Quick Answer
Self-hosted n8n can be configured with environment variables, a configuration file, or the database, and environment variables are usually the clearest option for container deployments.
Key Facts
- Main methods
- Environment variables, configuration file, and database settings.
- Container fit
- Environment variables are usually the easiest method for Docker and Compose deployments.
- Restart requirement
- Runtime configuration changes commonly require restarting n8n.
- Secrets
- Use environment files or secret management instead of committing secrets.
Recommended Steps
- Decide whether the setting belongs in deployment config, a file, or the database.
- Prefer environment variables for Docker, Compose, and most server deployments.
- Group variables by concern, such as endpoints, database, queue, nodes, or security.
- Keep credentials and encryption keys outside public repositories.
- Restart n8n and check logs after changing configuration.
Verification
- n8n starts without configuration warnings.
- The intended behavior changes after restart.
- The active configuration is documented for future upgrades.
Warnings
- Mixing multiple configuration methods can make later debugging harder.
- Configuration drift between staging and production can break workflows after deployment.
