Runbook Automation (Python, Ansible, PostgreSQL, Redis, FastAPI, Docker) overview

A self-service runbook automation platform that codifies operational procedures into executable workflows accessible through a web interface. FastAPI serves the runbook catalog and execution API with role-based access control and approval gates for sensitive operations. Ansible playbooks encode the actual infrastructure actions — server restarts, certificate rotations, database failovers — with idempotent execution guarantees. PostgreSQL stores runbook definitions, execution history, and approval audit trails. Redis manages job queues, execution locks to prevent concurrent conflicting operations, and real-time status streaming. Docker containers isolate Ansible execution environments with pinned dependency versions. The tradeoff is maintaining runbook accuracy as infrastructure evolves and the risk of automated actions in degraded system states.
