Production Solution & Architecture
Bind mount: docker run -v /host/path:/container/path. Volume: docker run -v myvolume:/container/path (Docker manages storage location). Use bind mounts for development (live code changes). Use named volumes for production data (better performance, portable). Avoid bind mounts in production — ties container to specific host path.

⚡ 60-Second Elevator Pitch Talking Points
- Immediate Triage: Bind mount: docker run -v /host/path:/container/path. Volume: docker run -v myvolume:/container
- Run targeted verification commands before modifying configuration.
- Automate permanent guardrails (CI check, alerts, IaC policy) to prevent recurrence.
