| Criterion | Native systemd service | Docker container |
|---|---|---|
| Process | Host executable and unit | Container entrypoint/runtime |
| Ports | Process bind address | Published host-to-container mapping |
| Data | Host paths owned by service user | Named volume or explicit bind mount |
| Logs | journald or app destination | Container logging driver/app destination |
| Updates | Package/artifact plus unit restart | New image plus container replacement |
| Dependencies | Unit ordering/readiness | Compose dependencies and health conditions |
Example choice
A single binary with one config file can be simplest as a native unit. A tested image with explicit volume and loopback-only port mapping can make a multi-dependency release repeatable.
Decision
Use the boundary you can inspect and recover. Publishing a Docker port can bypass assumptions about host firewall behavior.
