PROFILE
Glenn Morris
Worked on the lsst-it/lsst-control repository to deliver infrastructure, deployment, and monitoring enhancements across multiple camera clusters. Focused on configuration management and automation using Puppet, Bash, and Ruby, this developer upgraded CCS software versions, streamlined database migrations, and introduced webhook-based alerting to improve operational reliability. They enabled image processing workflows with Cantaloupe, enhanced log management, and automated database backups, reducing maintenance overhead and configuration drift. Their approach emphasized release engineering discipline, traceable commits, and proactive system monitoring. The work improved deployment consistency, observability, and incident response, supporting science operations with robust infrastructure and maintainable, test-driven configuration management practices.

Jul 1, 2026July 2026 monthly summary for lsst-control (lsst-it/lsst-control). Key features delivered: - Cluster CCS software version updates across AuxTel, ComCam, and LSTCam to 44.0.3/44.0.4, enabling compatibility and access to latest features and fixes. - Enhanced webhook alert formatting in ccs_monit by upgrading to 3.3.0 for clearer, more actionable alerts. Major bugs fixed: - No major bugs fixed this month (focus was on software upgrades and monitoring enhancements). Overall impact and accomplishments: - Improved system compatibility and reliability across multiple clusters, reducing risk of outages due to version drift. - Faster, clearer incident response from improved webhook alerts, strengthening night operations and support for science teams. - Maintained and improved deployment consistency via Puppetfile-driven updates, enabling repeatable releases. Technologies/skills demonstrated: - CCS version management and multi-cluster coordination (AuxTel, ComCam, LSTCam). - Release engineering through Puppetfile and commit hygiene (traceability via commits 602358f8..., 05b914fa..., fa933694...). - Monitoring and alerting improvements with ccs_monit."
