Deploy and Host n8n with Postgres on Railway

n8n with Postgres is a simple Railway template for running n8n with a reliable PostgreSQL database and persistent storage. n8n is an open-source workflow automation tool that helps you connect apps, APIs, and services to automate repetitive tasks, build integrations, and run scheduled workflows.

About Hosting n8n with Postgres

Hosting n8n with Postgres on Railway gives you a straightforward automation setup that just works. The template deploys n8n together with a Postgres database for storing workflows, credentials metadata, executions, settings, and other application data.

This template also includes persistent storage through a mounted volume at /data, so local n8n files can remain available across deployments and restarts. Railway handles deployment, networking, database provisioning, and service management, so you can focus on building workflows instead of managing infrastructure.

Common Use Cases

Automating repetitive business tasks
Connecting APIs, apps, and databases
Running scheduled workflows and background jobs
Building internal automation tools
Creating lightweight data sync and integration workflows

Deployment Dependencies

Architecture

This template uses a simple n8n + Postgres architecture:

Browser / Webhooks

Postgres Database

Persistent Storage: Railway Volume mounted at /data

The n8n application provides the web UI, receives webhook traffic, runs workflows, and connects to Postgres for persistent application data. The mounted Railway Volume provides persistent file storage for data that needs to survive restarts and redeployments.

Services

This template includes the following Railway services:

n8n Application

The n8n service runs the web UI, API, webhook receiver, and workflow execution runtime.

Image: n8nio/n8n:latest
Role: Web UI, API, webhook receiver, workflow runner
Public: Yes
Volume: /data

PostgreSQL

PostgreSQL stores n8n workflows, credentials metadata, executions, settings, and other application data.

Role: Primary database
Public: No

Public Web Access

Expose the n8n application service publicly so users can access the n8n web UI through the generated Railway domain or a custom domain.

Recommended public port:

After deployment, open the Railway-provided domain in your browser and complete the initial n8n owner account setup.

Persistent Storage

This template includes a Railway Volume mounted at /data for persistent storage. This helps keep local files available across restarts and redeployments.

PostgreSQL stores the main n8n application data, including workflows, credentials metadata, executions, settings, and other database-backed records. The mounted volume is useful for local file persistence when workflows need to read or write files on disk.

Authentication and Security

n8n creates the owner account during the first setup in the web UI. After opening the public Railway URL, complete the setup screen and save your login credentials securely.

Recommended security practices:

Use a strong owner account password during first setup.
Keep PostgreSQL private inside the Railway project.
Expose only the n8n application service publicly.
Use a stable encryption key so credentials and encrypted workflow data remain readable across deployments.
Avoid changing the encryption key after credentials have been created.

Implementation Details

This template deploys n8n as a simple Railway stack:

n8n Application + PostgreSQL + Persistent Storage

The n8n service uses the official n8n Docker image and connects to the Railway Postgres database. The service exposes the n8n web UI on port 5678 and uses a Railway Volume mounted at /data for persistent local file storage.

This setup is ideal for users who want a clean n8n deployment with Postgres-backed persistence and a mounted volume for local file storage.

Why Deploy n8n with Postgres on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway hosts your infrastructure so you do not have to deal with manual server configuration, while still allowing you to scale your services as needed.

By deploying n8n with Postgres on Railway, you get a practical automation setup with minimal burden. Host your workflows, database, APIs, AI agents, and supporting services in one place.
