Devops notes from the field
summary
"Devops notes from the field" describes building repeatable environments for a manufacturing execution system at Jaguar Land Rover: bootstrapping machines, upgrading to PowerShell 5, compiling ~2,000‑line MOF configurations with ~100 items, splitting parameters from logic, and producing Pester tests plus Excel audit workbooks via ImportExcel. The work requires 12 modules (6 gallery, 6 custom), ~45 resource classes, lots of cluster and disk edge cases, and ultimately delivers automated builds and readable proof that mostly work in practice.
