Manual secret rotation scripts require operator intervention, lack health checks, and cause downtime during failures.
Manual secret rotation scripts require operator intervention, lack health checks, and cause downtime during failures.
| Category | Docker Secret Operator | Manual Shell Scripts + Cron |
|---|---|---|
| Rotation Method | Automatic detection of secret changes → new container spawned → health checks → atomic swap | Cron job → shell script → manual validation → container restart (or custom logic) |
| Downtime on Rotation | 0 seconds (blue-green swap, atomic) | 5-10 minutes (rolling restart, potential connection drops) |
| Health Validation | Mandatory health checks before traffic switch. Failed rotation triggers automatic rollback. | Optional (depends on script implementation, usually absent) |
| Failure Recovery | Automatic: Agent detects in-flight rotation state on restart, auto-rollback older than 5 minutes, orphaned containers cleaned up | Manual: Operator must SSH, inspect state, manually restart or rollback |
| Compliance & Audit | Structured JSON audit logs (SOC 2, ISO 27001, PCI-DSS ready), immutable logging required | Custom log parsing, no standardization, compliance gaps common |
| Operational Complexity | Setup: 3 commands. Rotation: automatic. Failure response: automatic. | Setup: custom script development. Rotation: monitor cron. Failure response: manual debug |
0 seconds (atomic blue-green swap)
5-10 minutes per rotation (rolling restarts, request drains)
Automatic: checkpoint saved, agent detects incomplete rotation on restart, auto-rollback if > 5 minutes old
Manual: on-call engineer wakes up, SSHes in, diagnoses, restarts manually
Mandatory before swap. New container must pass health checks or entire rotation aborts.
Usually none. Script just restarts container and hopes it comes up.
Native: works directly with Docker Engine. No integration needed.
Possible but requires custom script logic for docker inspect, restart, wait loops
Low: install DSO, write dso.yaml, done. Rotations happen automatically.
High: write scripts, debug cron, monitor for failures, respond to alerts, manual rollbacks
Production workloads, compliance requirements, zero-downtime needs, or teams avoiding on-call escalations
Rare. Manual scripts should not be used for production secrets.
