If the Job Cannot Show What It Did, Somebody Will Do It Again

Описание и применение

Автоматизированный процесс развертывания подтверждал успех без проверки фактических изменений, что приводило к ошибкам и ручной проверке. Внедрение чтения состояния и журналирования устранило необходимость ручного контроля и выявило скрытые сбои.

Задача

Automated provisioning jobs reported success without confirming actual changes, leading to undetected failures and manual rework.

Результат

Implemented state verification and logging reduced manual review time, surfaced hidden failures, and enabled automated drift detection.

Рабочий процесс

• Run provisioning job
• Script performs API calls
• Script checks API acceptance, writes green tick
• Engineer manually reviews console to confirm settings

Доказательства

Our automation told us that it had run. It did not tell us what it had changed, and an exit code of zero is a statement about a script, not about a system.

Источник

A daily reconciliation compares intent against reality for the whole estate, so drift is reported rather than discovered.
