam, and LSSTCam. Delivered standardized CCS software versions across all CCS nodes, implemented chrony-based time synchronization on LSSTCam shutter nodes, and added sudo permissions for observers to streamline CCS operations. The changes are reflected in commits that deploy CCS 42.0.4/42.0.3, configure timekeeping, and improve access control. These updates reduce configuration drift, improve operational reliability, and simplify nightly deployments, contributing to higher uptime and more repeatable runs.
