Manisha Arumugam developed and maintained network validation and deployment tooling across the Cray-HPE/csm-testing and docs-csm repositories, focusing on Kubernetes environments. She built automated test suites and troubleshooting runbooks for Cilium, leveraging Bash, YAML, and shell scripting to improve network reliability and accelerate incident resolution. Her work included refactoring test infrastructure to remove legacy dependencies, implementing dynamic version resolution for Alpine Linux in Nexus deployments, and enhancing documentation for CHN support and PXE boot diagnostics. Manisha’s contributions emphasized configuration management, DevOps, and technical writing, resulting in more maintainable systems, streamlined release processes, and improved operational clarity for users.

Month 2025-10 summary: Release readiness and documentation improvements across Cray-HPE/csm and docs-csm. Delivered CSM system release readiness including image and kernel bumps, Kubernetes/PIT/Storage Ceph/Compute image updates, and an index.yaml version bump, with cray-dns-powerdns upgraded to the latest stable across manifests to improve deployment stability and compatibility. Enhanced PXE boot troubleshooting documentation in docs-csm by adding a console command to aid diagnosing network interface settings. These efforts reduce deployment risk, accelerate releases, and improve triage efficiency through better cross-repo collaboration.
