Use when

Self-hosted tools store configuration, workflows or application state locally.

services:
  n8n:
    image: n8nio/n8n:latest
    volumes:
      - n8n_data:/home/node/.n8n

volumes:
  n8n_data:

Why it works

Named volumes have a lifecycle independent from an individual container instance.

Operational notes

A persistent volume is not a backup. Export or snapshot important state separately.
