Persist binary data to a Docker volume
N8N_DEFAULT_BINARY_DATA_MODE=filesystem saves uploads to the container’s local disk.
Unless that directory is persisted via a named volume, all files will vanish on every redeploy.
Recommended follow-up:
- N8N_DEFAULT_BINARY_DATA_MODE=filesystem
+ # Explicitly set the path and document it
+ - N8N_BINARY_DATA_STORAGE_PATH=/data/n8n…and ensure the n8n service includes
volumes:
- n8n_data:/data/n8nThis aligns with the team rule that all service data must be persisted in ./volumes/-mapped Docker volumes.
🏁 Script executed:
#!/bin/bash
# Check for existing n8n data volume mappings in docker-compose.prod.yml

Persist n8n binary data via Docker volume
The n8n service currently writes uploads to the container’s filesystem (N8N_DEFAULT_BINARY_DATA_MODE=filesystem) but doesn’t mount any volume at /data/n8n, so all files will be lost on each redeploy.
Apply these changes in docker-compose.prod.yml:
services:
n8n:
environment:
- N8N_DEFAULT_BINARY_DATA_MODE=filesystem
+ - N8N_BINARY_DATA_STORAGE_PATH=/data/n8n
volumes:
+ - n8n_data:/data/n8nEnsure your root-level volume definition binds into ./volumes/n8n_data per project conventions:
volumes:
n8n_data:
driver: local
driver_opts:
type: none
o: bind
- device: /data/n8n
+ device: ./volumes/n8n_dataThis guarantees that all binary uploads persist across deployments under volumes/n8n_data.
🤖 Prompt for AI Agents
In docker-compose.prod.yml around lines 21 to 22, the n8n service is set to
store binary data on the container filesystem without mounting a volume, causing
data loss on redeploy. Fix this by adding a volume mount for the n8n service
that binds the container path /data/n8n to a host directory like
./volumes/n8n_data. Also, define this volume at the root level of the
docker-compose file to ensure persistent storage of binary uploads across
deployments.
